I did a apt full-upgrade, which yes I know is not recommended. After doing that command I noticed it said it was removing the openmediavault package, and sure enough, after it was done, openmediavault was gone. When I tried to reinstall it, I get this message:
I looked into downgrading again, and it seems like it can end up being even more unstable than the original full-upgrade.
I also noticed there's an alpha version for OMV version 6, would that work on my version of Debian?
