It seems everybody is out of ideas why yum is not updating the kernel. The following kernels are installed in /boot: vmlinuz-2.6.18-8.1.14.el5 vmlinuz-2.6.18-8.el5 I originally installed CentOS 5.0 via CD. Yum automatically updated to 5.1 including kernel-2.6.18-8.1.14.el5. I have traced the kernels from kernel-2.6.18-8.el5 to kernel-2.6.18-8.1.14.el5. Yum stopped updating at this point. kernel-2.6.18-8.1.14.el5 was installed Oct 10, 2007 according to yum.log. It seems I installed rpmforge.repo around October 13, 2007. The installation included two files. rpmforge.repo and mirrors-rpmforge. The contents of rpmforge.repo is: # Name: RPMforge RPM Repository for Red Hat Enterprise 5 - dag # URL: http://rpmforge.net/ [rpmforge] name = Red Hat Enterprise $releasever - RPMforge.net - dag #baseurl = http://apt.sw.be/redhat/el5/en/$basearch/dag mirrorlist = http://apt.sw.be/redhat/el5/en/mirrors-rpmforge #mirrorlist = file:///etc/yum.repos.d/mirrors-rpmforge enabled = 1 priority = 99 protect = 0 gpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmforge-dag gpgcheck = 1 Other than the priority is not needed, does any of the previous ring a bell? Still frustrated. I received the following this morning: /etc/cron.daily/yum.cron: Error: Cannot find a valid baseurl for repo: base Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=5&arch=i386&repo=os error was [Errno 14] HTTP Error 505: DNS lookup error Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=5&arch=i386&repo=os error was [Errno 14] HTTP Error 506: Failure To Connect To Web Server Has CentOS.org changed their url? -- Bob Taylor _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
