Hi, today I was trying to upgrade from 3.0.99 to 4 via SSH omv-release-upgrade but it won*t work.
bevor that I removed all non compatible plugins including OMV-extras plugin.
after entering the command omv-release-upgrade i got the blue screen with the message that all non-compatible plugins are deleted, I said "yes",
this is the error message in SSH.
Do you have any ideas?
