After trying to roll forward again I saw the output from ldconfig /lib/x86_64-linux-gnu/libseccomp.so.2.2.0 is not a symbolic link
Looks like I had duplicate versions of libseccomp2 lying around on my LD_LIBRARY_PATH dpkg -L libseccomp2 /usr/lib/x86_64-linux-gnu/libseccomp.so.2.4.3 So I deleted the ones in /lib/ and then upgraded systemd to the latest version. -- 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: New Bug description: Upgraded Ubuntu 18.04 to 20.04.
