Apply update automatically is not working

Hi,

I have an issue with the update manager in Mint 20.3 Cinnamon 5.2.7. It seems the option "Apply update automatically" is just not working. I have to manually apply the updates in the Update manager.

We can find the option in mintUpdate/Edit/Preferences/Automation. But even ticked, this is not working automatically, but working manually.
I have 3 sessions (for 3 users) on this computer, but each one is set like this.

I don't know is this issue is solved, but not for me :-(

Start at mintUpdate > Edit > Preferences > Automation and reproduce the issue with automatic updates enabled. Investigate why updates still require manual application on the reported Linux Mint 20.3 and Cinnamon 5.2.7 setup; done means enabled automation applies available updates without manual action.
