Dynamic MMap error while updating

Well, I was doing some updating while testing some unstable Debian packages, and I figure some other people out there might run into this too if they're doing big updates. So here it goes.

This procedure was developed using the Xubuntu 7.04 (Feisty Fawn) Alternate Install CD running XFCE. As always, be careful when editing your system configuration files, or following any procedures from any site, as you can do harm to your system if a mistake is made. Always make backups of the configuration files that you change, or you might just find yourself with a broken system that's a pain to fix.

I was at the Terminal and typed sudo apt-get install PROGRAM, only to find myself with the error stating:

Reading package lists... Error!
E: Dynamic MMap ran out of room
E: Error occurred while processing shogun-python-modular (NewVersion1)
E: Problem with MergeList
E: The package lists or status file could not be parsed or opened.

The fix isn't too bad. You will edit one of two files, use whichever you have. You will edit either /etc/apt/apt.conf or /etc/apt/apt.conf.d/70debconf using sudo mousepad (or your text editor of choice) at the terminal. Backup the file now, just in case something goes wrong. Now, to the end of that file add the line APT::Cache-Limit "#"; where # is any value of blocks as long as it is less than the total amount available on the disk. This can be checked using the df command at the terminal. Save the edited file after double checking for any typos. Now when I run sudo apt-get install PROGRAM I get through the install without a hitch.
