I've successfully upgraded OMV from 1.19 -> 2 -> 3.0.92.
I was going to upgrade to 4, but received the following error when I ran omv-update as well as omv-release-upgrade:

I've seen similar issues reported for earlier versions, but I didn't see anything for this error for OMV3/Jessie.
Any pointers would be greatly appreciated.
