As per topic, after upgrading, the upgrade otherwise completed successfully but the plugins page shows usul plugins installed and the usul plugins listing despite all the plugins per dpkg show as being the shaitan versions and working.
ii openmediavault 6.0.11-1 all openmediavault - The open network attached storage solution
ii openmediavault-keyring 1.0 all GnuPG archive keys of the OpenMediaVault archive
ii openmediavault-omvextrasorg 6.0.7 all OMV-Extras.org Package Repositories for OpenMediaVault
ii openmediavault-sharerootfs 6.0-3 all openmediavault share root filesystem plugin
ii openmediavault-snmp 6.0-4 all openmediavault SNMP (Simple Network Management Protocol) plugin
ii openmediavault-zfs 6.0.5 amd64 OpenMediaVault plugin for ZFS
So, technically a cosmetic issue but kinda afraid of trying to install anything off the listing in case it starts to try to do something catastrophic. Very odd.
