Updating a snap

Asked by Moshe Caspi

1. What is done during pre-downloading a snap update (around 80MB are downloaded)?
2. Why does it look like the snap update is downloaded again during the update itself (around 80MB are downloaded)?

If you need to update your snaps.
Open a terminal[ctl+alt+t] :
sudo snap refresh

This will update all of your snaps.
Follow with :
sudo apt update && sudo apt upgrade

This will ensure your entire O.S. is up to date.

This is a question for the snap environment and has (at least in my opinion) nothing to do with Ubuntu. So I suggest that you ask at https://forum.snapcraft.io/c/snapd/5

Can you help with this problem?

Provide an answer of your own, or ask Moshe Caspi for more information if necessary.
