MR1100 Firmware Update Issue

I am literally in the same boat as everyone else here, same model, same firmware, same everything including this error.

I had actually been getting this error for a few months but broadly the internet was still usable so I didn't take the time to investigate however the last few days the internet has been bad to the point that it's affecting my ability to work from home. What exactly needs to happen here for the updates to work? Seems like it would be pretty straightforward for a company that has been making networking devices for over 20 years.
