VacuumRobots disableUpdates

Firmwareupdates and soundpackages require the command ccrypt to work properly. Any update must be decrypted by that command. By renaming it, you technically disable your vacuum's ability to update firmware/install soundpackages.

mv /usr/bin/ccrypt /usr/bin/ccrypt_

touch /usr/bin/ccrypt

chmod +x /usr/bin/ccrypt

Reverse (to install updates and soundpackages again)

Check that /usr/bin/ccrypt_ exists (you do not want to delete your actual copy of ccrypt)

rm /usr/bin/ccrypt

mv /usr/bin/ccrypt_ /usr/bin/ccrypt
