I don't know why instead of EOL was closed as Duplicated, but in both cases it makes you upgrade your system with the question that was marked as duplicated.
To the people insisting I upgrade Ubuntu: my question is how to run something later than Chromium 25 on Ubuntu 10.04. "Impossible because xxx" is an answer. "Upgrade Ubuntu" is not.
Why Upgrade Ubuntu is not? At the end of the day you want to run latest Chromium and we are telling you what you need to reach that goal. If we start to detail all dependencies that you need to run the latest on the obsolete, what problems you might find, a long etc. it will not end. So we told you in comments Ubuntu is too old, hence you couldn't expect to run the latest software on it and direct you to how you can solve the "old" problem and run Chromium.
We are telling you exactly what is the problem (without boring anyone with technical details) and how to solve it in a single step. Why insist in trying to get an explanation of something that might not be of your interest (that I presume is running Chromium whatever it takes) taking us time.
The community is the one that decides the best method to help you, and we considered that we are helping you to do what you wanted to do. Unless you edit your question and explain what exactly is your goal, as the question is that is the only path to take.
