The application cannot be installed due to an unavailable repository for DNF

Problem

When installing the application on a computer running the CentOS operating system, you see a message stating that the repository for the DNF software package manager is not available. Application installation is interrupted.

Solution

The application cannot be installed if the repositories containing the installation packages for the operating system are unavailable (or incorrectly configured) in the DNF software package manager. To install the application, unavailable repositories must be disabled.

To disable unavailable repositories and install the application:

1. Load the list of all connected repositories of the DNF package manager. To do so, open the operating system console and type the following command in the command line:

   dnf repolist

2. Find the unavailable repositories on the list and disable them. To disable a repository, type the following command in the command line:

   sudo dnf config-manager --set-disabled <repository name>

3. Reinstall the application with the same installation settings.
