Here is a patch to allow users to apt-cyg search <packagename>, (in addition to 
apt-cyg find <packagename>). This more closely mirrors apt-cache search 
<packagename>.

What steps will reproduce the problem?
1. apt-cyg install (anything)

What is the expected output? What do you see instead?
When apt-cyg worked, I would show the requirement install tree like this:
* package
** cygwin
*** base-cygwin
** requirement
*** cygwin
**** base-cygwin
** ...

Recently, the servers have been updated so the package "cygwin", which apt-cyg 
thinks every package requires, requires _autorebase, and that made apt-cyg 
infinitely recurse. I would show the new requirement install tree like this:
* package
** cygwin
*** base-cygwin
*** _autorebase

Error updating setup.ini, reverting

What version of the product are you using? On what operating system?

Latest apt-cyg code from trunk, Windows 7, Cygwin 1.7.23.

Please provide any additional information below.

The mirrors now contain a folder representing the architecture, either x86 or 
x86_64, example: http://cygwin.mirror.uk.sargasso.net/

Cygwin recently changed the layout of the mirror directories to look for an 
arch type (x86 or x86_64)

When running apt-cyg find <foo>, the output currently only lists the
package names.  Having 2 more columns to indicate 1) the currently
installed version and 2) the version available according to setup.bz would
make it easy to know what's up to date, etc.

Hi
 I add an option "src" to get the source code of packages. For example: 
apt-cyg src wget
will fetch the source code of wget and save it wo /usr/src
wish it's helpful

I'd like if there was an "apt-cyg upgrade" feature, like the "apt-get 
upgrade" feature on Debian-based systems. This would mean you could do an 
"apt-get update && apt-get upgrade" to upgrade everything in cygwin.

The instructions for this should probably clearly state that it doesn't 
upgrade apt-cyg or cygwin itself if it doesn't. Then again, the instructions 
could easily have upgrade instructions for them too. 

Hi had a quick look at apt-cyg and basically I like it, but it lacks the 
possibility to handle multiple mirrors at once like setup.exe does.

I usually start setup.exe like "setup.exe -K http://cygwinports.org/ports.gpg" 
and then select a normal mirror AND the cygwinports mirror. This way I get the 
packets of both mirrors in one list and can install and update them together.

I'd really like apt-cyg to be able of this too.

One note, setup.exe has a bug with this currently, as e. g. git is in both 
mirrors, but with different versions (normal mirror now newer than 
cygwinports), but only the versions from cygwinports are shown, not the ones 
from the normal mirror. This use-case should be handled properly in apt-cyg if 
the feature gets implemented.

Previously apt-cyg worked without problems, today I get this error:

$ LANG=C apt-cyg update
Working directory is /setup
Mirror is
/setup.bz2: Scheme missing.
/setup.ini: Scheme missing.
Error updating setup.ini, reverting
$

Here some informations:

$ apt-cyg --version
apt-cyg version 0.57

apt-cyg find is a bit odd... apt-cyg search is more natural if you are making 
it as useful as apt-get is.

That said, here is a patch that allows this.

Now you can do:

  alias apt-get='apt-cyg'
  alias apt-cache='apt-cyg'

and you don't need to rewire your brain ;-)

in function 

function getsetup()
{
  if test "$noscripts" == "0" -a "$noupdate" == "0"
  then
    touch setup.ini
    mv setup.ini setup.ini-save
//    wget -N $mirror/setup.bz2
    wget -N $mirror/x86/setup.bz2
    if test -e setup.bz2 && test $? -eq 0


THEN

in function 

  install)

    ..........
    ..........

    echo "Unpacking..."
//  cat $file | bunzip2 | tar > "/etc/setup/$pkg.lst" xvf - -C /
    cat $file  | xz -d | tar > "/etc/setup/$pkg.lst" xvf - -C /
    gzip -f "/etc/setup/$pkg.lst"
    cd ../..




THE
the attached file is a sample file of architure x86 using mirrors.ustc.edu.cn

First it would be nice to either have the instructions on the "project 
home" page or at least a featured link to the wiki GettingStarted page.

Next i think the instructions for the installation could be simplified. How 
about something like this:

First install subversion and wget through the standard cygwin setup 
program. Then run the following commands:
{{{
svn export http://apt-cyg.googlecode.com/svn/trunk/apt-cyg /bin/apt-cyg
chmod +x /bin/apt-cyg
}}}

I've found this error several times, but I'm going to give you an example
of just one package this is occurring with:

The example I am giving is attempting to install the kdelibs package Please
note that apt-cygports is an alias for the following 
alias apt-cygports='apt-cyg -m ftp://sourceware.org/pub/cygwinports/'

When I search for the kdelibs I get this:

$ apt-cygports -u find kdelibs
Working directory is /cygdrive/c/temp/cygwin
Mirror is ftp://sourceware.org/pub/cygwinports/

Searching for installed packages matching kdelibs:
kdelibs-data
kdelibs-devel
kdelibs4

Searching for installable packages matching kdelibs:
kdelibs
kdelibs-bin
kdelibs-data
kdelibs-devel
kdelibs4

However when I go to install kdelibs it always fails:

$ apt-cygports -u install kdelibs
Working directory is /cygdrive/c/temp/cygwin
Mirror is ftp://sourceware.org/pub/cygwinports/

Installing kdelibs

Why does it come back as a HTML listing rather than just install the package??


Using apt-cyg version 0.57 on windows xp sp3 with cygwin

Now only the latest version of a package can be installed. It would be nice to 
be able to specify this.

As far as I understand Cygwin only has the latest and previous versions 
available, but this is at least a little better than just the latest :-)

What steps will reproduce the problem?
1. launch every commands thats require remote setup.ini
ex:
   apt-cyg install nano

What is the expected output? What do you see instead?
I expeted the installation process but i found:

What version of the product are you using? On what operating system?
r18 on Windows

Please provide any additional information below.


I found a solution: with new upgrade of cygwin the repos location change so i 
put in /etc/setup/last-mirrors this:

   http://mirrors.kernel.org/sourceware/cygwin/x86/

*Updated mirror changes but only include x86 packages.
*Support for xz packages.

Files with "xz" extensions seem not to be installed with apt-cyg

What steps will reproduce the problem?
1. fresh install cygwin with default plus wget
2. try installing LibXpm4
3. get error "bunzip2: (stdin) is not a bzip2 file."

What is the expected output? What do you see instead?
packages should be installed without this error

What version of the product are you using? On what operating system?
v0.58

Please provide any additional information below.

After renaming 'apt-cyg' to 'apt', I got the following error during install
of a package:

/usr/bin/apt: line 378: apt-cyg: command not found

Guess it should invoke $0 instead?

(Works very well otherwise. Much more convenient than setup. Thanks!)

It would be very useful to make apt-cyg part of cygwin so we could install it 
without extra steps.

I attached a patch that resolves the problem (useful when you're doing
several "apt-cyg find" in a row)

Thanks for this nifty script, I've always found the Cygwin graphical
installer to be very annoying!

apt-cyg install any_package

will redownload  setup.bz2 for every package in dependences,
apparently it does not care about --noscripts switch

please see suggested patch in attachment 

IMHO it will be more convenient if apt-cyg does case-insensitive search just 
like aptitude and apt-cache does.
With a search word more than 2..3 letters long, there won't be too many hits 
among ~2000 packages in Cygwin.

Assuming GAawk, ``BEGIN { IGNORECASE=1; }'' will suffice.

Some packages (such as subversion and mc) don't "actually" get installed. 
apt-cyg says the install completed successfully, but I still can't use the 
command.

What steps will reproduce the problem?
1. $ apt-cyg install mc #or some other package
2. $ mc #command installed in package

What is the expected output? What do you see instead?
Instead of running mc (which should have been installed), there is an error 
saying the command is not found

What version of the product are you using? On what operating system?
apt-cyg version 0.58
mintty 1.2-beta1 on x64 system

The new fork is https://github.com/wuyangnju/apt-cyg. It has solved below 
problems:

Cygwin has distinguished 64bit version from 32bit version, and so does the 
repositories.

Some packages(like python) have started using xz as its compressor rather than 
bzip2.

What steps will reproduce the problem?
1. apt-cyg install gs
2. apt-cyg find gs
3. apt-cyg find ghostscript

What is the expected output? What do you see instead?
It should download setup.bz2 once not three times.  Use wget's -m or like 
gentoo not redownload files but once a day.

What version of the product are you using? On what operating system?
most recent trunk version.

Please provide any additional information below.

What steps will reproduce the problem?
1. apt-cyg install unzip

What is the expected output? What do you see instead?

Expect to find unzip installed afterwards.  Instead, I see output

Installing unzip
Package unzip not found or ambiguous name, exiting

What version of the product are you using? On what operating system?

--version says "apt-cyg version 0.57" 

Please provide any additional information below.

Workaround is to use setup.exe's gui to install unzip.

What steps will reproduce the problem?
1. apt-cyg update
2. apt-cyg install openssh
3.

What is the expected output? What do you see instead?
Installing openssh; at least downloading the package

What version of the product are you using? On what operating system?
apt-cyg version 0.57

Please provide any additional information below.

I believe the expected output would have been something other than "Error

----
What version of the product are you using? On what operating system?
----
I downloaded the latest version and installed it with the following commands:

  10  wget http://apt-cyg.googlecode.com/svn/trunk/apt-cyg
  11  chmod +x apt-cyg
  14  mv apt-cyg /usr/local/bin/

----
Please provide any additional information below.
----
This reminds me of an issue which I encountered when running the old CYGWIN 
setup.exe installer and was only resolved by downloading the latest 
setup-x86.exe.  I know the difference is a new url or location of some mirror 
index file.  I will take a look at the source code and see if I can figure this 
out.

(Just took a look at a mirror, and I think it is as simple as adding "/x86/ or 
"/x86_64" to the mirror url.... 

What steps will reproduce the problem?
1. Follow Quick start instructions on home page (svn step then chmod step)
2. Try to use apt-cyg as in the example: # apt-cyg install nano

What is the expected output? What do you see instead?

Result should be:
apt-cyg should run and try to install nano.  

Instead it is:
bash: apt-cyg: command not found

What version of the product are you using? On what operating system?
apt-cyg 0.57
OS: CYGWIN_NT-5.1 1.7.1(0.218/5/3) 2009-12-07 11:48 i686 Cygwin

Please provide any additional information below.
Running using the explicit path /bin/apt-cyg/apt-cyg works as expected and
nano is installed.

What use apt-cyg 64 bit ?

apt-cyg dot no rumming for cingwin64

please help

On fresh install, apt-cyg will try to dl setup.bz2 from 
//mirror.mcs.anl.gov/pub/cygwin/setup.bz2 instead of 
//mirror.mcs.anl.gov/pub/cygwin/x86/setup.bz2

easy fix: on line 98, replace
CODE wget -N $mirror/setup.bz2
by
CODE wget -N $mirror/x86/setup.bz2


What version of the product are you using? On what operating system?
Win 7 x86

I would like to augment apt-cyg such that cygwin and cygwinports could be 
supported simultaneously.

mirror="`head -1 /etc/setup/last-mirror`"
to
declare -a mirrors=$(cat /etc/setup/last-mirrors)


Then proceed with wrapping the following functions in the appropriate for-loops:

findworkspace()
getsetup()
install()

Have you any objection, or might this already be underway?

What steps will reproduce the problem?
1. apt-cyg install fdupes
2.
3.

What is the expected output? What do you see instead?
Expected to successfully install the package fdupes.
Instead failed to download the package

What version of the product are you using? On what operating system?
0.57, windows 7 x64

Please provide any additional information below.
since now Cygwin supports both x86_64 and x86, package description is now 
prefixed with either x86_64 or x86, for example "install: 
x86_64/release/fdupes/fdupes-1.50-PR2-2.tar.bz2 49285 
af716582bdb43075a226c0dbd081f810". Because the mirror url also gets either 
x86_64 or x86 as the last part, a composed full package url would be like 
"http://mirrors.neusoft.edu.cn/cygwin/x86_64/x86_64/release/fdupes/fdupes-1.50-P
R2-3.tar.bz2", which is not correct.

What steps will reproduce the problem?
- when try to running the binary from /bin/apt-cyg

What is the expected output? What do you see instead?

1. Cygwin package path has been altered to differenciate 32bit (x86) and 64-bit 
(x86_64) and installation fails

2. Some of the packages (like vim) are packed with lzlm compression with 
extension .xz and hence bzip2 doesn't handle this

Please provide any additional information below.

apt-cyg for 64-bit cygwin did not find the correct path for the setup.bz2 and 
setup.ini.

Find the attached patch to fix the issue

What steps will reproduce the problem?
1. On a Cycgwin install without gcc. Install gcc.  

What is the expected output? What do you see instead?
The postinstall script should run. However, you will get access denied error 
when apt-cyg attempts to run the postinstall script.

What version of the product are you using? On what operating system?
Most recent SVN.
Cygwin on Windows 7.

Please provide any additional information below.
This is a simple problem. Execute privileges are not set for the gcc 
postinstall script. I added a chmod line to set them for each post install 
before running it. I assumed the same problem could occur for remove scripts so 
I did it there as well. All works great now. I've attached a simple patch to 
implement this fix.

i fork this project on 'https://github.com/Simuc/apt-cyg'

add option '--x64' for release 'x86' and 'x86_64'
support '*.xz' package
add command 'reinstall' when previous installation has failed

I don't know what the possible values for last-cache are in setup.rc, but since 
my account name has a <SPACE> in it, the following works.

Also, you did quote the mkdir and cd in ONE place, but another one was left 
unquoted.

$ apt-cyg --version
apt-cyg version 0.59

$ diff /usr/bin/apt-cyg /usr/bin/apt-cyg.DIST

<     print $0

What steps will reproduce the problem?
1. Install cygwin x86_64
2. Install apt-cyg
3. Run 'apt-cyg install git'

What is the expected output? What do you see instead?


What version of the product are you using? On what operating system?
OS: Windows 8
APP: apt-cyg 0.57

Please provide any additional information below.
Mirror structures are changed, expected file setup.ini can't be found in mirror 
root, instead it located at architecture directory 
(http://XXXX/pub/cygwin/x86_64/setup.ini)
In my case I fixed the problem by changing these lines:
88:  mirror=http://mirror.isoc.org.il/pub/cygwin/x86_64
331: install=`cat "release/$pkg/desc" | awk '/^install: / { print $2; exit 
}'|sed 's/\/x86_64//g'`

What steps will reproduce the problem?
  1. copy apt-cyg source to cygwin's /usr/bin/
  2. apt-cyg install nano

What is the expected output? What do you see instead?
Expected:
  Found package nano
Actual:
  Package nano not found or ambiguous name, exiting

What version of the product are you using? On what operating system?
  apt-cyg .57 on Windows 7

Please provide any additional information below.

What is the expected output? What do you see instead?
i can specify or change my favorite mirror site directly.

What version of the product are you using? On what operating system?
cygwin 1.7.9-1, windows xp sp3.

Please provide any additional information below.

some files in the mirror ftp now use .tar.xz format, such as command 'pv'.

please enhance support for support .tar.xz file.

    echo "Unpacking..."
    cat $file | bunzip2 | tar > "/etc/setup/$pkg.lst" xvf - -C /

====>>>>>>  changed to 

    echo "Unpacking..."
    if [ $file == *.xz ]
    then
      cat $file | xz -d | tar > "/etc/setup/$pkg.lst" xvf - -C /
    else
      cat $file | bunzip2 | tar > "/etc/setup/$pkg.lst" xvf - -C /
    fi

  as e.g. fyi.

Working directory and mirror should be taken from setup.rc by default.

Now they are hard-coded to "/setup" and "ftp://mirror.mcs.anl.gov/pub/cygwin".

cygwin mirrors have changed their dir structure recently to have x86 and x86_64 
subdirectories

Please add a reinstall flag to install.

I had a package (tetex-bin) that wouldn't uninstall because tetex-bin.lst.gz 
was missing. And it wasn't possible to install it because it was listed in 
installed.db. The manual step in this case is to remove it from installed.db 
and install (and then uninstall), but it would be easier if there was a 
reinstall option.

Thanks!

What steps will reproduce the problem?
1. install 64 bit cygwin
2. download the utility as mentioned on the wiki
3. try to use it.

I had to apply the following patch to get it working:

       then
         echo Updated setup.ini

I changed the mirror just so that I use a more trusted server. Otherwise, the 
mirror in use does not matter.

The main problem is that it is looking for setup.ini and setup.bz2 in the wrong 
location.

If I include "x86_64" inside the mirror location itself, then it appends 
another "x86_64" when looking for actual package files, thus failing later.

Either ways, it fails and so I had to fix it in the above manner.

I was using 32 bit cygwin earlier and did not have this problem.
