Catalina 10.15.3 update keeps on popping up and won't stop no matter how many times I click on "Install"

This is what worked for me:

Download macOS Catalina 10.15.3 Combo Update

https://support.apple.com/kb/DL2030?viewlocale=en_US&locale=en_US

I did NOT load it in 'safe' mode

and the 'update available' message went away...

Get it here & try installing it in Safe Mode....

https://support.apple.com/kb/DL2030?viewlocale=en_US&locale=en_US

Safe Boot from the HD, (holding Shift key down at startup), does the problem occur in Safe Mode?

That did not work. When started in Safe Boot the red circle with a 1 is still there but said all up to date with prior version. When restarted normally, the update shows up again but does not install. Message says requires restart and when that happens it pops up again.

Any luck?

macOS catalina 10. 15. 3 update stuck in 'install' loop. 'won't install but keeps notifying to install

Thanks. :)

Same thing is happening to my MacBook Pro ....
