Unable to contact snap store

Raghavender · March 20, 2020, 11:37am

Hi,
I am trying to install micork8s on my Linux machine using snap
But I am getting the error “Unable to contact snap store”

[raggadda@simphonyqa11ga ~]$ sudo snap install microk8s --classic
[sudo] password for raggadda:
error: unable to contact snap store

These are the logs from /var/log/messages

I am behind a proxy and I am able to hit the URL

curl https://api.snapcraft.io/api/v1/snaps/sections

Please help in fixing this problem.

Regards,

snapd reads /etc/environment so setting your systemwide proxy settings should get picked up by the snap install command.

Raghavender · March 20, 2020, 3:07pm

Hi @popey,

Thanks for your reply.
I tried keeping the proxy in /etc/environment, /etc/profile.d/http.sh and exported in shell too.
But nothing worked

how exactly do you define the proxy ?

it needs to be non capitalized like http_proxy= and https_proxy=

Raghavender · March 20, 2020, 4:57pm

Yes, it is non capitalized…
[root@simphonyqa11ga raggadda]# cat /etc/profile.d/http.sh
export http_proxy=http://www-proxy*****.com:80
export https_proxy=http://www-proxy*****.com:80

And I am able to curl the api.snapcraft.io URL as mentioned above.

ogra · March 20, 2020, 5:37pm

and you have it like this in /etc/environment ? (note that profile.d is only being parsed by login shells, not by services (i.e. snapd)…

$ grep Env /lib/systemd/system/snapd.service 
EnvironmentFile=-/etc/environment

Raghavender · March 23, 2020, 10:03am

Thanks, @ogra !!
The solution you suggested worked!

I replaced the “EnvironmentFile=/etc/environment” line in the file /lib/systemd/system/snapd.service and it fixed the issue.

[raggadda@simphonyqa11ga ~]$ grep Env /lib/systemd/system/snapd.service
EnvironmentFile=-/etc/environment
#EnvironmentFile=-/etc/sysconfig/snapd

[raggadda@simphonyqa11ga ~]$ cat /etc/sysconfig/snapd

What happens if you use a tool such as mtr to connect to api.snapcraft.io?

quersystem · September 28, 2020, 11:32am

root@lxd0x:/home/quersys# mtr api.snapcraft. io

popey · September 28, 2020, 11:35am

How about a simple curl…

quersystem · September 28, 2020, 11:38am

root@lxd0x:/home/quersys# curl -v api.snapcraft.io

Here is output

quersystem · September 28, 2020, 4:36pm

I did it! All is working!

UndefinedDecoder · January 20, 2021, 12:59am

What did you do to make it work?

mohammads_32 · February 17, 2021, 5:53am

Hello
I’ve installed ubuntu 20.10 on my RPi3-B (groovy-arm64) and have the same problem.
It’s fully upgraded-to-day. when I tried to refresh packages(like lxd), it returned:

ubuntu@ubuntu:~$ sudo snap refresh lxd
error: unable to contact snap store

The Internet connection is fine and other apps work perfectly.
snap can’t refresh, find and install any package!
I’m NOT behind any proxy.
snap known serial returns a valid device-key.
The ping and curl of the api.snapcraft.io is satisfying:

ubuntu@ubuntu:~$ ping api.snapcraft.io
