Hi, I probably did something wrong with the portainer docker change I don't have the right certificates anymore. I also had a time problem but that has now been solved The notifications are Err:6 https://openmediavault-plugin-developers.github.io/packages/debian shaitan InRelease Certificate verification failed: The certificate is NOT trusted.

They have been ignored, or old ones used instead. I've spent hours and hours reading threads and trying to recover but it doesn't work Can someone try to get me back on the right path ? OMV still runs fine just no docker anymore and no updates :( Regards Henri
