The Team Kodi PPA has long been a staple for Ubuntu (and similar) users wishing to use more recent, and less adulterated, versions of Kodi. It is with sadness that the team has come to a decision…
Yes, that sandboxing works with graphical apps in addition to CLI apps and services, and there are several graphical applications that allow you to select connections for snapped apps, including KDE Discover.
The SELinux implementation is primarily there to ensure that SELinux’s enforcement doesn’t break snapped apps, but a side effect of the different model compared to AppArmor’s means that filesystem based sandboxing is only partial. And, of course, if the system has SELinux in permissive mode snapd won’t force it into enforcing mod. Specific vary from system to system, but it means that the filesystem isolation isn’t as good under SELinux as it is under AppArmor. Most of the sandboxing is done through cgroups, though, which is not dependent on whether one uses SELinux or AppArmor.
