Sorry for this confusion about my last comment.
The installation issue is clearly not related to Cannonical and I apologize for this.

However, I finally managed to have a Ubuntu 20.04 running on my system with some tricks. Then I picked the kernel from here: https://launchpad.net/ubuntu/focal/s390x/linux-image-5.4.0-94-generic/5.4.0-94.106 as the bug suggests, installed and rebooted. So now I am running kernel:

root@a35lp66:~# cat /etc/os-release
NAME="Ubuntu"
VERSION="20.04.3 LTS (Focal Fossa)"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu 20.04.3 LTS"

root@a35lp66:~# uname -a
Linux a35lp66 5.4.0-94-generic #106-Ubuntu SMP Thu Jan 6 23:57:26 UTC 2022 s390x s390x s390x GNU/Linux

But I am missing the sysfs attributes
/sys/devices/ap/cardxx/max_msg_size
for all crypto cards. So is patch
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=bd39654a2282c1a51c044575a6bc00d641d5dfd1
really integrated into this kernel ???
