I filed a bug on launchpad that ended up being a duplicate of https://bugs.launchpad.net/snappy/+bug/1591148 which affects Mate for Pi but it isn’t referenced anywhere. Being a barely technical user I’m not positive how launchpad works and if things like this have a way to trickle down to anyone affected.
I haven’t been able to get a snap to install yet and this seems like a fairly significant problem that everyone would have so I’m fairly certain I don’t have to worry too much about it personally, however the question is more general about how bugs are posted, followed, or shared.
