    Snapd Management Scripts

This gist contains some simple scripts that enable control over Snap's automatic updates.
Scripts


disable-snap.sh - Disables the snap service and blocks updates.
enable-snap.sh - Enables the snap service and allows updates and managing the snap package database.
update-snap.sh - Temporarily enables snap and updates all packages. Disables snap when finished.
install.sh - Installs all scripts as global commands.

Setup (blocking automatic Snap updates)


Run chmod +x install.sh && ./install.sh to install the scripts to your computer.
Run disable-snap to disable Snap and block updates.
That's it, snap updates are now blocked!

To manually update snaps, run update-snap.
To install new snaps or remove existing snaps, run enable-snap before executing your commands. When done, run disable-snap to block updates again.
Disclaimer / Caveat

The scripts in this gist are simple and implement a fairly crude and heavy-handed approach to disabling snap.
As a result, it is impossible to run most snap commands while the snap service is disabled.
For example, you cannot install a new snap package or even list installed packages while snapd is disabled.
In some cases, applications that attempt to communicate with snapd may hang or crash rather than exit gracefully.
