Hi Jeremy > I do not understand why bugs like this cannot get fixed even years after > several people have reported the same issue and the repro steps are clear
I understand this might seem frustrating, but the TL;DR is: Because it isn't as clear as it might seem Detail: As you see throughout the discussions many have tried to recreate it with those steps but it was not triggering for further debugging. Just to be sure I did try to recreate again in a new clean system (this time direct upgrades, no do-release-upgrade) upgrading X-B-F => no issues. I also rechecked the libseccomp.so files - always had only those belonging to the current installed version. As you can see the open question is either: a) find the details to the steps to really recreate this or b) finding out where the older files came from as they have in none of the case been part of the system that was upgraded from but from somewhere further in the past. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to libseccomp in Ubuntu. https://bugs.launchpad.net/bugs/1876486 Title: systemd breaks due to old libsecomp libs left on the system Status in libseccomp package in Ubuntu: Expired Bug description: Upgraded Ubuntu 18.04 to 20.04.
