Hello Joshua, or anyone else affected,

Accepted gtk4 into noble-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/gtk4/4.14.5+ds-0ubuntu0.1 in a few
hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
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-
noble to verification-done-noble. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-noble. 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
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)

Title:
  [SRU] libgtk-4-1: Missing dependency libgles2 on Noble

Status in gtk4 package in Ubuntu:
  Fix Released
Status in gtk4 source package in Noble:
  Fix Committed
Status in gtk4 source package in Plucky:
  Fix Released

Bug description:
  [ Impact ]

  * libgtk-4-1 has an implicit dependency on libgles2. GTK4 apps running
  on containers like WSL, where the installation doesn't come with all
  required dependencies upfront, crash immediately due the missing
  dependency.

  * gtk4 version 4.14.5 makes that dependency explicit, so libgles2 will
  be installed automatically when libgtk-4-1 is installed.

  
  [ Test Plan ]

   Test Case 1 - gtk4-demo on containers
  --------------------------------------
  * Setup an Ubuntu 24.04 container (Ubuntu on WSL instance, LXD or docker, as you wish).

  * Make sure it doesn't contain the libgles2 package already installed
  (`apt list --installed | grep libgles2` output should be empty)

  * Update apt cache and install gtk-4-examples and try running
  gtk4-demo.

  With previous versions of GTK4 it fails to launch due libgles2.so not
  found. With the proposed patch libgles2 will be automatically
  installed and gtk4-demo will just run without crashes.

  
  [ Where problems could occur ]

   * Many of the default Ubuntu desktop apps use GTK4. A serious enough
  regression could severely break the Ubuntu Desktop.

  
  [ Other Info ]

  gtk4 is included in the GNOME micro release exception since it is part
  of GNOME Core

  https://documentation.ubuntu.com/sru/en/latest/reference/package-
  specific/

  The issue was first discovered while doing the WSL Import and run test
  for 24.04.2 documented in the ISO tracker. gtk4-demo failed to launch
  due to missing the library for libGLESv2 (so would any other GTK4 app
  running on WSL or LXD containers, for example).

  Installing libgles2 fixed the issue.
