Raspberry Pi 2: edge core snap seems broken

I’m currently running the edge rpi2 image (since that’s the only place GPIO works), and I’m trying to connect an interface. It won’t let me, saying core has “changes in progress”:

Something seems wrong with the configure hook, is that right? Also, preventing me from connecting interfaces while core is refreshing seems silly, no?

Huh. I aborted that change, but I can’t seem to be able to refresh to stable either:

I ended up rebooting after a few minutes and then the update (to stable) went the rest of the way through. How odd.

There was a bug with core in edge where you had to “snap abort” the “Doing” bit (learned about it on IRC yesterday) … i assume your reboot caused the same as a “snap abort” here …

The newer core snap should have this behaviour fixed now i was told.
