The Nux repository brings a set of additional packages available at least for RHEL 7 and CentOS 7.
This is the best place to find desktop and multimedia oriented RPMs.
There is a list of the available packages in the Nux repository.
To install the Nux repository, you need to install the EPEL7 repository then type:
# yum install -y http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-1.el7.nux.noarch.rpm
The Nux repository consists of 2 different channels:
- nux-dextop: this is the main channel; it is enabled by default,
- nux-dextop-testing: it is a channel used for testing; it is disabled by default.
To permanently enable a channel (use the –disable option to disable), type:
# yum-config-manager --enable channel
To only enable a channel during a package installation, type:
# yum --enablerepo=channel install package
