Debian 11 - error while installing on lxc (/ispconfig.ai.php:15)

Hello I'm trying to install ISPConfig on Debian 11.
Type of machine is lxc on Proxmox. I was trying to install using https://www.howtoforge.com/ispconfig-autoinstall-debian-ubuntu/
Output log is:
```
18.01.2022-14:10:59 - /ispconfig.ai.php:15: [ERROR] Exception occured: ISPConfigOSException -> Installing packages failed.
```

I was trying with flags --no-quota and even --debug not showing any other output.
php-cli is also set to 7.4

 

Install on Proxmox virtual machine instead of on lxc container. That should work better.

 

Is there any future issues to not to use it on LXC ?

 

Thank You @till
Is there any way to avoid this warning while installing ISP Config from script to get to end configuration ?

 

What warning?

 

In short, it is not easy to install ISPConfig server in an LXC due to certain limitation, thus if you don't know how to handle the errors in LXC (which can occur again, and again, and again... may be endlessly) you shouldn't be using it and instead should create and use VM on the PVE to install ISPConfig server. It is more stable and reliable running any ISPConfig server that way.

 

Maybe there is bug in auto installer, output informing that is non-free packages is added to sources.list but it doesn't.
After manual adding installation process runs further.

 

@Th0m
You need /etc/apt/sources.list ? Content is:

Code:

deb http://ftp.debian.org/debian bullseye main contrib
deb http://ftp.debian.org/debian bullseye-updates main contrib
deb http://security.debian.org bullseye-security main contrib

 

Yes that is the reason. If non-free or contrib is already added then the regex fails and the second one will not be added.

 

Maybe this commit solves it: https://git.ispconfig.org/ispconfig...mmit/473feb1fad51c8d6b1aa3b006b12abc43db338bb
