 | This page describes a complex and advanced use of Toolforge. It is not a recommended best practice and is not officially supported by the Toolforge administration team. |
To install a different package version, any other missing package, different Debian version or even a different Linux distribution you can use fakechroot environment.
You can create your fakechroot environment in my_env folder using:
$ fakechroot
(fakechroot) $ fakeroot
(fakeroot) $ /usr/sbin/debootstrap --variant=fakechroot stretch my_env
This will install package manager, some basic tools, commands and prerequisites, everything into your new fakechroot unit.
Once you created one, let's use it and play with it:
(fakeroot) $ chroot my_env
(chroot) $ apt install ffmpeg
...
Once you are happy with it, you can always leave using:
(chroot) $ exit
(fakeroot) $ exit
(fakechroot) $ exit
