I just upgraded the packages on my 18.04 machine and after reboot I see a new symbol in my top right that looks like a shield with a red "denied" symbol on it.
After further investigation this turns out to be the icon for the "livepatch" feature. It is notifying me that "livepatch" is off, and urges me to register to enable it.
I have zero interest in livepatch. I never opted to install this feature. I guess if I don't do something this shield will stay annoying and in-my-face 24/7-365?
Anyway I need help to remove it permanently like it never existed in the first place. Like completely deleted from my OS. Any help is much appreciated.
EDIT-1: Clarification in case you think I want to simply hide the notification. I actually want to COMPLETELY OBLITERATE IT and leave behind only unlinked inodes.
EDIT-2: I don't have livepatch installed. In fact look at this screenshot:
sudo snap remove canonical-livepatch
/usr/lib/systemd/user/update-notifier-livepatch.service
. It seems that you must have/usr/lib/update-notifier/livepatch-notification
? Perhapssudo ubuntu-advantage disable-livepatch -r
is what you seek (from that apps man page).
