I managed to unbreak my system (in case anyone stumbles here looking for help) after reporting bug 2063219
Julian suggested installing libglib2.0-0t64_2.80.0-6ubuntu1_amd64.deb manually downloaded from the archive with dpkg, which I did. Then checked the debs in /var/cache/apt/archives/*.deb were only from the release upgrade (not from previous updates) by correlating with my /var/log/dpkg.log package update timings. sudo dpkg --install /var/cache/apt/archives/*.deb. # ran this twice sudo apt --fix-broken install. # this now runs successfully sudo apt update sudo apt dist-upgrade # to continue the broken mantic to noble upgrade liblxc-common 1:5.0.1-0ubuntu7 and liblxc1 1:5.0.1-0ubuntu7 have a colliding /usr/lib/x86_64-linux-gnu/lxc/rootfs/README sudo apt --fix-broken install. # resolved above by removing liblxc1 sudo apt dist-upgrade sudo apt install ubuntu-desktop^ sudo apt dist-upgrade After all that, it's "fixed".
