I just upgraded my pc running my printer to Ubuntu 17.10 and now MatterControl shows me limited connectivity (orange icon) next to my sync login. Online I found that I have to downgrade my version of mono from 4.6 to 4.4.2 however when following the commands provided on the wiki 4.6.2.7 is still installed. Going through my update log I get the following error: W: Conflicting distribution: http://download.mono-project.com/repo/debian wheezy/snapshots/4.4.2 InRelease (expected wheezy/snapshots/4.4.2 but got wheezy).

Is there anyone with more experience with Ubuntu/linux (I only use it to run my printer) who can help me solve the issue; when opening the file: /etc/apt/sources.list.d/xamarin.list the contents are: "deb http://download.mono-project.com/repo/debian wheezy/snapshots/4.4.2 main".

Many thanks in advance.
