There are two main ways to upgrade Fedora 10 (Cambridge) to Fedora 11 (Leonidas):
» What the Fedora developers suggest:
yum -y upgrade yum -y install preupgrade yum clean all preupgrade-cli "Fedora 11 (Leonidas)"
Of course, if you’re doing this on a Fedora desktop, you can use
preupgrade (rather than preupgrade-cli) to upgrade with a GUI.
» The method I prefer (and it works properly on Slicehost):
yum -y upgrade yum clean all wget http://download.fedora.redhat.com/pub/fedora/linux/releases/11/Fedora/x86_64/os/Packages/fedora-release-11-1.noarch.rpm rpm -Uvh fedora-release-11-1.noarch.rpm
At this point, you would normally just start upgrading packages, but the Fedora developers threw us a curveball. Since yum in Fedora 10 doesn’t support metalinks, your upgrades will fail with something like this:
# yum -y upgrade YumRepo Error: All mirror URLs are not using ftp, http[s] or file. Eg. / removing mirrorlist with no valid mirrors: //var/cache/yum/updates/mirrorlist.txt Error: Cannot retrieve repository metadata (repomd.xml) for repository: updates. Please verify its path and try again
It’s easily fixed, however. Open up
/etc/yum.repos.d/fedora-updates.repo in your favorite text editor and change the
mirrorlist URL’s like so:
Fedora Updates Repository
Once you make those changes, finish out the upgrade:
yum -y upgrade
This process will take a little while to complete, but there shouldn’t be any interaction required. Once it’s done, change the
mirrorlist lines back to the original values so you can benefit from the speedups provided by the metalink format.
