This is an umbrella task covering this problem and similar ones:

fatal: detected dubious ownership in repository at '/var/www/phorge'

In short:

• Sometime it's difficult to detect these issues since they are just suppressed without error logs
  • example: T15243
• Sometime it's not easy to fix it since the .gitconfig configuration of the webserver user is often not usable
  • example: T15281
• The documentation does not mention anything about that

Proposed fix

At the moment, this is the proposed solution:

git config --system --add safe.directory /var/www/arcanist
git config --system --add safe.directory /var/www/phorge

Please shared a comment if that works for you.

In case, we should add that in the installation instructions.

Possible Proactive Things

• D25236 Propose an update in the documentation to fix at system level
• D25148 Propose a patch to discover git errors from the console, instead of having them nowhere
• D25149 Propose a patch to allow the www-data user to read its own .gitconfig safe.directory stuff, so you can also fix without git config --system
