We recently installed CentOS 7 from DVD. Our install selection was the GNOME desktop option. yum update yielded about 465 megabytes of updates all of which were successful with no warnings. The multi media option was not chosen because KDE was listed. GNOME was not apparent in the software list for the multi media workstation install. Google searches led us to instructions for installing mplayer. The repo update appears to be successful as indicated below. Dependency resolution at the time of mplayer installation yielded twelve errors. Are there other packages that could be installed prior to another attempt at mplayer installation that might provide the missing items? Might these errors have been avoided by choosing the multi media workstation install? Thanks. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ [user at computer ~]$ yum repolist Loaded plugins: fastestmirror, langpacks Determining fastest mirrors * base: centos-distro.cavecreek.net * epel: mirrors.sonic.net * extras: centos-distro.cavecreek.net * nux-dextop: mirror.li.nux.ro * updates: centos-distro.cavecreek.net repo id repo name status base/7/x86_64 CentOS-7 - Base 10,019 epel/x86_64 Extra Packages for Enterprise Linux 7 - x86_64 13,237 extras/7/x86_64 CentOS-7 - Extras 419 nux-dextop/x86_64 Nux.Ro RPMs for general desktop use 1,603 updates/7/x86_64 CentOS-7 - Updates 2,137 repolist: 27,415 [user at computer ~]$ --> Finished Dependency Resolution Error: Package: mplayer-1.1-33.20150505svn.el6.nux.x86_64 (nux-dextop) Requires: libgnutls.so.26()(64bit) Error: Package: ffmpeg-libs-2.6.8-3.el6.nux.x86_64 (nux-dextop) Requires: libopenjpeg.so.2()(64bit) Error: Package: mplayer-1.1-33.20150505svn.el6.nux.x86_64 (nux-dextop) Requires: libcdio.so.10()(64bit) Error: Package: mplayer-1.1-33.20150505svn.el6.nux.x86_64 (nux-dextop) Requires: libcdio_cdda.so.0(CDIO_CDDA_0)(64bit) Error: Package: librtmp-2.4-0.3.20110811gitc58cfb3e.el6.nux.x86_64 (nux-dextop) Requires: libgnutls.so.26()(64bit) Error: Package: ffmpeg-libs-2.6.8-3.el6.nux.x86_64 (nux-dextop) Requires: libgnutls.so.26()(64bit) Error: Package: faac-1.28-2.el6.nux.x86_64 (nux-dextop) Requires: libmp4v2.so.0()(64bit) Error: Package: mplayer-1.1-33.20150505svn.el6.nux.x86_64 (nux-dextop) Requires: libcdio_paranoia.so.0()(64bit) Error: Package: ffmpeg-libs-2.6.8-3.el6.nux.x86_64 (nux-dextop) Requires: libgnutls.so.26(GNUTLS_1_4)(64bit) Error: Package: mplayer-1.1-33.20150505svn.el6.nux.x86_64 (nux-dextop) Requires: libcdio_paranoia.so.0(CDIO_PARANOIA_0)(64bit) Error: Package: librtmp-2.4-0.3.20110811gitc58cfb3e.el6.nux.x86_64 (nux-dextop) Requires: libgnutls.so.26(GNUTLS_1_4)(64bit) Error: Package: mplayer-1.1-33.20150505svn.el6.nux.x86_64 (nux-dextop) Requires: libcdio_cdda.so.0()(64bit) You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles --nodigest [root at root user]#
