Caching downloaded deb files with apt-cacher
It seems silly with multiple machines to download the same file multiple times. At some level it’s not THAT inconvenient. It really depends on your connection speed and the size of the files in question. For Ubuntu and other systems based on the .deb package format and apt-get there is a nice option for setting up proxy’ing to allow a single download of deb files for install on multiple machines. That option is called apt-cacher. There’s a good wrietup here on the setup of this cache -ing software.
