  • In general. the solution is to `--remove` via terminal (spartanidas answer) or uncheck via *Software Updater* (Ganesh Jadhav answer) the first PPA that is shown in the error message. And then rerun the update. – loved.by.Jesus Jun 07 '23 at 13:44

I fixed my problem by this:

1.First, restore the default focal repositories using these commands:

mkdir ~/solution cd ~/solution/

cat << EOF > ~/solution/sources.list 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 EOF

sudo rm /etc/apt/sources.list sudo cp ~/solution/sources.list /etc/apt/sources.list

2.Remove all the PPAs in your system:

sudo mv /etc/apt/sources.list.d/* ~/solution

3.Update the repositories:

sudo apt update
