Thank you Dani Llewellyn for pin-pointing the issue. I re-enabled and adapted that patch such that it doesn't conflict with the other ones and verified that gtk+3.0 builds successfully in Kinetic.

(It built on riscv64 because we skip the build tests there). My initial impression is that this is a reftest issue. The reftests are frustrating because dependency changes can lead to images that vary by as little as one pixel and fail the test. And upstream doesn't provide a precise list of dependency versions they are using either. https://launchpad.net/ubuntu/+source/gtk+3.0/3.24.34-3ubuntu1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gtk+3.0/+bug/1987304/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
