As per T1519#27966, permission issue exists regarding the staging area.
for that particular instance, the staging area set for the webapp repository is indeed using an ssh://git@forge.softwareheritage.org access.
Possibilities so far:
- Do we use an https url instead (that's what we did for the git repositories of the swh-environment for example)
- Do we use arc's `--skip-staging` flag as mentioned by the author (thus updating the wiki page for that)?
- Disable the staging area (i'm not sure it's really used so far)
