openssh upgrade breaks ssh login without reboot

[u/_supert_]

Just a warning. It seems last night's openssh upgrade broke login over ssh:

kex_exchange_identification: read: Connection reset by peer
Connection reset by 10.0.0.XXX port 22

Reboot solved. For a remote machine that's pretty annoying; I suggest you avoid upgrading openssh unless you have physical access or can otherwise reboot. Perhaps restarting the ssh daemon would be sufficient. I didn't try that.

yes. i had the same issue. Restarting the sshd solved it.

Same here. Restarting the service through the hypervisor terminal did the trick.
