I recently switched to Kubuntu 17.04 it's amazing but I didn't like dolphin (file manager that comes with KDE suite), so I tried to install Nautilus by doing This
sudo add-apt-repository ppa:gnome3-team/gnome3 sudo apt-get update && sudo apt-get install nautilus
This should have installed Nautilus but it gave me an error
W: The repository 'http://ppa.launchpad.net/docky-core/stable/ubuntu zesty Release' does not have a Release file. N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use. N: See apt-secure(8) manpage for repository creation and user configuration details. E: Failed to fetch http://ppa.launchpad.net/docky-core/stable/ubuntu/dists/zesty/main/binary-amd64/Packages 404 Not Found E: Some index files failed to download. They have been ignored, or old ones used instead.
What does this actually mean? Will I not be able to install Nautilus in Kubuntu 17.04?
