pkg - Wrong running kernel version

[Özkan KIRIK]

Hello,

I'm using the latest FreeBSD stable/12 branch.
pkg tool, detects wrong running kernel version.
the output is below:

# uname -U
1202504

# pkg add squid-4.13.txz
Installing squid-4.13...
Newer FreeBSD version for package squid:
To ignore this error set IGNORE_OSVERSION=yes
- package: 1202502
- running kernel: 1201522
Ignore the mismatch and continue? [y/N]: N

As you see above, pkg detected wrong kernel version. Why the uname -U and
pkg running kernel versions are different? How can I fix this problem?

Regards
