✅ Step‑by‑Step: Manually Update the Snap Store in Ubuntu desktop 20.04.06

You can manually update the Snap Store on Ubuntu 20.04.6 by fully stopping its background processes and then running a targeted refresh. 

 The key is that the Snap Store often runs silently in the background, so you must terminate it before updating.

1. Stop all Snap Store processes

The Snap Store frequently runs in the background even when the window is closed. You must terminate it first.

Option A — Cleanest method

bash

snap-store --quit


If this works, proceed to the update step.
Option B — Force‑kill the process
If the above command reports that Snap Store is still running:

bash

pkill snap-store

or identify the exact process:
bash
or identify the exact process:
bash

ps aux | grep snap-store


sudo kill <process_id>

2. Refresh the Snap Store manually

Once all Snap Store processes are stopped,

bash

sudo snap refresh snap-store


This forces an immediate update of only the Snap Store snap.

3. (Optional) Update all snaps

If you want to update everything:

bash

sudo snap refresh
📌 Quick Troubleshooting Tips
If 

snap-store --quit 

does nothing, 
use

 pkill snap-store

If 
bash


snap refresh snap-store 


still complains about running apps, check for other snap processes:

 bash

ps -ef | grep snap

Then kill the listed PIDs.
After updating, the Snap Store may restart automatically.


ps aux | grep snap-store
sudo kill <process_id>
ps aux | grep snap-store
sudo kill <process_id>
ps aux | grep snap-store
sudo kill <process_id>c
ps aux | grep snap-store
sudo kill <process_id>ps aux | grep snap-store
sudo kill <process_id>
ps aux | grep snap-store
sudo kill <process_id>
