Feedback on the Lenovo Thinkpad T420

in the program "software sources"
check the box "software restricted by copyright or legal issues (multiverse)"
then you should be able to find it in the app-store

personally I use google-chrome as my web-browser
they package their own version of flash and are therefore more up-to-date with flash and upgrades than ubuntus flash.

http://www.google.com/chrome - do download it

I installed ubuntu image from http://www.ubuntu.com/certification/hardware/201102-7230:201102-7315.

I couldn't find "software sources" option to configure under "Ubuntu Software One".

Also, I tried to install chrome browser from http://www.google.com/chrome deb package and got the following error.
root@ubuntu:~/Downloads# dpkg --install google-chrome-stable_current_i386.deb

Hi,

Doing the following command solved all the installation/update problem.

sudo rm /var/lib/apt/lists/* -vf
sudo apt-get update

Thanks,
