[Error] DPkg::Pre-Invoke 'umount /var/log/journal' error on Ubuntu & Debian images

[fossrob]

Describe the bug
A previous fix #123 seems to have introduced a problem with other DEB based distributions. Installing packages or applying updates fails with an error:

umount: /var/log/journal: no mount point specified.
E: Problem executing scripts DPkg::Pre-Invoke 'umount /var/log/journal'
E: Sub-process returned an error code

Removing /etc/apt/apt.conf.d/00_distrobox stops the error from occurring.

To Reproduce

• Create and enter an Ubuntu 20.04 distrobox
• Perform a sudo apt update; sudo apt install -y sshpass

Expected behavior
The package installation proceeds without error.

Logs
apt.log
distrobox-enter.log
docker.log

Desktop (please complete the following information):

• OS: CentOS
• Version 7

Additional context
Using the latest version: distrobox: 1.2.12

Hi @edserhub
seems like it is because /var/log/journal was not mounted during the container setup
can you post a log of

docker logs ubuntu

To check why it was not mounted?

(or simply check on your host if /var/log/journal exists in the first place 😄 )

A fix is incoming for it 👍

Hi @89luca89

Thanks for the response!

Ahh /var/log/journal does not exist on the host. It's a fairly standard CentOS 7 installation. At least, there's nothing that's been customised around systemd / journald.

Perfect that's what I was expecting 😄

Pushed right now a fix in: 77d6a65

Should work now, you can expect the fix to be part of the next release 👍

Amazing! 🙌🏻 I can confirm that 77d6a65 solves the issue for me. Thank you! 😊

Glad it's fixed, thanks for the report!
