Depending on your system and your personal preferences the installation procedure may vary. Below is a description of the various installation methods available. You can download the packages here.
We provide 4 packages for linux systems. deb, rpm, an aur package and a linux installer. You can get them here.
The aur package can be installed using any AUR helper.
This is the package for Debian-based distros (Debian, Ubuntu, Mint, SteamOS, etc.).
Download the gaiasky_linux_<version>.deb file and run the
following command. You will need root privileges to install a deb package in
your system.
$ dpkg -i gaiasky_linux_<version>.deb
This will install the application in the /opt/gaiasky/ folder
and it will create the necessary shortcuts.
In order to uninstall, just type:
$ apt remove gaiasky
We also provide an AUR package called gaiasky. You can install it easily with any tool capable of accessing AUR, for example yay.
$ yay -S gaiasky
This is the package for RPM-based distributions (Red Hat, Fedora, Mandriva, SUSE, CentOS, etc.)
Download the gaiasky_linux_<version>.rpm file and run the
following command. You will need root privileges to install a rpm package in
your system.
$ rpm -ivh --nodigest gaiasky_linux_<version>.rpm
This will install the application in the /opt/gaiasky/ folder
and it will create the necessary shortcuts.
In order to uninstall using yum (replace by dnf if needed), just type:
$ yum remove gaiasky.x86_64
We also provide a Linux installer (here) which will trigger a graphical interface
where you can choose the installation location and some other settings.
Download the file gaiasky_unix_<version>.sh to your disk.
Then run the following to start the installation.
$ ./gaiasky_unix_[version].sh

installation folder.
Two windows installers are available for 32 and 64-bit systems here.

A gaiasky-<version>.tgz package file is also provided. It will work
in all systems but you need to unpack it yourself and create the desired
shortcuts.

As of version 2.1.0, Gaia Sky offers an automated way to download all data packs and catalogs from within the application. When Gaia Sky starts, if no base data or catalogs are found, the downloader window will prompt automatically. Otherwise, you can force the download window at startup with the -d argument. Just select the data packs and catalogs that you want to download, press Download now and wait for the process to finish.
You can also download the data packs manually here.
