I just did an upgrade of my old desktop from Fedora 20 to Fedora 21. The process was similar to this old blog post, but there were some variations, so I’ll list the procedure here.
- Update your current Fedora 20 system by issuing the “yum update -y” command and restart once it is complete.
- Install the latest “fedup” package using “sudo yum –enablerepo=updates-testing install fedup”
- Run the “sudo fedup-cli –network 21 –product=nonproduct” command.
- If you are using Dropbox, disable the repository using the “yum-config-manager –disable Dropbox” command. Re-enable it once the Fedora 21 repository is available.
- Run the following clean up commands.
sudo rpm --rebuilddb sudo yum distro-sync --setopt=deltarpm=0 sudo yum install rpmconf sudo rpmconf -a
- If you are using Chrome, uninstall and reinstall Chrome.
It seemed to go fine!
