Public bug reported:
Ubuntu 22.04 system connecting to an Oracle Linux v8 host. The
following error occurs regardless of the the MACs specified (or not) in
sshd_config:
Corrupted MAC on input.
ssh_dispatch_run_fatal: Connection to XX.XX.XX.XX port 22: message
authentication code incorrect
Presumably, this may happen on any RHEL v8 variant. Note that connecting
to Enterprise Linux v7 work as well as other Ubuntu hosts. Downgrading
to previous version of openssh-client fixes issue.
apt install openssh-client=1:8.9p1-3
** Affects: openssh (Ubuntu)
