I've encountered the same problem. I received message for 'sgml-base' and 'linux-image-5.0.0-13-generic':
""Could not install 'sgml-base' The upgrade will continue but the 'sgml-base' package may not be in a working state. Please consider submitting a bug report about it. triggers looping, abandoned" Followed by the same message for 'linux-image-5.0.0-13-generic'. When the upgrade from 18.10 to 19.04 finished it showed: "Could not install the upgrades. The upgrade has aborted. Your system could be in unstable state. A recovery will run now (dpkg --configure -a)" Other than the package involved this seems a duplicate of https://bugs.launchpad.net/bugs/1823004 In looking at the crash logs they lead to the same conclusion as in https://bugs.launchpad.net/ubuntu/+source/ubuntu-release- upgrader/+bug/1823004/comments/5 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1823272 Title: package sgml-base 1.29 failed to install/upgrade: eindeloze triggerlus; afgebroken To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sgml-base/+bug/1823272/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
