I have a vanilla FreeBSD 12.3-RELEASE-p6 (amd64) system. Upgraded to 12.4-RELEASE as follows: remote login via ssh freebsd-update upgrade -r 12.4-RELEASE freebsd-update install reboot remote login via ssh freebsd-update install now (after second install-run) remote login vi ssh is no longer possible Current solution: whilst still logged on, reboot again remote login via ssh is then possible again (at least when I tested this) Originally tested with FreeBSD 12.3-RELEASE-p6 on VMWare Fusion (on MacBook Pro with macOS Monterey 12.4), retested with a vanilla FreeBSD12.3-RELEASE install (installed from ISO-Image FreeBSD-12.3-RELEASE-amd64-dvd1.iso), same problem. This might bite all people who have remote systems without (remote) console access. Best regards Holger (not sure if this is similar to bug #41202)
