How can you have multiple releases in your Ubuntu program?

Asked by michael

On question #249590 I made a comment. I have now closed it, because it is a question, for my information.

What causes this? Copy and Pasted from the question #249590. The person who asked this question stated he was running Ubuntu 10.04.

Did you upgrade through the releases sequentially?

When I look at https://answers.launchpad.net/ubuntu/+question/249590 I conclude the following:

The configuration file /etc/apt/sources.list contains the following lines (among others)

22 deb http://archive.ubuntu.com/ubuntu lucid multiverse
60 deb http://cz.archive.ubuntu.com/ubuntu trusty main universe
65 deb http://cz.archive.ubuntu.com/ubuntu utopic main
66 deb http://cz.archive.ubuntu.com/ubuntu precise main

This is an absurd combination of the repositories for different Ubuntu releases in that file and I am not surprised to see problems during a package upgrade attempt (broken dependencies etc.).

When looking at the comments above each of these lines in the sources.list file, it seems to me that these entries have been added manually, and not by some fault in a release upgrade attempt with the standard tools.
