Difference between freebsd-version -ku and uname -KU

[Jacques Foucry]

Hello all,

I have a strange diffence between the result of freebsd-version -ku command:

freebsd-version -ku
12.2-RELEASE-p3
12.2-RELEASE-p3

and
uname -KU
1202000 1201000

As a result, pkg always complain when I want to install a new pkg (comming
form my poudriere).

What could be involved in this difference?
How can I solved that?


Thanks for you advices
