I had a similar issue upgrading from 22.04 to 24.04 (I think I hit ctrl-C for a similar reason, to discard a shell command I was in the middle of typing). After hitting ctrl-C I ended up in a weird state where roughly half of the characters I typed made it through and half didn't (didn't even get echoed)... eventually the process hung indefinitely.
I don't have any logs because I made the bad decision to reboot at this point; some aspect of GRUB config was in a broken state, which sent me down a path that eventually ended with re-imaging the box. Just wanted to emphasize that this is a thing that can happen very easily and leave the system in a delicate state. Seems bad. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2067318 Title: Hitting Ctrl-C in the dpkg config conflict interactive sub-shell aborts the upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/2067318/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
