I have the stable version of Google Chrome on my box. And each time I'm trying to install beta or/and unstable versions then I run into the same problem:

The following packages will be REMOVED

  google-chrome-stable

The following NEW packages will be installed

  google-chrome-beta

0 upgraded, 1 newly installed, 1 to remove and 0 not upgraded.

Need to get 34.5 MB of archives.

After this operation, 3,109 kB of additional disk space will be used.

Do you want to continue [Y/n]? 

I need to remove the first version before installing another.

I know I can't install existing packages side by side. It doesn't need to be done via packaging system! I don't care how it's done. It equally can be hand crafted bash script or anything else. Main goal is to have them next to each other on my Ubuntu. There needs to be a way..

So summarizing my question: How can I install all Google Chrome versions next to each other?
