BSD version

[m_pahlevanzadeh]

I had 12.* and upgrade via freebsd-update -r 13.1 upgrade
after restart machine, I have the following system:

# freebsd-version 
12.3-RELEASE-p12
/root{104}# freebsd-update -r 13.1 upgrade
freebsd-update: Cannot upgrade from 13.1-RELEASE to itself

My problem is system knows me as 12.* such as :

# pkg search mldonkey
pkg: repository FreeBSD contains packages for wrong OS version: FreeBSD:12:amd64

How can I use new repository?

I suspect you didn't perform upgrade properly. Please read carefully https://docs.freebsd.org/en/books/handbook/cutting-edge/ and verify upgrade steps.

Note that 13.1 is EOL. You must upgrade to 13.2.

You likely ran freebsd-update install only once, for a major version upgrade it has to be run a total of three times. First one only upgrades the kernel, second run upgrades the userland and the third cleans up old stuff from the previous version.
