Unable to install any application from Snap Store

snapd
1

m fairly new to linux Ubuntu and i was trying to install a few apps from the snap store. Im using Ubuntu since a month and have played around a bit and reinstalled Ubuntu again. On my new installation the ubuntu store is not working at all with my broadband connection through a wifi adapter. However if i use my Phone’s Sim Card data then the store works fine and im even able to do snap refresh without errors. I understand that there is some problem with the network itself but i did not face any issue with the same network on the same adapter on the previous installation of Ubuntu.

Currently if i do snap refresh this is what i get: error: cannot refresh: cannot query the store for updates: got unexpected HTTP status code 408 via POST to “https://api.snapcraft.io/v2/snaps/refresh ”

Getting same error in the store as well. Although i was able to install a few apps initially right after the installation. My network speed on 5G: 131.9 Megabits per second

Im clueless! Thanks in advance.

Exactly the same here.

I need a solution. I’m only use Snaps because I have to.

Watching Wireshark it’s pretty clear that the servers are being contacted periodically, but nothing is ever achieved (and nothing in the syslog).

What is the process of this “Device initialisation”? Does it need the server to do something?

As the request is sent over HTTPS I can’t see what data is actually being sent/received.

Is it trying to authenticate? Should it be trying? Is my machine given a GUID and it authenticates with that? What is it doing?

I also have this exact error, and effectively can’t refresh snaps at all, it is 100% repeatable and it depends on what snaps are installed.

It refreshes without a problem if I have only one small snap installed, but immediately stops working for example if I install firefox.

I’m on Kubuntu 22.04.

Here is a relevant log fragment of snapd, with DEBUG turned on:

Hi Kenway/RefreshingSnapper/tiangou,

Are you still experiencing the reported issue?

9

Variably, but a lot less often.

10

(apart from kenway’s setup) Are there any obvious complexities with your network setup (firewalls, proxies, enterprise setup etc)?

11

Nothing unusual.

Ethernet connection to the router which started as a DSL connection, and then I moved to a cable modem. Inbound firewall enabled on the router(s), no firewall on the machine. No outbound blocks of any kind.

It wouldn’t work for months on end. Then one day it did. The server always responds to ping.

Sorry for the bump but heres the solution i posted
