Updating channel 'guix' from Git repository at 'https://git.savannah.gnu.org/git/guix.git'...
guix pull: error: aborting update of channel 'guix' to commit 6ca7b07a251739dfaefa639e74c01e3013c9454c, which is not a descendant of f13f0769688493271f43f31a016957355dbecb30
hint: This could indicate that the channel has been tampered with and is trying to force a
roll-back, preventing you from getting the latest updates.  If you think this is not the
case, explicitly allow non-forward updates.

I don't have reason to believe the channel needs to be rolled back, I 
assume something is wrong with the savannah copy of the repo, but don't 
know. Can someone confirm?

Thanks!
Jack
