Public bug reported:
[ Impact ]
Due to an accidental removal of code in Ubuntu Studio Installer prior to
24.04's release, the removal mechanism that makes sure dependencies and
recommends of the metapackages of Ubuntu Studio (e.g. ubuntustudio-
audio, ubuntustudio-video, etc.) are marked as auto before an
autoremoval proceeds to remove them was erroneously removed. Therefore,
users wishing to customize their system after install cannot.
[ Test Case ]
Using Ubuntu Studio (full install on Oracular):
* Run Ubuntu Studio Installer
* Attempt to remove a metapackage by unchecking a metapackage and
clicking "modify installation".
In any flavor other than Ubuntu Studio
* Install ubuntustudio-installer
* Install a metapackage by checking a box using ubuntustudio-installer
* Attempt to remove said metapackage by unchecking the metapackage and
clicking "modify installation".
DESIRED BEHAVIOR: Metapackage and its recommends are removed.
ACTUAL BEHAVIOR: Nothing happens, returned to menu.
[ Problems that could occur ]
This entire mechanism relies on, and always has relied on, apt's
autoremove function. It will, therefore, also autoremove other packages
that are not part of those metapackages such as old, no-longer-needed
kernels that have been marked by the system as removable already. I
would argue that if a user were keeping their system maintained this
wouldn't be a problem.
However, this is safer than force-removing packages that are in the meta
that might be part of another meta since, if it's in the other meta, it
would not get autoremoved.
That said, this was tested with great success prior to initial
implementation and this is just bringing back an erroneous removal. I
would argue that any "regression" is the result of a poorly maintained
system or people are blindly marking packages as "auto" without thinking
about the repercussions.
