freebsd stable - Dec 2018 - issue upgradning src

Hi,

I want to upgrade my 12.0-ALPHA8 to the latest release, yet I am unable to
update from source:

#pwd
/usr/src
#ls
COPYRIGHT               Makefile.libcompat      UPDATING                etc

#svn update
Skipped '.'
svn: E155007: None of the targets are working copies
#uname -r
12.0-ALPHA8

On the other hand - freebsd-update also fails: 
#freebsd-update fetch
Looking up update.FreeBSD.org mirrors... 2 mirrors found.
Fetching public key from update4.freebsd.org... failed.
Fetching public key from update1.freebsd.org... failed.
No mirrors remaining, giving up.

How can i upgrade to the lastest release of 12.0 without reinstalling the
system?

All best,
mjb
