Hi,

Maybe it's a trivial issue but I followed the procedure on:

https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/updating-upgrading-freebsdupdate.html

Everything went well until the first reboot. I was able to ssh to the
system and then when I did freebsd-update install for the second time,
it started outputting a whole bunch of ELF related messages, like some
sort of 32/64 compatibility problem.

ELF interpreter /libexec/ld-elf.so.1 not found, error 8
Abort trap
/usr/sbin/freebsd-update: /bin/rm: Exec format error
ELF interpreter /libexec/ld-elf.so.1 not found, error 8
Abort trap
ELF interpreter /libexec/ld-elf.so.1 not found, error 8
Abort trap
/usr/sbin/freebsd-update: /bin/rm: Exec format error
ELF interpreter /libexec/ld-elf.so.1 not found, error 8
Abort trap

Now I tried to reboot and it won't even load in single user.

What gives?
