Did you try to use svn? Something in lines

svn co https://svn0.us-east.freebsd.org/base/releng/12.2 /usr/src

(confessing: I=E2=80=99m lazy guy, and about a week or so ago I still =

I would just move existing /usr/src off the way (rename) and pull fresh =
new of the release you need (say, using svn command if git doesn=E2=80=99t=
 work on that machine for whatever reason).
