+==== '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:
+   Apt::Cache-Limit 67108864;

+Delete the file '**/var/cache/apt/pkgcache.bin**' and re-run '**apt-get update**'.

+   sudo dpkg --set-selections < package_list.txt
+   sudo apt-get -y update
+   sudo apt-get dselect-upgrade
