I had Ubuntu 13.10 installed on my laptop. After I upgraded windows, I tried to get grub back through Boot Repair
via these commands mentioned here:
sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update
sudo apt-get install -y boot-repair && boot-repair
But when I run first command I get this error:
Cannot add PPA: 'ppa:yannubuntu/boot-repair'.
Please check that the PPA name or format is correct.
what's the problem?
