I've just faced this bug, which made the 18.04 to 20.04 upgrade fail. It seems that, after upgrading, DKMS tries to build LTTNG modules for the 18.04 kernel (4.15), which doesn't work.
A possible workaround is to remove this package before the upgrade, and reinstall it afterwards. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1900264 Title: package lttng-modules-dkms 2.11.2-1ubuntu0.2 failed to install/upgrade: installed lttng-modules-dkms package post- installation script subprocess returned error exit status 10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lttng-modules/+bug/1900264/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
