Public bug reported: After performing the release upgrade from 19.4 to 19.10, my system is no longer booting.
After unlocking the disk encryption, the system begins loading and freezes with: ''' aufs aufs_fill_super:920:mount[3405]: no arg overlayfs: missing 'lowerdir' ''' I was able to add initcall_debug to kernel args at boot time and somehow it gets past the error and boots to terminal login prompt only - still no graphical UI. Please help!
