[ubuntu] About upgrade 20.04 to 22.04

Hi all,

During upgrade Ubuntu 20.04 desktop to 22.04 desktop following warning popup;


upgrade to Ubuntu 22.04 your system unable reach snap store

Please advise what is this problem and how to fix this problem?

After upgrade finished on Terminal;
$ sudo snap install firefox


Setup snap "firefox" (2067) security profiles |
firefox 106.0.5-1 from Mozilla✓ installed

I can install and start Firefox without problem.

I made this upgrade-test on a cloned Ubuntu 20.04 VM of VirtualBox. I can clone another Ubuntu 20.04 VM to test again.

Please advise. Thanks in advance.
