I have blocked on this issue for days, and tried a lot, googled a lot, but didn't get valuable info.
I have done all phabricator config. And there weren't issue for diffusion. I can rum arc diff correctly, but when I do arc lan, this issue came out.
Also I can play git init --bare, and then git pull, push correctly. the git version is 2.7.2.
and the log with --trace flag is blew:
~/phabricator_test/test $ arc land --trace
ARGV '/mnt/data/arcanist/bin/../scripts/arcanist.php' 'land' '--trace'
