Do you have another package handler like apt-get, aptitude, or synaptics running? If not, just manually delete it:

The only times I have seen an error like that is when I have forgotten to issue the "sudo" command before the command I want to run; mainly the "apt-get install <package>" one.

Thank you so much! You're right!

It's not that I forgot to add the "sudo" before, it's that I wasn't instructed to. Regardless, that did the trick. Now I no longer receive that could not open lock file blah blah message.
