[Bug 2081684] Re: Things depending on libmount1 complain MOUNT_2_40 not found

[Dylan Borg]

Dear Mr. Mars,

Thank you for your reply.

I had upgraded directly from noble a day after the oracular beta was
released.

I started the process using "do-release-upgrade" (due to past issues
with the graphical updater) but for some reason, my lock screen
triggered (I should have ran the upgrade in a frame-buffer tty) and I
got locked out. I ended up switching to a tty and ran "kill -9 -1" to
stop the now un-monitorable process. I then resumed the upgrade using
"apt full-upgrade" till completion. For some reason it did not remove
the old t64 package for libmount1 which did not have a 2.40.2 version.
When I tried to repeatedly run "sudo apt install --reinstall libmount1"
I saw a message that the package contents were getting replaced by the
2.39.3 version instead of using 2.40.2.

Title:
  Things depending on libmount1 complain MOUNT_2_40 not found

Status in util-linux package in Ubuntu:
  Incomplete

Bug description:
  I have upgraded to the oracular beta yesterday on my home machine.
  After upgrading I started to notice errors issued by libgio that
  MOUNT_2_40 could not be found despite having libmount1 2.40.2
  installed as part the upgrade.

  On reboot I noticed that gdm no longer starts, and networking is
  broken. Even running nmcli in a tty fails with the same complaint.
  Loggin in on a tty using username and password still works but the
  system is broken.

  I have tried using a live environment and chrooting to reinstall
  libmount1, util-linux and libglib2.0 and libc6 packages as recommended
  on the arch forums (only arch users seem to have encountered this
  before me). The reinstalls were successful but the error message did
  not go away when I tried to run nmcli or other libgio using programs.

  Please give this a look since it might break many people's machines
  trying the beta like I tried to do.
