In terminal, can you please run

sudo apt update

and relay any 404 errors or other errors here?
Also run:

sudo apt --fix-broken install

and paste the output here?


I also had this error when I started using Zorin Os, sudo apt --fix-broken installfixes it.

Do you still have the error? If you still have it, restarting should fix it. You can run sudo apt autoremove to remove unused packages, BTW.

Probably just a dependency issue

Think that fixed it. The error message is gone. Thank you for helping. :grinning:


Can you also go ahead and run sudo apt full-upgrade

Glad to know everything is working.


yes I've done it


Out of my curiosity, may I ask what does Super Cow Powers mean?

I think it's just to warn the user to not destroy others computers

I don't get how the words "Super Cow Powers" can be used as a warning. :thinking:

I'm not too sure, you can ask @Aravisian.debian - What's the story behind Super Cow Powers? - Unix & Linux Stack Exchange, I found this link. :rofl:


You already answered it. :slight_smile:
Of which is also an homage to Gary Larson.


So, it's an easter egg. Did not know the man loved cows. :cow:


Haha, I also didn't know that he loved cows.

I tried getting the Easter egg and typed it wrong and accidentally found out that there is also one where he says "This aptitude does not have Super Cow Powers"


yes there is many Easter eggs.
