Hi, This question comes up every year or two. We haven't made it into a web page because we don't want to make it look like we are trying to take away RedHat's business.Updating from RHEL5 to SL5 is easier than it is to update from RHEL4 to SL4. This is because RHEL5 has yum, while RHEL4 is using up2date. I *believe* the easiest way would be to change up2date to point to scientific linux, and then use it to install yum and the first updates. 1 - Edit /etc/sysconfig/rhn/sources and comment out the line up2date default and add the lines yum fermi-base http://ftp1.scientificlinux.org/linux/scientific/4x/$ARCH/SL/RPMS/ yum fermi-errata http://ftp1.scientificlinux.org/linux/scientific/4x/$ARCH/errata/SL/RPMS/ 2 - Install yum using up2date up2date install yum up2date install yum-conf 3 - install sl-release using yum yum install sl-release 4 - Update everything else yum update You may run into problems with this, but I currently don't have the infrastructure to test this out, so I am not sure what problems you will run into. But that is the general idea. Get yum on the system, then update sl-release, and then update everything else. Troy
For the most part, the above instructions worked perfectly - save for up2date complaining about GPG signatures. I added --nosig and it worked great (livin on the edge!).. How would I have installed the gpg signature?
Also, do you mind if I publish these instructions on the web? (I can give credit, or not - depending upon what you prefer).. I know you don't want it to look like you're trying to cannabalize RHEL but this helps smaller vendors or university groups who don't have the resources for a full RHEL support license.
Also, thank you kindly for all the work you do on SL! Thanks, ~Chris
