When doing reviews, I usually use the arcanist command “arc patch” to update my local git repository to match the Phabricator patch. This has been working for me for many months. For example, I recently tried to update my local repository by typing “arc patch D111254”. But today the command failed with the message:
Thanks for the help, Mehdi.
My problem turned out to be that there was something stale in my shell instance, which was many weeks old. When I exited the shell and re-invoked it, everything magically started working.
Glad it worked out in the end
