Getting Ubuntu Restricted Extras to work

Hello, I must warn you that I do have some limited computer experience, but I am new to Ubuntu and Linux. I have a System 76 Pangolin Performance Laptop running Ubuntu (Ibex, I think). I cannot play DVD's in the reader. I visited the the system 76 help forum and tried to get the Ubuntu Restricted Extras to install, but I get the message that there is a conflicting program and that it cannot install until it is resolved. Has anyone had any experience with this? Please help and be gentle. Thank you, Sabhr

Try doing the install through the terminal:

sudo apt-get install ubuntu-restricted-extras

Then, post the output back to the forums so we can see what is keeping you from installing the package.
