Sample dnf.conf and repos

edit

Here is an example of my almost-default dnf.conf file.

[main]
gpgcheck=1
installonly_limit=6
clean_requirements_on_remove=True
defaultyes=1

To reinstall the repository files in /etc/yum.repos.d, using root permissions or logged in as root, for Fedora 26 you should be able to do the following:

wget https://download-ib01.fedoraproject.org/pub/fedora/linux//releases/26/Everything/x86_64/os/Packages/f/fedora-release-26-1.noarch.rpm

rpm --force -Uvh fedora-release-26-1.noarch.rpm

You can find the rpm from here and select the one matching your fedora version. This one is for f26

Once downloaded you can install it using (as root)

rpm -v --reinstall fedora-repos-26-1.noarch.rpm

Or to unpack the rpm without installing

rpm2cpio fedora-repos-26-1.noarch.rpm | cpio -idmvu

You can also clone the git repository

git clone https://pagure.io/fedora-repos.git
