Oh I didn't realize Ubuntu 20.04 has a version of libc that's a little too old for that. You will need to try an older kernel version that's still newer than the 5.8.0 that caused this bug. Maybe try:

  https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.10.56/amd64/

Also the "invalid signature" problem I think is caused by Secure Boot. Try disabling Secure Boot in your BIOS.
