Hello guys!
I was running out of space on my Ubuntu box so I decide to clear apt-cache packages.
After this I cannot install anything due an error: “Archive directory /var/cache/apt/archives/partial is missing"
The fix is quite simple and works fine on my Ubuntu 10.04 Lucid.

• Close Synaptic or any other apt-based manager
• Open a terminal and run the following commands (please be sure to us sudo!):
  sudo mkdir -p /var/cache/apt/archives/partial
sudo touch /var/cache/apt/archives/lock
sudo chmod 640 /var/cache/apt/archives/lock

Now you can update your Synaptic or run sudo apt-get update

Next time to clean the cache directory I will use the right command sudo apt-get clean

That’s all! 😉
