I killed my old Linux, then I installed new, now I have problems to install some programs I had before. Before I made some backup, like the .bash_history where I can see, that it worked already.
Now when I type sudo dnf install mkv or sudo dnf install ffmpeg
I get only the message, that this package is not available. I made the update/upgrade and updated the rpmdb but there is no change to see. What can I do to provide this features?
OS: Fedora 25
