Can someone explain to me what is happening in this image? I'm relatively new to Ubuntu and I'm unsure how to fix this.

apt update error message

None of my repositories are updating anything. I've tried replacing all of the repositories with the stock ones I found below, but none of them seem to be able to connect, which I'm assuming is the error. Which is weird, because I just did an apt update last night but now I want to install Java and nothing is working.

deb http://archive.ubuntu.com/ubuntu/ focal main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu/ focal main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu/ focal-updates main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu/ focal-updates main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu/ focal-security main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu/ focal-security main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu/ focal-backports main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu/ focal-backports main restricted universe multiverse
deb http://archive.canonical.com/ubuntu focal partner
deb-src http://archive.canonical.com/ubuntu focal partner

I've tried deleting contents of sources.list and reverting with the software updater but that seems to crash for 20.04 when I click revert so I'm sol with that.

  • That PPA is severly outdated and perhaps not maintained. So better remove it. Last update was in 2018. Look here for details https://launchpad.net/~danielrichter2007/+archive/ubuntu/grub-customizer. You may download the .deb and install it with dpkg, but may not work. – Arijit Chatterjee Jul 04 '20 at 05:52
  • Sorry that stuff doesn't help guys. The default Ubuntu 20.04 repositories aren't working and I know the danielrichter one is old. I just need to get the default repo sources.ilist file working again as it's not. Does someone have a copy I can download and try or can send me their sources of the ones above aren't correct? – user25832 Jul 04 '20 at 07:57
  • Just to be clear. The sources above are my current sources.list file as well as the danielrichter source. I need someone to help me figure out why none of them are connecting. I have WiFi so whats up with those? They are for Ubuntu 20.04 and that's why they have the "focal" tag near the end. Thanks for the help – user25832 Jul 04 '20 at 08:02
  • Your output shows all of your sources updating properly...except for the PPA. Going forward, please copy/paste text instead of posting images of text. – user535733 Jul 04 '20 at 11:27

The message says that you have enabled a PPA that is no longer proving packages for your new version of Ubuntu 20.04. This can happen when you setup a PPA for Ubuntu 18.04, then upgrade your Ubuntu, and that PPA has no longer packages for the new version of Ubuntu (in this case, focal or Ubuntu 20.04).

Although the message says that the IP address is no found, the real issue is that the PPA has no support for Ubuntu 20.04.

When you remove a PPA, you need to take care of what happens with the orphan packages. Because those orphan packages will stay there and likely never get updated again.

In your specific case with grub-customizer, we can see from https://launchpad.net/grub-customizer/+packages that the package has actually been added as an official package to the newer versions of Ubuntu (starting from Ubuntu 19.04). That is, it is a case where a package, grub-customizer, has been promoted from a PPA to appear in Ubuntu for everyone to use.

Therefore, in your case, use the GUI tool to disable this specific PPA. Then, perform a package update and a package upgrade. Finally, verify the version of the grub-customizer package.

Here are the commands if you do not use the graphical interface,

$ sudo add-apt-repository --remove ppa:danielrichter2007/grub-customizer
$ sudo apt update
$ sudo apt upgrade
$ apt policy grub-customizer
grub-customizer:
  Installed: 5.1.0-2
  Candidate: 5.1.0-2
  Version table:
 *** 5.1.0-2 500
        500 http://archive.ubuntu.com/ubuntu focal/universe amd64 Packages
        100 /var/lib/dpkg/status
$

You should get the version 5.1.0-2 as I do above.

  • Yes but if I remove that I'm still going to have the error where the default Ubuntu 20.04 repositories don't work still would I not? That is what im pretty sure of and how would I fix it? Unless I'm wrong. I am a little confused. – user25832 Jul 04 '20 at 08:23
  • @user25832 after you remove the PPA and run sudo apt update, everything will be fine, as far as we can see from what you posted – Zanna Jul 04 '20 at 12:43
