How do I fix this Apt error?

Question

When I try updating my system this error pops up.

Can anyone help?

E: Failed to fetch http://ppa.launchpad.net/pasgui/ppa/ubuntu/dists/xenial/main/binary-amd64/Packages 

Answer 1

This repository does not support Xenial.

If you need codeblocks, add the official PPA for the latest version (https://launchpad.net/~damien-moore/+archive/ubuntu/codeblocks-stable) or install it from the official repositories.

If you need builddeb, just install it from the official repositories (bzr-builddeb).

If you need DoUML, run:

git clone https://github.com/DoUML/douml.git
make
make install

Do be warned that DoUML is not completed and is still a work in progress.

If you need premake, the one in the official repositories should fit your needs (premake4).

If you need scite, just install the one from the official repositories.
