Get rid of upgrade reminder

[Qqmike]

In 22.04, I got an upgrade invitation to 24.04, it's a round yellow icon in the system tray.
How do I get rid of that? (Don't wish to upgrade yet; don't wish to make a mistake.)

You probably need to edit /etc/update-manager/release-upgrades and edit the last line so it says "Prompt=never" then log out and back in.

That worked, after a re-boot.
I also removed the # from this line: # never - Never check for, or allow upgrading to, a new release.

Actually, after doing the edit, and closing and then opening Kubuntu, but before re-booting, that yellow icon was still in the tray.
However, it was "dead"! I clicked on it, and nothing happened (previously, it would ask for my PW).
After the re-boot, the icon in the tray was gone.

Thanks.
