Error Problem conflicting requests - nothing provides epel-release = 7 needed by remi-release-79-5el7reminoarchtry to add --skip-broken to skip uninstallable packages or --nobest to use not only bes

Solution: This error message indicates that there is a conflict between the packages that are being installed. Specifically, the package "remi-release-7.9-5.el7.remi.noarch" requires "epel-release = 7" to be installed, but this version of "epel-release" is not available.

To resolve this issue, you can try the following steps:

1. Check if the "epel-release" package is already installed on your system by running the command:

   sudo yum list installed epel-release

   If this package is already installed, you can try updating it to the required version by running:

   sudo yum update epel-release

2. If the "epel-release" package is not installed, you can try installing it using the following command:

   sudo yum install epel-release

3. Once the "epel-release" package is installed or updated, you can try installing the "remi-release" package again by running:

   sudo yum install remi-release

   This time, the package should be installed without any conflicts.

If none of these steps work, you can try adding the "--skip-broken" option to the installation command to skip the installation of any conflicting packages. However, this may result in incomplete dependencies and may cause issues with the functionality of the installed software. Therefore, it is recommended to try the above steps first before resorting to this option.
