I receive the following error message when starting yumex after installing the linva repository. failure: repodata/repomd.xml from livna: [Errno 256] No more mirrors to try. http://rpm.livna.org/repo/23/i386/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found http://ftp-stud.fht-esslingen.de/pub/Mirrors/rpm.livna.org/repo/23/i386/r...: [Errno 14] HTTP Error 404 - Not Found ftp://mirrors.tummy.com/pub/rpm.livna.org/repo/23/i386/repodata/repomd.xml: [Errno 14] FTP Error 550 - Server denied you to change to the given directory http://wftp.tu-chemnitz.de/pub/linux/livna/repo/23/i386/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found You can try starting 'yumex -n' from a command line and deselecting the repositories causing problems and try again. Running yumex -n --root from the command line works. Thanks.
