I'm using Ubuntu 14. I'm trying to install GNU Radio and, when I try to configure, pthread library is missing. I then do:

sudo apt-get install pthread

I get this as return:

akula@akula:~/OpenBts/gnuradio-3.4.0$ cd ~

akula@akula:~$ sudo apt-get install pthread

Reading package lists... Done

E: Unable to locate package pthread

I already did all kinds of updates and everything else I found on the internet.

If anyone could help me, I would be grateful.
