I can’t figure out why the keepassxc snap is no longer found or launchable from the gnome overlay.
It works on my xenial laptop, but not my artful one. I think it worked on my artful laptop at some point, but my memory might be wrong.
I found an answered question in askubuntu, but all of those packages are already installed on my system.
Aside, there is no longer a SnapTips wiki on the keepassxc repo. I was hoping to find advice there. 
It works fine for me, on 17.10
But I do have some variations from any standard system. I boot a non Ubuntu kernel with apparmor=0 and also,
$ snap info core

It shows up for me as well on a relatively stock 17.10 install. Do you
have a desktop file for it in /var/lib/snapd/desktop/applications/ ?
Yes. Odd. Actually, none of them are working. Maybe I changed some setting in gnome such that it doesn’t search all of the correct places.
It also works fine here on 17.10 wayland.
bionic here, it works without issues.
I can’t figure out how I’ve managed to break functionality for all of my desktop snaps. Any other suggestions for what to check?
