Pre-Upgrade Procedure

  • Install (if necessary) 
yum install yum-utils
  • Run: 
yum update
rpm --rebuilddb
yum clean all
  • Run the following: 
for a in $(find /etc /var -name '*.rpm?*'); do b=${a%.rpm?*}; diff -u -q $a $b; done
and resolve conflicts
  • Look for orphaned packages and remove as appropriate 
package-cleanup --orphans
  • Check /etc/grub.conf
  • Reboot

Upgrade Procedure

  • as root run: 
rpm -Uhv ftp://download.fedora.redhat.com/pub/fedora/linux/releases/7/Fedora/i386/os/Fedora/fedora-release-*.noarch.rpm
  • Upgrade the OS via yum: 
yum -y --obsoletes update
I kept getting "Metadata file does not match checksum" errors in the above step. Following the advice at [1], I ran "yum clean all", "yum makecache" and then "yum update" and then resumed and I think things are OK. --Von 11:29, 11 September 2008 (CDT)
  • Ensure all essential packages from the new version are installed: 
yum groupupdate Base
I got a "No Package Matching glibc.i686" error when I did this. Following the advice at [2], I did a "yum update glibc" and then tried again and it seemed to work. --Von 11:31, 11 September 2008 (CDT)
  • Run the following: 
for a in $(find /etc /var -name '*.rpm?*'); do b=${a%.rpm?*}; diff -u -q $a $b; done
and resolve conflicts
  • Look for orphaned packages and remove as appropriate 
package-cleanup --orphans
  • Check /etc/grub.conf
  • Reboot

Post-Upgrade Procedure

  • After reboot, check uname -a and remove any old fc6 kernels, then double check /etc/grub.conf
  • Run through this document to ensure the VM still conforms to the standard configuration 
http://mywiki.ncsa.uiuc.edu/wiki/Server_Installation
  • If this is a mediawiki, the kerberos authentication will break. To fix: 
sudo su -   (to root)
cd
rm -rf pam_auth/
rm -rf pam_auth-0.4-4.3.tar.gz
cd /usr/lib/php/modules
rm pam_auth.so
pecl install PAM 
nano /etc/php.ini
change
extension=pam_auth.so
to 
extension=pam.so

Troubleshooting

Missing Dependencies

If you get: 

Error: Missing Dependency: python(abi) = 2.4 is needed by package rhnlib
Error: Missing Dependency: python-optik is needed by package up2date
Error: Missing Dependency: python(abi) = 2.4 is needed by package up2date
Error: Missing Dependency: python(abi) = 2.4 is needed by package 4Suite
Error: Missing Dependency: python-abi = 2.4 is needed by package 4Suite

then 

rpm -e rhnlib up2date 4Suite

You can reinstall 4Suite using "yum install python-4Suite-XML" after the upgrade

Shibboleth Dependencies

I also got the missing dependencies below on computer.ncsa.uiuc.edu, which I believe come from Shibboleth ultimately. I'm guessing I need to back Shibboleth out first. 

Error: Missing Dependency: libcurl.so.3 is needed by package opensaml
Error: Missing Dependency: python(abi) = 2.4 is needed by package authconfig

Possible error with python

  • If you get 
--> Running transaction check
--> Processing Conflict: python-devel conflicts python < 2.4.4-1.fc6
--> Finished Dependency Resolution
  • Do the following as root 
rpm -qa | grep python
  • Look for multiple versions of python 
python-2.4.4-1.fc6
python-2.4.3-18.fc6
python-devel-2.4.3-18.fc6
  • Remove the version that does not match python-devel 
rpm –e python-2.4.4-1.fc6
yum update
