Thanks for the data Matthieu! Hmm, that is indeed the "old & broken" style that should be (and is for qemu-block-extra) fixed in 5.1+dfsg-4ubuntu2.
... Packaging: - d/qemu-system-gui.*.in is gone in the packaging as intended. Binary Package: $ apt install qemu-system-gui $ dpkg -l qemu-system-gui ii qemu-system-gui:amd64 1:5.1+dfsg-4ubuntu2 root@h:~# ll /var/lib/dpkg/info/qemu-system-gui* -rw-r--r-- 1 root root 396 Nov 30 11:33 /var/lib/dpkg/info/qemu-system-gui:amd64.list -rw-r--r-- 1 root root 463 Nov 24 10:16 /var/lib/dpkg/info/qemu-system-gui:amd64.md5sums => no maintainer scripts anymore (as intended) So - as with the former issue - what is failing is the old packages prerm of 1:5.1+dfsg-4ubuntu1. I found in a discussion (thanks Juliank) why this isn't an issue with qemu-block-extra (which is what this was first found and fixed for) and can resolve it in a coming update. ** Changed in: qemu (Ubuntu) Status: Incomplete => Triaged -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1906245 Title: qemu-system-gui 1:5.1+dfsg-4ubuntu2 fails to upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1906245/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
