I see the following repositories when I do a repolist:1) google-chrome2) rpmfusion-nonfree 3) rpmfusion-nonfree-updates-testingBut commands like yum install vlc and others line yum install gstream-plugins-ugly do not not work.I tried installing the free rpmfusion repos[root@dhcp223-30 yum.repos.d]# sudo rpm -ivh http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpmRetrieving http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpmwarning: /var/tmp/rpm-tmp.M25qoM: Header V4 RSA/SHA1 Signature, key ID 97f4d1c1: NOKEYPreparing...                          ################################# [100%]package rpmfusion-free-release-23-0.1.noarch (which is newer than rpmfusion-free-release-22-1.noarch) is already installedfile /etc/pki/rpm-gpg/RPM-GPG-KEY-rpmfusion-free-fedora from install of rpmfusion-free-release-22-1.noarch conflicts with file from package rpmfusion-free-release-23-0.1.noarchfile /etc/pki/rpm-gpg/RPM-GPG-KEY-rpmfusion-free-fedora-latest from install of rpmfusion-free-release-22-1.noarch conflicts with file from package rpmfusion-free-release-23-0.1.noarchfile /etc/pki/rpm-gpg/RPM-GPG-KEY-rpmfusion-free-fedora-rawhide from install of rpmfusion-free-release-22-1.noarch conflicts with file from package rpmfusion-free-release-23-0.1.noarchfile /etc/yum.repos.d/rpmfusion-free-updates-testing.repo from install of rpmfusion-free-release-22-1.noarch conflicts with file from package rpmfusion-free-release-23-0.1.noarchfile /etc/yum.repos.d/rpmfusion-free-updates.repo from install of rpmfusion-free-release-22-1.noarch conflicts with file from package rpmfusion-free-release-23-0.1.noarchand then enabling it[root@dhcp223-30 yum.repos.d]# sudo dnf config-manager --enablerepo=rpmfusion-free-release-stableError: Unknown repo: 'rpmfusion-free-release-stable'Please use the link to find the output of dnf repolist allhttp://pastebin.com/AqgCdCSUTIA

Reworked answer based on new info; and a couple of quick edits subsequently - What Happened to your Fedora Repos?Did you edit out the fedora repos from your dnf repolist outputs?Because you don't appear to have them...And maybe lets confirm you are running fedora 23 :) cat /etc/redhat-releaseAssuming you are truly missing them, do the following, otherwise jump ahead to the 'At least we have fedora repos' sectiondnf install ftp://195.220.108.108/linux/fedora/linux/releases/23/Everything/x86_64/os/Packages/f/fedora-repos-23-1.noarch.rpm# make sure they are enableddnf config-manager --set-enabled fedora updates updates-testing# cleandnf clean all# Optional, potentially large update, but I highly recommend it.dnf updateIf you got a large update, particularly if the kernel, systemd, dnf / yum / rpm were updated then reboot before contuining:At Least We Have Fedora Repos NowThe following commands will remove all of the rpmfusion repos and reinstall the latest version. Barring any errors on route, we should then be able to enable them appropriately. If you get failures similar to those you received before:file /etc/pki/rpm-gpg/RPM-GPG-KEY-rpmfusion-free-fedora from install of rpmfusion-free-release-22-1.noarch conflicts with file from package rpmfusion-free-release-23-0.1.noarchat any point, stop, and move right to the section on removing GPG keys from RPM, located at the bottom of this post.  Hopefully you don't have to do that it. It's not pleasant. One caveat - I don't have any more fedora 23 machines; just F24, so I tested this code on one of those. Shouldn't be an issue, and I note a couple spots where it lead to a bit of uncertainty.Run all commands as root. If at any point an uninstall command results in numerous 'dependent' packages also being designed for uninstallation, do not continue - that shouldn't happen.# clean up dnf just becausednf clean all# pull together a list of all installed rpmfusion packagesrpmflst=$(rpm -qa | grep rpmfusion)# for a sanity check, review that output; we're going to uninstall them allecho $rpmflst#now remove - only click 'y' if it looks reasonablednf remove $rpmflst# Double check for any stragglerscd /etc/yum.repos.d/ll# Delete any .repo files (or mv them somewhere like ~/ to be safe) EXCEPT these EDIT - was 3, now 4 - forgot google:#fedora.repo#fedora-updates.repo#fedora-updates-testing.repo#google-chrome.repo# install 'free'dnf install http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-23.noarch.rpm# install 'not-free'dnf install http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-23.noarch.rpm# The first repo should be the only one needed for vlc, but we will enable a couple others (for depdendencies) as rpmfusion is harmless (I couldn't test this as vlc is in the rawhide repo for F24 beta)dnf config-manager --set-enabled rpmfusion-free-updates-testing rpmfusion-free rpmfusion-free-updates-testing rpmfusion-nonfree rpmfusion-nonfree-updates rpmfusion-nonfree-updates-testing# Some of those enables could fail - if they are empty, etc. For that type of error keep on going# tidy updnf clean all# Download metadata (optional - its a check of the config without involving an install)dnf makecache# assuming you've had no GPG errors, try installing vlc nowdnf install vlcGPG Conflict Error ResolutionBasically we need to just delete the GPG keys that report conflicts. There is a clear guide at the link below, and since this isn't the topic of your question, and I'm sick of typing, I'll just point you to ithttps://blog.laimbock.com/2014/05/02/how-to-remove-an-imported-gpg-key-from-rpm/Once the offending GPG key is removed, you should be able to retry the step that failed and continue from there. If you subsequently get an error such as missing GPG key for repo XYZ, then edit the repository file (I can't find CLI option that persists), as follows:cd /etc/yum.repos.d/# Find the file that contains the offending repo config (e.g. rpmfusion-free-updates-testing)vi rpmfusion-free-updates-testing.repoFind the line where gpgcheck=1 and change to gpgcheck=0Now you should be able to continue on.
