Connection to the snap store failed

Hi Support,

We have a Ubuntu 18.04 server running on cloud. Now, We are trying to upgrade the server to Ubuntu release 20.04 using

sudo apt-get update

sudo apt-get upgrade -y

sudo apt-get dist-upgrade -y

sudo apt-get autoremove

sudo reboot


sudo do-release-upgrade.

While running the mentioned commands, popping up an error saying “CONNECTION TO THE SNAP STORE FAILED”.

NOTE: JFI, Tried as root user too. Ports 443 and 80 opened

So please help us resolve this error and upgrade the server ASAP. ERROR Attached.

This sounds like a transient error from the store - is this still occurring?

Thanks for your message,

The issue got cleared. Snap System Proxy settings was not configured.
