Switch from centos 4 to SL4?
Hello All, My google foo is apparently not good enough to find a page that might describe the process of switching from centos4 to SL4.. Does anyone know of a good HOWTO or tutorial about this? Thanks, ~Chris

I would like it to identify as Scientific Linux, and use the Scientific Linux repos for regular updates - reinstall sounds like I may have to burn an ISO...? Thanks, -Chris

Thanks, -Chris If you just want to switch a running system, I *think* this would be all you need to do. 1 - Point Yum to look at SL yum repositories 1a - rm -f /etc/yum.repos.d/*repo (a bit drastic, but if you want to go slow, just move everything) 1b (SL5) - rpm -Uvh http://ftp.scientificlinux.org/linux/scientific/5x/i386/misc/RPMS/yum-conf-latest.SL.noarch.rpm 1b (SL4) - rpm -Uvh http://ftp.scientificlinux.org/linux/scientific/4x/i386/misc/RPMS/yum-conf-latest.SL.noarch.rpm 2 - Replace the following packages: yum (from centos) -> yum (from SL) centos-release -> sl-release centos-release-notes -> sl-release-notes (SL5 Only) 2a - yum clean all (or even better 'rm -rf /var/cache/yum') 2b - yum update yum 2c - yum install sl-release\* 3 - Do a yum update, cleaning up the rest of the stuff. Note: I have not done or tried this. But it seems logical. Troy -- __ Troy Dawson daw...@fnal.gov (630)840-6468 Fermilab ComputingDivision/LSCS/CSI/USS Group __

Hi All, first of all, thanks for the help. If you just want to switch a running system, I *think* this would be all you need to do. 1 - Point Yum to look at SL yum repositories 1a - rm -f /etc/yum.repos.d/*repo (a bit drastic, but if you want to go slow, just move everything) 1b (SL4) - rpm -Uvh http://ftp.scientificlinux.org/linux/scientific/4x/i386/misc/RPMS/yum-conf-latest.SL.noarch.rpm Done. 2 - Replace the following packages: yum (from centos) -> yum (from SL) centos-release -> sl-release centos-release-notes -> sl-release-notes (SL5 Only) I cannot seem to install yum: I get dependency errors: # rpm -i yum-2.4.3-10.SL.noarch.rpm warning: yum-2.4.3-10.SL.noarch.rpm: V3 DSA signature: NOKEY, key ID 82fd17b2 error: Failed dependencies: python-elementtree is needed by yum-2.4.3-10.SL urlgrabber is needed by yum-2.4.3-10.SL So I attempt to follow the dependency trail, and end up stalled at: # rpm -i yum-2.4.3-10.SL.noarch.rpm python-2.3.4-14.7.el4.i386.rpm python-elementtree-1.2.6-4.i386.rpm urlgrabber-2.9.6-1.noarch.rpm warning: yum-2.4.3-10.SL.noarch.rpm: V3 DSA signature: NOKEY, key ID 82fd17b2 warning: python-elementtree-1.2.6-4.i386.rpm: V3 DSA signature: NOKEY, key ID a7048f8d error: Failed dependencies: libdb-4.2.so is needed by python-2.3.4-14.7.el4 As far as I can tell, libdb-4.2 is provided by the package compat-db in SL5, however, the latest version in SL4 is < 4.2... (I am attempting to convert to SL4) Am I missing something here? Previously I had converted this system from EL4 to Centos4 - might this have something to do with it? Thanks again! -Chris

EL4 never had yum, or the libraries for yum. Centos 4 had yum, so I had assumed that you had yum installed already. Right at the moment I don't have time to track down which packages, maybe someone else had the list of packages needed for yum to be installed on a EL4 machine?
