This seems to be the culprit:
MarkInstall libqt5quick5-gles:amd64 < 5.15.10+dfsg-2 -> 5.15.13+dfsg-2 @ii umU Ib > FU=0 Installing libqt5gui5-gles:amd64 as Depends of libqt5quick5-gles:amd64 MarkKeep libqt5gui5t64:amd64 < none -> 5.15.13+dfsg-1ubuntu1 @un umN > FU It's not clear to me why this happens, but this is blocking libqt5gui5t64:amd64 from being installed which then later leads to hilarious conflicts. Likewise MarkDelete libcap2-bin:amd64 < 100:2.48-1 @ii mK NPb Ib > FU=1 seems wrong as well, the culprit for that is funny: 2024-09-24 18:26:04,453 DEBUG Found replacement libcap2-bin:i386 for libcap2-bin I am going to use this bug to track the 2nd issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2081864 Title: Upgrade from mantic to noble aborted.
