[Touch-packages] [Bug 1876486] Re: Kernel panic booting after 18.04 to 20.04 upgrade
Hmm thanks Raphaël. So files were still around that were unowned, that really should not happen. Thanks for the exact file names. The files you had in your case were part of libseccomp2 2.3.1-2.1ubuntu4 which is what Ubuntu had in Bionic-release. libseccomp2 | 2.3.1-2.1ubuntu4 | bionic | But before you'd be able to upgrade to Focal (do-release-upgrade will otherwise block) that would even in Bionic be upgraded to 2.4.3-1ubuntu3.18.04.3 libseccomp2 | 2.4.3-1ubuntu3.18.04.3 | bionic-security | libseccomp2 | 2.4.3-1ubuntu3.18.04.3 | bionic-updates | On that upgrade these files would vanish. I've taken a Bionic system, downgraded to 2.3.1-2.1ubuntu4 and from there upgraded the package. The files went away as one would expect: root@b:~# ll /lib/x86_64-linux-gnu/libseccomp.so* lrwxrwxrwx 1 root root 19 Mar 1 2018 /lib/x86_64-linux-gnu/libseccomp.so.2 -> libseccomp.so.2.3.1 -rw-r--r-- 1 root root 280776 Mar 1 2018 /lib/x86_64-linux-gnu/libseccomp.so.2.3.1 root@b:~# apt install libseccomp2 Reading package lists...

[Touch-packages] [Bug 1876486] Re: Kernel panic booting after 18.04 to 20.04 upgrade
I've just encountered this issue myself, on a VM that started life as Ubuntu 16.04, do-release-upgrade to 18.04, then to 20.04, and now it fails to boot with a similar error: /lib/systemd/libsystemd- shared-245.so: undefined symbol: seccomp_api_get The only non-Ubuntu-standard stuff on this VM is some perl modules installed via CPAN, and none of those touch anything to do with Systemd, so I'm not sure why this is happening. I did see a post-install upgrade issue with the rkhunter package failing to find /usr/bin/egrep, but I ignored that issue and continued. I'm going to rollback, look for the lib involved, and see if I can remove it before retrying the do-release-upgrade -d to 20.04. -- 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: Kernel panic booting after 18.04 to 20.04 upgrade Status in libseccomp package in Ubuntu: Incomplete Bug description: Upgraded Ubuntu 18.04 to 20.04.
