I will mention I searched on the forum for any information to resolve the "openmediavault : Depends: jc but it is not installable" error as I thought this could help to resolve the issue without taking up too much more of your time.
This led me to a thread by a user Kvlar on July 14th, 2025, who you assisted at the time.
Attempting to run "apt-get install jc" resulted in the same error as that user, Package jc has no installation candidate.
Running the dpkg --get-selections | grep hold resulted in the same no output.
Following on that thread, I ran omv-salt deploy run apt to no avail. 13 succeeded, 3 changed.
Re-running the apt-get for jc resulted in the same no installation candidate.
The user then said they reinstalled from the ISO and this resolved their issue, but mine has continued to plague me through 3 total installs from ISO, using a fresh download of the ISO each time.
I believe it's probably pertinent that I mention I did not install OMV whilst connected to a network, as I am forced to run via WiFi (I'm sorry, I know, I'm sorry, homeowner's rules, not mine, I'm sorry).
Running omv-upgrade results in the below:

I assume at this point it's likely a broken mirror or something.
Searching broken mirror leads me to other posts, but I'm struggling to find relevant posts. Probably just a user error with an unfamiliar search tool
Any thoughts on what to do next?
Please, do tell me if I followed the wrong path. I'd love to understand more.
