Cannot access Snap Store or Ubuntu Software on Ubuntu 20.04 [duplicate]

Whenever I click on the Ubuntu Software icon, it does not open. The same is true if I use snap store links. When I try to open the store via the command line, I receive this error:

$ snap run snap-store
ERROR: not connected to the gnome-3-38-2004 content interface.

How can I resolve this?

Solution 1:

This is a very rare situation, but can usually be resolved by re-attaching snap-store to the content interface.

Here's how you can do it:

0. Open Terminal (if it's not already open)
1. Reattach the Snap:

   snap connect snap-store:gnome-3-28-2004 gnome-3-28-2004:gnome-3-28-2004 
   

   ^{Note: There is no output, so it will look like nothing has happened.}
2. Open the Snap Store normally (or via the Terminal)

Hope this helps 👍🏻
