Hi Janos,
The best advice is probably making plans to get a KVM on the machine ahead
of time.
Barring this, if you already installed the world libs/sshd binary ... keep
your current ssh session active and restart the sshd daemon only to see if
that solves your problem.
Also ensure the config is proper and that all referenced paths resolve
correctly and anything referenced has been rebuilt against the new libs as
well.
If that fails, adding -vvv flags to the sshd upon startup would provide not
only you, but us further information as well.
Ultimately, I believe if you simply restart the daemon, the problem will
resolve itself.
~Paul
