If there is no internet connection at the moment, will Synaptic and apt-get use the latest version in /var/cache/apt/archives/ ?apt-get uses a version in the cache if and only if it matches the requested version, regardless of the internet connectivity. 1) apt decides which version of a package it wants. 2) If that package version is present in the cache, it uses it. 3) Otherwise, it selects a mirror and downloads it from there.I may have some re-thinking to do. Due to bandwidth I avoid downloads whenever possible. Instead I purchase DVD sets. That's no real problem for the machine whose purpose resembles a typical user's. I have a couple of machines set aside for experimentation. They explicitly have no connectivity to the outside world. My mental image resembled using the cache contents as an local pseudo-repository. I may have to create a real one.I would take a look at apt-move
*THANK YOU* ! That does things I unsuccessfully attempted to do.
and apt-offline.
I had seen that before but had forgotten all about it ;{
Both look as though they could be of help.
Yes!
But don't forget that you can just stuff the cache, copying the files from one /var/cache/apt/archives to another. Just remember to set noclean wherever necessary.
I was thinking about that but wasn't sure it would work.
While you're reading man dpkg, realise that dpkg can (and sometimes must) install more than one package. --✄------ ACTIONS -i, --install package-file... Install the package. If --recursive or -R option is specified, package-file must refer to a directory instead. Installation consists of the following steps: 1. Extract the control files of the new package. --✄------ Back when dpkg was a more frequent topic of conversation here, people would get tripped up by mutual dependencies (A depends on B and vice versa) not realising that dpkg -i A B works. Perhaps a sprinkling of (s) suffixes would improve the man page. Cheers, David.
