Hello
Have about 100 pc connecting over slow GSM to the internet.
All have the same identical hardware and software installed on them.
apt-get update && apt-get upgrade takes 20-30 min on one PC.

i did 15 of them via GSM. And would like to speed this up.

directory
/var/lib/apt/lists holds the files downloaded with apt-get update, and directory
/var/cache/apt/archives/ contains all the files downloaded when doing apt-get upgrade

Would it work to copy contents of these two directories on a NON-updated/upgraded PC, and then do a
apt-get upgrade since the hardware and software on them is the same ??

Thanks

Maybe https://www.debian.org/doc/manuals/d...server_for_apt ?

I use NFS shared portage for all my gentoo boxes, I'm sure you could share all downloaded .deb packages over NFS.

Thanks for the input

We're using already apt-cacher, but connection to that server is trough GSM.


Idea was to use a Laptop with downloaded files from apt-get update and apt-get upgrade
i would scp files from two folders from already updated and upgraded online PC into the laptop

connect laptop with not upgraded pc with LAN cable
scp files from laptop to the pc
on the pc start apt-get upgrade

will this work ?

That seems like a sub-optimal choice.Probably just get the deb files and install on each with dpkg -i
