Ubuntu 19.10 to 20.04 upgrade getting stuck with fsck check

[Martin Goik]

The bug among with ist underlying system is being described in detail at https://askubuntu.com/questions/1260677/ubuntu-20-04-upgrade-getting-stuck-with-fsck-check.

The system is currently only bootable in rescue mode. As being described a regular boot shows an endless spinner following the grub menu stage during the boot process.

All packages are current to 20.04.

Additional info: On a fresh 20.04 re-install rebooting works fine based on the installation kernel 5.4.0-26. After upgrading the current 5.4.0-42 kernel fails to boot with the described behavior.

But after interrupting using the power-off button and choosing the still installed 5.4.0-26 installation kernel after power-on from the grub menu the boot process continues flawlessly.

I thus suspect a kernel related problem. Off-distribution kernels e.g. 5.7.9 don't work either.
