Interesting! Feel free to email me at connor@repairtechsolutions.com.
I spent some time with the team looking at this issue and it seems that there is an issue with the Dropbox package not allowing it to install. The funny thing is that same error doesn't seem to be happening for Steam, I was able to install and update just fine with it. Hopefully the error log helps in this area because frankly we're stumped. Dropbox on the other hand, I've reported the issue and we'll work quickly to try and get it resolved
