I'm on Ubuntu 16.04LTS, and I'm trying to install MonoDevelop through the Flatpak package.
I am almost done, only thing missing is the runtime. When I run the following command I get an error:
flatpak run com.xamarin.MonoDevelop
error: runtime/org.freedesktop.Platform/x86_64/1.4 not installed
Then I try to install it:
flatpak install gnome org.freedesktop.Platform//1.4

error: While pulling runtime/org.freedesktop.Platform/x86_64/1.4 from remote gnome:
Error resolving 'sdk.gnome.org': Temporary failure in name resolution
Sometimes it doesn't show "Receiving delta parts", it goes straight to the error.
Maybe the repository for this runtime is broken, or the server! Can someone point me in the right direction?
The issue was in the file /etc/resolv.conf which had the nameserver 127.0.0.1, I changed it to 8.8.8.8 so I could carry on with the runtime installation.
You can also try to run: sudo service network-manager restart
I think that will reset the 127.0.0.1 to 127.0.1.1, otherwise change it manually as I said to 8.8.8.8 and it'll work.
