You need to comment out those lines as it's not supported in xenial.

Usually in your Repositories and Other Software.

The 404s are accurate.
Look at the version numbers

Example xserver-common.
Current 16.04 is 1.18.4-0ubuntu0.2 in xenial-updates
You are trying to install 1.18.4-0ubuntu0.1, an older version, which has been replaced by 0.2

The simple solution is to update your package database. Make sure your mirror works, and that the database files really download (no errors).

sudo apt update

0.2 replaced 0.1, according to the changelog, on 01 November - have you had this problem for six weeks?

Once you are sure you have a good database update, then try upgrading again.
