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.
