I installed MonoDevelop 6 via FlatPak (http://www.monodevelop.com/download/linux/). Now I'm trying to attach to a running process to be able to debug it. But all I can see in MonoDevelop under Run --> Attach to Process are four processes, I guess from inside the FlatPak sandbox.
How can I attach to a process with MonoDevelop running inside FlatPak?
