Describe the bug

Installed Outline on a fresh YunoHost install. It failed to connect to the redis instance.

Fix

I was able to fix it by changing REDIS_URL=redis://localhost:6379 to REDIS_URL=redis://redis:6379, as suggested in the Outline repo.

I am not sure if the default should be changed in this repo.

Reporting here for visibility if other YunoHost users run into this. Feel free to close, it is resolved for me.

Thanks for the report.
I will check and see if I need to change the repo as per your recommendation. Do you have any specificities about your Yunohost instance ?

Turns out its because redis wasn't running! I think this needs to have redis-server added to [resources.apt] in the manifest. I assume most other folks already had another app dependent on redis, so it was running.

Changing the URL was enough to trick it enough to have Outline run briefly, but it crashed as soon as I tried to update a page.

I fixed it by installing nextcloud which requires redis, and verified that the redis service was running. Outline is happy now (with original .env config).

Very good catch thanks.
This is probably something that went wrong when transitioning to the package v2 version.
I do not understand why the CI didn't catch that bug though !
I will push a corrective action
