export package

edit

Hi:

It's not possible to do that, once the .rpm is installed it's no longer kept on the machine (by default, could be possible to keep all the packages, but that could require some extra work). But, what you could do is to list all the installed packages

sudo dnf list installed | cut -d" " -f1 | sort -u > my_packages.txt

and then use that list as input for dnf to install the same packages in the new box

cat my_packages.txt | while read package; do sudo dnf -y install $package; done

(the above line is not nice, and it's possible to improve its performance, but should do the trick quick and dirty ;) )

Make sure that you have installed/enabled the same repos in both machines (RPMFusion et al)

Regards
