This is causing endless problems as more and more applications are
distributed as appimages or in some other way that is affected by this.
If there is a requirement for Ubuntu developers to implement a separate
config entry for every one of these applications, there is no hope for
users not to get frustrated again and again. I had probably a dozen
occasions in the last couple of months where this problem kept me from
running an app as intended.

Please note that every user facing this problem will go on the internet, search for a solution and come across two things:
* app developers putting the blame on Ubuntu 
* helpful users providing crypting scripts which completely disable any security protection in order to make the app run. 

There should be a simple and standard way for automatically providing
the proper and most secure configuration for all cases where the user
basically wants to trust the downloaded appimage. If this is not
possible, then there is a real serious design flaw in the way of how
apparmor works because it either prevents peopel from running software
completely or forces them to work around the limitiation in a way that
is the most unsafe one imaginable.

I urge developers to do a google search and browse through hundreds if
not thousands of articles where people report problems and others
provide ad-hoc arbitrary workarounds. And those are just the tip of a
much bigger iceberg because, as usual, most users do not bother posting
anything and simply give up.
