Not long ago I had to re-install Ubuntu on my laptop and that went smoothly and I was back up and running in no time but I did not try to play a DVD on the system until recently and I was faced with
Could not read DVD. This may be because the DVD is encrypted and a DVD decryption library is not installed.
Thankfully a quick Google search turned up a post on the Ubuntu forums with my fix.
I am going to post it here for my own reference just in case I need to re-install Ubuntu again.
wget -c http://packages.medibuntu.org/pool/free/libd/libdvdcss/libdvdcss2_1.2.9-2medibuntu4_i386.deb
sudo dpkg -i libdvdcss2_1.2.9-2medibuntu4_i386.deb
wget -c http://packages.medibuntu.org/pool/free/libd/libdvdcss/libdvdcss2_1.2.9-2medibuntu4_amd64.deb
sudo dpkg -i libdvdcss2_1.2.9-2medibuntu4_amd64.deb
Hopefully this can help someone else. I am now happily watching DVD’s on my laptop again. Thanks to the help on the Ubuntu forums.
