Upgrade 11.2 -> 12.0 fall, rollback completed successfully. [SOLVED]

[jeltoesolnce]

Hello. When I tried to make upgrade, I got this messages:

chown 0:0 ///proc: Operation not supported
chmod 555 ///proc: Operation not supported

My /proc permissions are:

dr-xr-xr-x   1 root  wheel     0 13 дек.  19:26 proc

But freebsd-upgrade did worked and after it I got message (uname -a) about version 12.0-RELEASE. But X did not run and some libraries did not install. Rollback was been correct.

chown 0:0 ///proc: Operation not supported
chmod 555 ///proc: Operation not supported

Those messages are harmless, do not pay attention.
X stuff is not a part of the base system, you have to upgrade your packages.

# pkg-static install -f pkg
# pkg upgrade

Also, before performing that, make sure you rebooted and ran freebsd-upgrade install a couple of times – as it's suggested.
