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
and
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.
