Portainer App not starting after update to 1.5.0

Apps and Virtualization

I just updated the official Portainer App from TrueNAS App Version 1.4.28 (at least that is the latest version I could theoretically roll back to) to 1.5.0.
After this the app does not start anymore.
It tries to and then is stopped again.
Running docker logs <CONTAINER ID> shows 2026/01/02 08:50PM FTL github.com/portainer/portainer-ee/api/cmd/portainer/main.go:138 > failed creating file service | error="mkdir /data/certs: permission denied" a couple of times.

The only host mount is for Portainer data storage which has not changed.
I tried chowning the contents from root to apps although user and group config are set to 0 each but that didn’t change the message.

When I try to roll back I get:

The app currently is stopped but I don’t get a rollback button in the few tenths of seconds when the app is running.

Any ideas?

Oookay I got the app running again - I created a second folder with 777 premissions, pointed the host mount to that and portainer worked and created it’s files - with the same permissions as the old folder which made me suspect the topmost folders permissions.
I chown o+x <mounted folder and portainer worked again. I think this means that the app couldn’t see it’s own /data folder (in the container) anymore.

As the portainer process is running as root I do not understand why.

I do not think this permission change should have been needed - any idea why this happened anyone?
