I am also running into the same problem. Snapcraft is awesome, I love what it does, but the timing of this is unfortunate for me. Any way to get past this and get snaps building again? I am building on a local machine, and network is connected and fully operational, but seems like there there is a problem with communication. What can I do to get past this? I need to get this out the door and into production soon.
error: cannot refresh “core18”: unexpectedly empty response from the server (try again later)
Error while refreshing snap ‘core18’ to channel ‘latest/stable’
Run the same command again with --debug to shell into the environment if you wish to introspect this failure.
Looks like there is a service outage for snap refresh:
“Intermittent access issue in few services for 1 Mins 42 Secs”
But still cant seem to pull.
After some time and multiple attempts, it eventually passed. Took a while. If you see this issue it may be an external issue. Check the status page and give it some time and try again and again until it works.
