Unable to locate package libopenmpi-dev on 12.04

Question

While trying to install open mpi on my Ubuntu 12.04, I am getting error unable to locate package libopenmpi-dev. What to do?

$ sudo apt-get install libopenmpi-dev openmpi-bin openmpi-doc
unable to locate package libopenmpi-dev
unable to locate package openmpi-bin
unable to locate package openmpi-doc

Solution

Try to run apt-get update before you install the openmpi package.

Also you can use the following command to search all openmpi related package, for example:

apt-cache search openmpi

If it still doesn't work, try to use a different mirror, below is GUI and easier:

sudo software-properties-gtk

Update:

@Govind

The package is definitely in the official repository (12.04): http://packages.ubuntu.com/precise/libopenmpi-dev

As mentioned earlier, please run apt-get update and then apt-cache search for the libopenmpi packages.

If it still doesn't help. Try to change your mirror. Or paste the content of your /etc/apt/sources.list

Thanks Jokerdino for your suggestion but apt-cache search openmpi not giving any result .Is that possible that libopenmpi is not available for Ubuntu 12.04 ?because it was working fine on my Ubuntu 10.10.

just apt-get returned me error Could not open lock file /var/lib/dpkg/lock-frontend - open (13: Permission denied) as I was not in root, sudo solved that.
