Hi,
I tried to upgrade FreeBSD fom 11.2 to 12.0 release version. everything went well. I installed it and reboot the machine and I could ssh login into it after reboot. Then I closed the ssh session (before second reboot). Then when I wanted to login via ssh again, it didn't work! This is the log message via ilo:
Code: 
Performing sanity check on sshd configuration.
ld-elf.so.1: Undefined symbol "compat20" referenced from COPY relocation in /usr/sbin/sshd
/etc/rc: WARNING: failed precmd routine for sshd
I continued to complete the upgrade with last freebsd-update install and second reboot, but the problem is still there. Should I rollback the upgrade? I would appreciate any help.
thanks.
 
Thread softly. The FreeBSD 11.2 and FreeBSD 12 are now mixed up. If care is not taken you might have to do a clean install.
Thanks cpm@, I can now see that FreeBSD12 has matured (p10) enough to replace FreeBSD11.3. When have only upgraded to FreeBSD11.3 from 11.2 few days ago.
 
Yes, the upgrade process was interrupted somehow. Thank you for your help. I made a pretty clean install again.
