fedora core 8 to fedora core 9 using iso DVD image.

start with obtaining

Fedora-9-i386-DVD.iso

and

mkdir -p /media/fedora

mount -o loop Fedora-9-i386-DVD.iso /media/fedora

then cd /media/fedora/Packages

[root@fedora Packages]# rpm -Uvh fedora-release-9-2.noarch.rpm  fedora-release-notes-9.0.0-1.noarch.rpm

then  tweak the /etc/yum.repos.d/fedora.repo

to have something as such ..

[fedora-dvd]
name=Fedora DVD
baseurl=file:///media/fedora
enabled=0
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora file:///etc/pki/rpm-gpg/RPM-GPG-KEY
then  run..

[root@fedora Packages]# yum –disablerepo \* –enablerepo fedora-dvd upgrade

it show some of the conflicting package..

remove those conflicting package..

except the one with python libssh2 libgnu

for libssh2 & libgnu

rpm -e –nodeps libssh2 libgnu

do not remove python

else your yum would’nt work anymore..

python is a bit tricky.. make sure you run yum update -y to the latest prior to upgrading..to get around the python-libs dependencies..

keep the old Fedora-8-i386.iso handy as well .. in case need to re-install old package.

i did accidentally removed python with

rpm -e –nodeps python python-libs

and after that yum is unusable until i do a

rpm -Uvh  python-2.5.1-15.fc8.i386.rpm python-libs-2.5.1-15.fc8.i386.rpm

yes.. grab that from the old FC8 dvd..

and yum  clean all

then try again

yum clean all

yum –disablerepo \* –enablerepo fedora-dvd upgrade python

this time succeed without any error then only I can perform full upgrade with..

yum –disablerepo \* –enablerepo fedora-dvd upgrade
