Hey there,

I did some research on the output you provided and it looks like you may need to update your repository targets. While you are running 19.10 (Eoan Ermine), your attempted update was looking for repositories for 19.04 (Disco), which is now an unsupported version of Ubuntu.

Users on a Stack Overflow post about issues performing apt-update have had similar issues regarding your current version of Ubuntu. It looks like making a change to the sources.list file with the below commands solved the problem:

sudo sed -i -e 's|disco|eoan|g' /etc/apt/sources.list
sudo apt update

If you are interested in taking a closer look at package-management you can take a look at our documentation on apt for Ubuntu. The guide goes into detail about apt commands as well as provides even more references.

I hope that this helps and if you have any other questions please reach out to us.

Regards,
