I don't seem to find any information where to report issues with snaps, i.e. applications which are installed through snap install instead of the system package manager apt-get.
Since most bug reports on launchpad.net are simply ignored, but still make sense to be filed, I'd like to make sure that I'm not doing something even more hopeless when filing bugs with ubuntu-bug or manually on launchpad.net.
The fact that apport says that a package isn't installed shouldn't say too much because it usually takes years until this tool is upgraded to reflect changes in the requirements.
