So we're going to use the command line. First, open a Terminal with Ctrl + Alt + T, or search the Dash (click the Ubuntu logo) for Terminal. It looks like this:
Then type the following command into it and press enter:
sudo apt-get remove google-chrome-stable:i386
you can copy and paste by right clicking or using Ctrl + Shift + C in the terminal.
When you press enter, it will ask for your password. When you type it, nothing will show up (not even asterisks) but it is still letting you type it. Press enter when you have typed it, and the command will run, with an output similar to this:
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following packages will be REMOVED
google-chrome-stable
0 to upgrade, 0 to newly install, 1 to remove and 0 not to upgrade.
After this operation, 111 mB disk space will be freed.

When it finishes (the last line will look like username@computername:~$
), you can open the Software Centre and try to install it again. You can also close the terminal.
