This is an old OMV5 where I I was running out of space and hadn't kept it up to date.
In another thread related to my migration to OMV6 it was suggested that I should always apply updates and that the updates will take up no more space than the current versions.
Anyway perhaps I should have left well alone but the update took away all the current versions then started installing the newer versions and failed...
I've read that the omv-extras repo is moved to github, but can't figure out how to fix this.
I tried installing omv-extras from deb on github, but it failed saying dependency of openmediavault was not found
now any attempt to use apt gives me this error about the repo...
Reading package lists... Done E: The repository 'https://dl.bintray.com/openmediavault-plugin-developers/usul buster Release' does not have a Release file. N: Updating from such a repository can't be done securely, and is therefore disabled by default. N: See apt-secure(8) manpage for repository creation and user configuration details. ERROR: Command 'omv-aptclean' returned non-zero exit status 100.
How to fix so I can fire up the dockers and portainer again?
