This was all while installing this and that dependency and troubleshooting it. Docker was a complication I didn’t want to learn yet.
And then tinytinyrss moved to docker only which forced my hand. I can say installing Docker and Portainer (as someone who prefers a GUI more than command line) has made self hosting so much easier for me, and hugely reduces the need to think about dependencies.
It’s likely those images haven’t been updated in the 8 hour period in which watchtower checked. Daily or weekly update schedule should suffice.
