Fedora Repositorys und Programme hinzufügen

Vivaldi

sudo dnf install dnf-utils
sudo dnf config-manager --add-repo https://repo.vivaldi.com/archive/vivaldi-fedora.repo
sudo dnf install vivaldi-stable

Opera

By default, Opera Browser does not come included in the standard Fedora repositories. However, you can quickly create and import the official repository on your system by doing the following.

First, create and open up the repository file using any text editor:

sudo nano /etc/yum.repos.d/opera.repo

Next, copy and paste the following.

[opera]
name=Opera packages
type=rpm-md
baseurl=https://rpm.opera.com/rpm
gpgcheck=1
gpgkey=https://rpm.opera.com/rpmrepo.key
enabled=1

Once done, save the file CTRL+O then exit with CTRL+X.

Note, this will import the GPG key also for the installation. If the GPG fails to import for some reason, import it manually using the following command:

sudo rpm --import https://rpm.opera.com/rpmrepo.key
sudo dnf upgrade --refresh

Now install the software with the following command:

sudo dnf install opera-stable
