The Issue
We want to disable snapd service on system startup/prevent snapd services startup automatically on system boot on Ubuntu or remove Snap completely

To uninstall snap (If necessary), we need to make sure snap is not used at all.

If we want to uninstall/remove snap just follow the below steps

2.1 List all snaps

snap list

2.2 If there is any installed snap pckage e.g. bashtop, remove all of them one by one

sudo snap remove bashtop

sudo rm -rf /snap
sudo rm -rf /var/snap
sudo rm -rf /var/lib/snapd
