I installed Ubuntu 18.04 yesterday. Today I tried to install micro editor through snap, but it doesn't work. Any command like this sudo snap install hello-world freezes for a minute and I receive

error: unable to contact snap store

Is there some problem with the snap store or is it because I couldn't connect to it from my network? How could I check that?

  • Just got this myself. I was able to ping Google and login to snap, but find and install return this error. – Eric Fossum May 9 '18 at 13:52
  • Looks like they have some troubles with servers. Their website is also very unstable in this moment. – BlueManCZ May 9 '18 at 13:53
  • Looks like it's working now (I was also getting the same erorr) - would recommend trying again! – lightningmanic May 9 '18 at 14:12

Seems there might be a problem with the snap store this morning. Occasionally I get a successful return.

  • I keep getting error: unable to contact snap store from months, from any Linux virtual machine I create. I guess it's not simply a snap store problem. – kiamlaluno Jan 26 '20 at 8:34

You might get that error when you are trying to install something through snap behind proxy.

Configure the proxy with these commands:

# sudo snap set system proxy.http="http://<proxy_addr>:<proxy_port>"
# sudo snap set system proxy.https="http://<proxy_addr>:<proxy_port>"

Snap store might simply be down. Too bad this stalls. Refreshing snapd is supposed to fix this (?) according to a solution I saw, but it does not work because the web API is down. I don't know if the API spec changed, but it is currently the case that the host is not resolved. You have to wait until the store is back up. PS: There was probably a server change which takes time to propagate in my case.

$ sudo snap refresh snapd

error: cannot refresh "snapd": cannot refresh snap-declaration for "chromium":
       dial tcp: lookup api.snapcraft.io on no such host
$ host api.snapcraft.io
;; connection timed out; no servers could be reached

I got the same error just now. A solution that worked for me was:

in terminal:

$ killall snap-store

Then the snap connection was back
