How can I download all current fedora24 updates for offline installation?

edit

Thanks for this info, but could you please tell me the next part, what command do i use to actually install ALL these updates on another computer once I have them downloaded?

I will copy the folder to a USB stick and bring it with me to my friends house. I assume once I have installed her the ISO of Fedora24 I can copy this folder into the same location on her machine, but what then?

To answer your question, my friend does not have proper internet access. She is in a remote location and relies on TERRIBLE french mobile phone tethering with a crazy low data allowance.

THANKS!

You can just point dnf at the *.rpm files. For example, if they're in /some/dir, then dnf install /some/dir/*.rpm

Awesome, thanks!

If i add the repos that the rpm's came from originally after, will they will still be able to update themselves when i do a dnf update? Or maybe they will just know where they came from and add the repos themselves?

Sorry, work was insanely busy for me for the last few days.

My guess would be that if you use the package manger to install them, then it will be "aware" of them and look for updates when you run dnf upgrade. If it doesn't initially recognize them when you try to update everything, then I would try running dnf install <package> for a specific package. It will either notice that the package is already there and up to date or reinstall it (hopefully the former).

what about if the machines don't have the same specs? I mean, there should be an easier (web based) way of download offline upgrades (not talking about systemd offline updates here). I'm a bit surprised...
