Ubuntu: fix unable to update Snap Store

In Ubuntu 20.04 I faced an issue with the Snap Store after a fresh install.Every time I tried to update the Snap Store ("Ubuntu Software") a pop-up message from the top of the screen notified me an error:

Unable to update "Snap Store": (null): cannot refresh "snap-store": snap "snap-store" has running apps (ubuntu-software)

After researching and testing a few solutions that didn't work for me, I decided to use brute force.

Step 1: Close the Snap Store

To update the Snap Store, it must be closed.

  • Usually I have to kill the running process. Launch the terminal and run:
    killall snap-store

Step 2: Now update

Now copy and paste in the terminal:

  • sudo snap refresh snap-store


Updating Snap Store can take time, especially after a fresh install like my case and depending on the speed of your internet connection. You be patient.

Successfully tested on Ubuntu 20.04 - 22.04 LTS.
