I’d still quite like a global switch on the user side, I’m on less than 1mbps Internet (yes - megabits, not megabytes; UK Government failed to fulfil their pledge to have minimum 2mbps everywhere by Dec 2016) and automatic updates take up bandwidth and make the Internet unusable for my house, so I have to kill the snapd process… I can disable Apt updates from Software & Updates, graphically, but I can’t disable snap updates at all, graphically or via the command-line…
This is probably a separate issue sorry, has got a thread here…
