I am testing the likelyhood of updating a couple RH9 systems to centos 5
386.
I found at document that talked about updating to centos 4. steps being:
1.) backup
2.)
rpm --import
http://pubmirrors.reflected.net/centos/5/os/i386/RPM-GPG-KEY-centOS-5
rpm -Uvh --nodeps
http://pubmirrors.reflected.net/centos/5/os/i386/CentOS/yum-3.0.5-1.el5.centos.5.noarch.rpm
rpm -i --nodeps --force
http://pubmirrors.reflected.net/centos/5/os/i386/CentOS/centos-release-5-1.0.el5.centos.1.i386.rpm
yum upgrade
Everything was progressing until I did tte "yum upgrade"
I got an error about not finding a yum package.
"There was a problem importing one of the python modules
required to run yum. The error leading to this problem was:
No module named yum"
What do I do now...
Thanks,
Jerry

Nodeps doesn't actually do any magic -- it just lets you install packages which may be broken once installed.> "There was a problem importing one of the python modules > required to run yum.

But I think you're going end up doing a huge amount of clean-up work after this project is completed even if it's successful. Better to back up your data and configuration, do a clean install, and then proceed with a nice fresh system. -- Matthew Miller mattdm at mattdm.org <http://mattdm.org/> Boston University Linux ------> <http://linux.bu.edu/>

Step 1, undo what has been done and never use a force or nodeps! Step 2, upgrade up2date to centos 3 (more on this when I find our notes) Step 3, update all packages which are not customized. Step 4, baby steps on customized configs/packages. ( you will need a lot of compat rpms to work with.) Step 5, get upgraded to 4, then 5 We have upgraded all of out 7.x and 9 systems to centos 4. Except one, it has sendmail, apache, etc incompatibilities.> -----Original Message----- > From: centos-bounces at centos.org [mailto:centos-bounces at centos.org] On > Behalf Of Jerry Geis > Sent: Friday, May 02, 2008 2:47 PM > To: CentOS ML > Subject: [CentOS] RH9 to centos 5 386 > > I am testing the likelyhood of updating a couple RH9 systems to centos 5 > 386. > I found at document that talked about updating to centos 4. steps being: > 1.) backup > 2.) > rpm --import > http://pubmirrors.reflected.net/centos/5/os/i386/RPM-GPG-KEY-centOS-5 > rpm -Uvh --nodeps > http://pubmirrors.reflected.net/centos/5/os/i386/CentOS/yum-3.0.5- > 1.el5.centos.5.noarch.rpm > rpm -i --nodeps --force > http://pubmirrors.reflected.net/centos/5/os/i386/CentOS/centos-release-5- > 1.0.el5.centos.1.i386.rpm > yum upgrade > > Everything was progressing until I did tte "yum upgrade" > I got an error about not finding a yum package. > > "There was a problem importing one of the python modules > required to run yum.
