I am using Jiffybox for developing and testing. It easy to create a new virtual machine, and start from fresh again.

Unfortunately, Fedora 22 is not available yet. See for details: https://www.df.eu/forum/threads/76789-Update-auf-Fedora-22

For the moment, the only way is to upgrade your Jiffyboxes from Fedora 21 to Fedora 22. Fedup does not work, because of the kernel image.

IOError: [Errno 2] No such file or directory: '/boot/initramfs-3.18.9-x86_64-jb1.img'

The solution is to use yum distro-sync.

There is another problem with the firewalld package:

Fehler: Paket: firewalld-config-standard-0.3.14.2-2.fc21.noarch (@updates/21)
            Benötigt: firewalld = 0.3.14.2-2.fc21
            Entfernen: firewalld-0.3.14.2-2.fc21.noarch (@updates/21)
                firewalld = 0.3.14.2-2.fc21
            Aktualisiert durch: firewalld-0.3.14.2-2.fc22.noarch (updates)
                firewalld = 0.3.14.2-2.fc22
            Verfügbar: firewalld-0.3.13-7.fc22.noarch (fedora)
                firewalld = 0.3.13-7.fc22

So these are the commands that work for me:

rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-22-$(uname -i)
yum update yum
yum clean all
# avoid problems with yum not being able to resolve firewalld upgrade
yum remove firewalld
yum --releasever=22 distro-sync
Fedora 22 on Jiffybox
