I do a fresh install, update to latest 3.0.74, installed omv-extras, select OMV-Extras Testing Repo, select TS3.
Pluging is apparently installed and showed in the icon column,
My next step is to accep EULA, and wait several minutes, nothing changed and syslog show problems starting TS3, I reboot NAS and problem persist.
So I de-install pluging and wait if someone can help
