When attempting to install Google Chrome on Oneiric, you may encounter an error such as the following in the Ubuntu Software Centre:
The file “google-chrome-stable_current_i386.deb” could not be opened.
Though depending on which installer you’re using, the filename may be different of course. To work around this you can install it manually by running the following commands:
sudo apt-get install libxss1 libcurl3
sudo dpkg -i google-chrome-stable_current_i386.deb
Again, adjust the filename depending on the installer you have.
