This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

" another process using it?"

If Synaptic Package Manager or other are running try closing them, and then run the command again.

Exit software centre or any other software install programs before running it, rebooting may also help.

Or try zurdo's answer from here:

This should be used as last resource. If you use this carelessly you can end with a broken system. Please evaluate other answers first before trying this.

You can delete the lock file with the following command:

sudo rm /var/lib/apt/lists/lock

You may also need to delete the lock file in the cache directory

sudo rm /var/cache/apt/archives/lock

After that, try opening Synaptic again.
