Hi, I confirm the very same issue here. I've found another "solution" (if exchanging your ssh-keys is an option for you): Just create new keys with ssh-keygen and push them with ssh-copy-id to your target hosts. This works for me (but is for sure a nuisance when you have lots of hosts to feed the key with.
I've got a hint that the linked libssl3 might have caused the issue. In my case the switch from 2022-06-16 08:37:01 status installed libssl3:amd64 3.0.3-8 (which works) to 2022-06-23 10:54:50 status installed libssl3:amd64 3.0.4-1 which produces the error seems to be responsible. Hope this shades some light into this issue Andreas. -- http://fam-tille.de
