How to Dismiss ‘Software Updates Installed’ Notification in Ubuntu

notificationsnapsnap-storeupdates

For days, Software has been nagging me to close snap-store so that it can update itself.

Now that's resolved and it has finally installed various updates, it shows a notification every time I boot up:

Software Updates Installed

Important OS updates have been installed

[ Review ] [ Cancel ] [ OK ]

No matter whether I click Review, Cancel or OK, it still displays this notification next time I reboot.

How can I dismiss it permanently?

I found an old discussion about the problem on the Debian forums (https://forums.debian.net/viewtopic.php?t=121809)

The solution is to delete the logfile at /var/lib/PackageKit/offline-update-competed. This solved the problem for me and is less invasive than removing "gnome-software".
