In case anyone rebooted (like me) and ended up with a message like: "Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown- block(0,0)"
Just go to the grub menu, select Advanced Options > pick a previous kernel and boot, once you get the terminal, type: sudo dpkg --configure -a Or: Advanced Options > pick a previous kernel (in recovery mode), get a root terminal from the menu, run: dpkg --configure -a The upgrade process should continue. Once it's completed just reboot and the system should be updated. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to dbus in Ubuntu. https://bugs.launchpad.net/bugs/1968845 Title: Upgrade to 22.04 from 20.04 ends with dbus installation asking for a reboot Status in dbus package in Ubuntu: Confirmed Bug description: Upgrading on a virtual machine from 20.04 to 22.04. I have had this happen twice now, I got one upgrade done without this bug. Basically the package installation stops at dbus package asking for a reboot as it was unable to upgrade as dbus-daemon was running. And rebooting at this stage obviously will cause a non-functioning system. Added a screenshot of the upgrade window.
