Hello, I have/had an 11.3 system which I attempted to update to a current version. I was updating minor versions step by step and ended up with 11.4. The upgrade attempt to 12.0 from 11.4 failed, I found previous posts related to that issue. I was able to load the old kernel, using option 5 at the boot menu and restoring /lib, /user/lib files to get commands working, as well as freebsd-update from an 11.4 usb boot image.
