My Python + wxPython application snap which references libgtk-3-0 builds and runs OK but I do have two missing libraries being reported.
On a previous linux system I was using, these came up as mere warnings and those libraries were ‘migrated into the snap to satisfy dependencies’ from the host filesystem:
Priming desktop-gtk3
This part is missing libraries that cannot be satisfied with any available stage-packages known to snapcraft:
- libgdk-x11-2.0.so.0
- libgtk-x11-2.0.so.0
These dependencies can be satisfied via additional parts or content sharing. Consider validating configured filesets if this dependency was built.
Should I be worried? Can anybody recommend what entries to my yaml are needed to fix this? My snap/snapcraft.yaml under Ubuntu 18.04 with snapcraft installed via snap looks like:

P.S. Any suggestions for a cleaner snapfile also appreciated, though, as I say, it works.
