Package 'cmake' has no installation candidate ubuntu 12.04

Question

When I run

sudo apt-get install cmake

I get the following response:

Package cmake is not available, but is referred to by another package.
This may mean the package is missing, has been obsoleted, or is only available from another source

E: Package 'cmake' has no installation candidate

How do I install cmake?

Answer 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

Answer 2

Have you enable the universe repository? Which version of Ubuntu?

Try this: https://launchpad.net/~kalakris/+archive/cmake.

It's a PPA with the newest cmake. I confirm to you that cmake exists and can be installed with:

apt-get install cmake

Answer 3

I used command: "sudo apt-get install cmake-gui" and got error message as below

Package cmake-gui is a virtual package provided by: cmake3-qt-gui 3.5.1-1ubuntu3~14.04.1 cmake-qt-gui 2.8.12.2-0ubuntu3 You should explicitly select one to install.

I then changed my command to "sudo apt-get install cmake-qt-qui" and it works.
