Upgrade available notification persistant notification

Hi Team,

KDE neon with plasmashell 6.8.1.

After each reboot Upgrade available notification appears, It fails with

localuser:root being added to access control list

Checking for a new neon release

There is no development version of an LTS available.

To upgrade to the latest non-LTS development release

set Prompt=normal in /etc/update-manager/release-upgrades.

Is it bug or any other issue ?

Same issue for me. I just want to disable the check/message, I never want to update.
