W: Problem unlinking the file lists - Clean (21: Is a directory) Error when running 'sudo apt-get update'

Question

I started seeing this error msg W: Problem unlinking the file lists - Clean (21: Is a directory)

whenever I tried to update using apt.

I have already tried sudo apt-get autoremove && sudo apt-get clean && sudo apt-get autoclean

but still the problem persists.

Need help pls. I'm running Ubuntu 16.04.1 64-bit

I don't use `apt-fast` and do not have this installed so that solution is not relevant — HuckleberryFinn, Aug 25 '16 at 02:17

You can delete all files in /var/lib/apt/lists/ and re-run apt-get update.
