Chromium installation error in Lubuntu 20.04

I've installed Lubuntu 20.04 x64, and wanted to install chromium browser.

I used the command-

sudo apt-get install chromium-browser

but it displayed-

=> Installing the chromium snap 
==> Checking connectivity with the snap store
==> Installing the chromium snap
2020-04-24T16:08:43 INFO Waiting for restart...

It remained stuck at this message for almost an hour, until I've to finally kill the process.

Solution 1:

I had the same issue during an upgrade to Ubuntu 20.04. During the installation of the Chromium snap package, I would see this message:

INFO waiting for automatic snapd restart

And then the installation process was just doing nothing as that automatic restart never happened. So I unlocked progress in the installation process again by executing the expected restart manually:

sudo service snapd restart

Solution 2:

Snaps install through its service snapd and the client snap; that client failed for reasons unknown, so you must clear away the failed install. Run

sudo snap remove chromium-browser 

before trying again to reinstall. If reinstalling also fails, kill the snap client process again, and reset the Snap state using this script
