The AppCenter is not updating. When I try to update on the AppCenter, I get:

Can anyone help me here? Thanks in advance.

It appears to me that the PPAs kxstudio-debian and nathandyer/vocal-daily are causing issues here. You might want to remove them.

To do so,

  1. Go to Applications
  2. Right click on Files and select New Window as Administrator.
  3. Then navigate to /etc/apt/sources.list.d.
  4. In this directory, delete anything that says kxstudio or nathandyer.
  5. Then try running an update; it should work.

Obviously, this means that you will no longer receive updates for KXStudio and Vocal.

For KXStudio, you can try to add the PPA from scratch later. For Vocal, unless you are a tester, you can just purchase it from AppCenter.

    I don't know what KXStudio is but I'm guessing it was installed with Mixxx. And I did purchase Vocal (I think it was my first purchase in the App Store) but I already had the previous package, before there was a store. Maybe the repositaries got broken. It's working, perfectly, after reinstalling both KXStudio and Vocal. You're the best, thank you for your help. – hainish Feb 13 '18 at 0:31
