I have a linux mint install that will be placed on a private network without internet access. Is it possible to download an Apt mirror for Mint and place in on a server in the private network so that I can install from that server? If so, how do I do that?
the simplest ways is to use apt-cacher for debian-based systems, if the number of servers is not that large.
apt-mirror will create full mirror, if apt-cacher is not sufficient.
