Hey!
I have Phabricator working together with Github. Everything is working except "Land to Github". I have to do it all the time manually.
This is the error:
```
Failed to allocate a workspace:
Command failed with error #128!
COMMAND
git fetch
STDOUT
(empty)
STDERR
Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
```
What can be the issue? If I execute `git fetch` via ssh on the machine, it works fine. Diffusion is also tracking the repo as expected.
Thanks!
