Package 'cmake' has no installation candidate ubuntu 12.04

Solution 1:

I faced the same problem and after googling a bit, I become able to install cmake. I fixed my problem as follow:

sudo apt-get update -y
sudo apt-get update
sudo apt-get install cmake

Solution 2:

Try this:

sudo apt-get update -y
sudo apt-get update
sudo apt-get install cmake -y

I can install it only by adding '-y' in the third line
