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

[Paul Mars]

Hello borgdylan,

I understand the similar issue in arch was caused by glib2 2.80 being
built against a version of util-linux not yet published. I understand it
was fixed when `util-linux-2.40rc2-1` was made available.

In our case, I checked that our current version of glib2
(https://launchpad.net/ubuntu/+source/glib2.0/2.82.1-0ubuntu1) was built
with util-linux 2.40.2-1ubuntu1 (current version available since
2024-08-21).

I tried an upgrade from noble, after verifying I had libmount
2.39.3-9ubuntu6.1 and glib2.0
[2.80.0-6ubuntu3.1](https://launchpad.net/ubuntu/+source/glib2.0/2.80.0-6ubuntu3.1).
The upgrade went fine, libmount 2.40.2-1ubuntu1 was installed, the
previous version removed and I could not see any error.

How did you upgrade? From which series did you upgrade? Did you run apt
update && apt upgrade before?

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.
