Cannot update, upgrade or install plexserver

Hi,

I have been using OMV for a year or so now and its been running great. I used an Dell optiplex FX160, a 16gb ssd, one internal 2tb hard drive and an external 5tb hard drive to get my file server going. I replaced a router based solution because I was tired of the unreliability. I managed to get the optiplex to idle around 12-15watts and it runs everything i need it to!

I have been trying to install plex and run into some errors, so I thought maybe I just update and upgrade to the latest omv version, but also ran into some issues.

When trying to upgrade or update I run into an issue with this repository:

W: Failed to fetch http://download.mono-project.c…ain/binary-amd64/Packages 404 Not Found [IP: 52.84.144.126 80]

How do I update the location of this package so it won't fail?

yes that is what I ended up doing thanks. I ran into other issues and just ended up wiping the install and starting with fresh omv 3+ install.
