+==== 'apt-get' (Debian) says "E: Dynamic MMap ran out of room" and bails out ====
+Create a file **/etc/apt/apt.conf** and put something like:

+Delete the file '**/var/cache/apt/pkgcache.bin**' and re-run '**apt-get update**'.
+==== Create a backup list of packages and resinstall ====

+Save the text file on a thumb drive, format the drive, reinstall Ubuntu/Debian, then to a
+   sudo dpkg --set-selections < package_list.txt
+   sudo apt-get -y update
