Strange behaviour of lubuntu-grub-theme when purging it from the system
Open, NormalPublic

Description

In Lubuntu 20.04 the package lubuntu-grub-theme is part of the installation. In theory, it contains a theme for Grub. But in practice, I never saw it. Apart from that, the package may be unnecessary for

  • users who use another bootloader
  • users who don't have a multiboot and don't see the grub menu
  • users who prefer the old style
  • users who prefer another grub-theme

Unfortunately, it is not easy to purge the package:

~$ LANG=C apt -s purge lubuntu-grub-theme            
NOTE: This is only a simulation!
      apt needs root privileges for real execution.
      Keep also in mind that locking is deactivated,
      so don't depend on the relevance to the real current situation!

The following package was automatically installed and is no longer required:
  grub2
Use 'apt autoremove' to remove it.
The following packages will be REMOVED:
  lubuntu-desktop* lubuntu-grub-theme*
0 upgraded, 0 newly installed, 2 to remove and 1 not upgraded.
Purg lubuntu-desktop [20.04.6]
Purg lubuntu-grub-theme [20.04.2]

I would expect, that only the package lubuntu-grub-theme is removed. But it removes also lubuntu-desktop and marks grub2 as no longer required.

I'm not sure what problems are to be expected when removing the package lubuntu-desktop. But removing grub2 (e.g. with sudo apt autoremove) doesn't look like a good idea.

Event Timeline

apt-ghetto added a parent task: T100: Lubuntu 20.04.

Fixed it in D91. Testing required.

The_LoudSpeaker triaged this task as Normal priority.

There's no reason this should happen-nor would I think this would happen. I doubt this would probably happen but yeah, testing required.
