In my usual disorganized fashion, I don’t use the same Fedora remix on the desktop and laptop, but Korora on one and Chapeau on the other. Why fedora? Well, it is more up to date than Debian — though I have an old laptop running Crunchbang plus plus , but on faster machines I find fedora works better, and allows me to run my /home directory easily over two SSDs. Anyway, Fedora 23 is out, and these distros are heading into beta.

And I hate reinstalling… so in Chapeau:

sudo dnf update --refresh
#Needed. Or else you will have conflicts when you get down to the next step.
sudo dnf system-upgrade download --releasever=23

(Skipping the download)

Complete!
Download complete! Use 'dnf system-upgrade reboot' to start the upgrade.
The downloaded packages were saved in cache till the next successful transaction.
You can remove cached packages by executing 'dnf clean packages'.

However, in Korora I have problems. My install fo Korora is modified. I have dropbox up, and I have other repos. I have upgraded this before. Using this technique I get.

 sudo dnf system-upgrade download --releasever=23

(try to add '--allowerasing' to command line to replace conflicting packages)

Modifying the command as suggested works.

sudo dnf system-upgrade download --releasever=23 --allowerasing

This is not as quick as doing this on ubuntu. And yes, it requires command line skills. But is saves me burning disks and USBs, and it keeps all the modifications I have made intact. So… recommended.

Now to get cinnamon working, or Xfce, on Chapeau…
