Hello Alfonso, or anyone else affected,

Accepted plymouth into oracular-proposed. The package will build now and
be available at

few hours, and then in the -proposed repository.

Please help us by testing this new package.  See

to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
oracular to verification-done-oracular. If it does not fix the bug for
you, please add a comment stating that, and change the tag to
verification-failed-oracular. In either case, without details of your
testing we will not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in

Bug description:
  plymouth does not display text on Ubuntu Core 24, this is because of a
  regression introduced by
  https://gitlab.freedesktop.org/plymouth/plymouth/-/commit/544e62ac41a490f04d8e6b4e85f8b9fa1171b0cc

  This was later fixed by:
  https://gitlab.freedesktop.org/plymouth/plymouth/-/commit/792fe7474a02a1facacdd52e0dcf9053da4b1f6e

  The patch is now in plucky but needs to be backported to noble and
  oracular (TPM backed desktop systems could be affected).

  [ Impact ]

  Users do not see messages about boot status that were printed in the
  past in Ubuntu Core systems.

  [ Test Plan ]

  To reproduce: run UC24 on a qemu VM adding "splash quiet" to the
  kernel command line from the grub menu. If the system has the bug, no
  message will be displayed in the bottom part of the display while the
  splash screen is shown.

  [ Where problems could occur ]

  The patch comes from upstream and it affects the label-freetype
  library, which is used only on UC/hybrid systems, so there should be
  no impact for regular desktop users.

  On UC, if something goes wrong then maybe plymouth could crash and we
  would end up with no splash, but the fix is prettly simple and comes
  from upstream so chances of this happening are small.

  [ Other Info ]

  None at the moment.
