Description of issue: When trying to start, above error appears.
I’ve crossed similar errors topics on this forum, but everytime it seems the user only posted his error and never came back when asked questions 
I’ve checked config file. Line 3 is indeed <system.net>. But why is it a problem for mono ? (or is it something else entirely ?).
Of course I m an autoupdate or some other thing broke something, as it was working fine 3 days ago :(.
Does anyone have any idea as to how I could resurrect it ?
Below the content of the config file (it’s new, as I tried a complete reinstall to solve the problem)

EDIT: solved finally by fully removing both all package related to mono (apt get remove libmono*) followed by purge and autoremove. And then reinstall.
