Solved match src directory according new kernel.

[m_pahlevanzadeh]

I have the following system:

/usr{149}# freebsd-version 
12.3-RELEASE-p8
/usr{150}# uname -r
13.0-RELEASE-p13

I removed /usr/src .
Now I want to sync all of system according to my new kernel.
How can I sync?

You have to need get via git clone -b releng/12.3 https://git.freebsd.org/src.git /usr/src at first.

The kernel is from releng/13.0, note that 13.0 is actually older than 12.3, it's also a version that's end-of-life. Upgrade to 13.1 if you want to upgrade to 13. You do not need to upgrade to 13.0 first in order to upgrade to 13.1. You can upgrade directly to 13.1.
