Any insight about fixing this?

I think something might be up with your system/dependencies.

Can you post the output of apt-cache policy gconf-service libgconf-2-4 ?

What happens if you run sudo apt -f install and sudo apt install libgconf-2-4? If these two commands offer a solution and you want to answer Y, triple check what packages are getting removed/installed so as to not remove needed packages by accident.

Latest Update: I switched the Download from from the MainServer to a mirror server, the apt install alarm-clock-applet works. But I have no idea why the Main sever is not working.

The output of the apt-cache policy gconf-service libgconf-2-4:

gconf-service:
  Installed: 3.2.6-7ubuntu2
  Candidate: 3.2.6-7ubuntu2
  Version table:

libgconf-2-4:

What happens if you run sudo apt -f install and sudo apt install libgconf-2-4?

I have failed to do like this, the execution result shows that the libgconf-2-4 and gconf-service are not available. Sorry, I did not keep the console output .

Switching server solved my problem, so feel free to close this issue.

The answer from AI:

The gconf-service and libgconf-2-4 packages are part of the GConf system, which has been deprecated and replaced by DConf. Many distributions, including newer versions of Ubuntu and its derivatives like Pop!_OS, have removed these packages from their repositories.
