Newb here. I'm following along with the Beginner OMV Raspberry Pi installation video, installing OMV 4 on a Pi 4. I'm 45 seconds from the end with no problems until the part where Shellinabox gets set-up under Services. As soon as I click on Shellinabox, I get "Failed to execute XPath query '//services/shellinabox'." After I click OK, I can still enable Shellinabox, but I get the same error when I click Save, and it doesn't tell me to apply the changes, as it should. Any suggestions? Doesn't look like it's essential to NAS operation, but I'd like to know why it failed, just the same.
I got an error when initially installing this (and Docker), but since the UI showed they'd both been installed (when previously they hadn't been), I ignored it (and didn't write it down). Docker enables without any problem.
Thanks for any help.
