installation issue on debian 9.4 about virtualmin-install

[jcameron]

Oh wow, another network config format!? Is this the default on Debian 9?

[swelljoe]

Did Debian switch to netplan, too!? This is the same exact error we get on Ubuntu 18.04 systems with netplan...I haven't seen it on Debian, though. But, if they've changed the network config system, it'll be the same solution (which is ongoing).

[ahyear]

ok, so what I've see is that my network conf is not in /etc/network/interfaces but in /etc/systemd/network/50-default.network
so that is why it can't find the file.

is the install script adapted for systemd netxork configuration?

[swelljoe]

I don't know. Is that the old style config file, or something else (like netplan)?

Can you post the contents of that file?

[ahyear]

I removed al sensitive informations

Yeah, looks like yet another network configuration system. Good fun. This is gonna take a while. We still haven't quite finished netplan (Ubuntu's newfangled thing...I wish they'd gone the same route as Debian, as we now have even more things to support).

[ahyear]

As it is said on the article I posted this seems to be the new standard... I will check if I see the same configuration in Ubuntu (as it is normally based on Debian )

[ahyear]

I reinstalled my serveur on ubuntu 18.04 and I have the same configuration as Debian ( /etc/systemd/network) so I guess it is not a netplan configuration that has to be adapted but a systemd one.

Il my configuration, /etc/netplan/ is present but empty. only /etc/systemd/network/ as network configuration in it.

I can confirm that issue is still not fixed... Netplan comes by default, and on cloud VPS, it configures networking automatically, it's a real trouble to change it, especially with IPv6

What Webmin version is getting installed?

[acosonic]

I've done apt update & apt upgrade (nothing to install), then installed from

wget http://software.virtualmin.com/gpl/scripts/install.sh

[iliajie]

Is Webmin version installed 1.900? Version 1.920 has netplan fixes.

[acosonic]

I've added
deb http://download.webmin.com/download/repository sarge contrib

manually, howver, seems that
wget http://software.virtualmin.com/gpl/scripts/install.sh

Doesn't add it to the sources list, but it rather adds some old repo, which doesn't work...

[acosonic]

Also uninstalling (from the above repo, doesn't work, which is probably a different issue...

Yes, the script at
http://software.virtualmin.com/gpl/scripts/install.sh

Adds following repos:

deb http://software.virtualmin.com/vm/6/gpl/apt virtualmin-bionic main
deb http://software.virtualmin.com/vm/6/gpl/apt virtualmin-universal main

Instead of:
deb http://download.webmin.com/download/repository sarge contrib

and installed webmin is: 1.900

[swelljoe]

Closing this as no longer relevant, since the Virtualmin 7 installer has been released, and Debian 9 reached EOL. I think we install OK on Debian 10 and 11, and I think we safely handle the newer network config system (I don't know if it's fully supported, but I'm pretty sure we don't break it).
