sudo apt-get update fails

Fix for:

Could not get lock /var/lib/apt/lists/lock - open (11 Resource temporarily unavailable)

ps -e | grep apt : shows if any apt processes are running

sudo kill : kill the apt process if running.

Example:
-ubuntu:~$ ps -e | grep apt
5502 ? 00:00:00 apt
5548 ? 00:00:14 apt-get
ubuntu:~$ sudo kill 5502
ubuntu:~$ sudo kill 5548
ubuntu:~$ sudo apt-get update

After a long gap, you open you vim for coding and forget what argument in the source and what is the destination for strcpy or what params to pass for doing some geeky ioctl calls. So ask your good old man, by "man strcpy" or "man ioctl" and your man says "No manual entry for whatver you ask".

Type this one your Ubuntu terminal:
sudo apt-get install manpages-posix manpages-posix-dev gcc-4.4-doc c-cpp-reference
