VIM4 firfox web browser not running

I’m install Ubuntu22.04 on eMMC

  • vim4-ubuntu-22.04-gnome-linux-5.4-fenix-1.0.10-220426-emmc-develop.raw.img.xz
    Firefox Web Browser is not running!!

Also…
I’m use command


khadas@Khadas: $ firefox
Command ‘/usr/bin/firefox’ requires the firefox snap to be installed.
Please install it with:

snap install firefox

khadas@Khadas: $ snap install firefox
error : cannot install “firefox” : Post
“https”//api.snapcraft.io/v2/snaps/refresh": dial tcp: lookup
api.snapcraft.io: no such host

@cinta

$ sudo apt update
$ sudo apt upgrade
$ sudo snap install firefox

Try with my steps. I had test it today.

Thanks!!!
