Hello guys,

I'm trying to upgrade my Fedora 22 to the recently released Fedora 23 and I'm having some problems related to low disk space. I'm following this tutorial to upgrade Fedora.

That's exactly what I'm trying to execute:

sudo dnf upgrade
sudo dnf system-upgrade download --releasever=23 // I'm getting stuck here
sudo dnf system-upgrade reboot

But then I have problem related to low disk space on /dev/mapper/fedora-root and the download process cannot proceed. The installation process take a lot of time and I'm tired of trying to install it, but if you need a detailed log I can run it again and paste the exactly problem here.

It's valid to remember that I'm using dual boot (Windows 8 and Fedora 22), so I don't have all of my space allocated to Fedora. However, I have lots of free space in Fedora (at least for /home/). Following you can check some commands that I had run in order to help you help me. :)

Do you need other details about my environment? What can I do to solve this problem and upgrade my system to Fedora 23?

Can you run baobab to find out what consumes all the space on your / partition? Are you running any servers on this system? Do you know why / is packed?

You can use "Disk Usage Analyzer" (Gui) to find the bigger folders in clicking and moving the mouse over coloured blocks. image description

1,7 Gib is definitely not enough for an upgrade.

You can clean some folders, examples :

  • sudo rm -fr /var/tmp/
  • sudo rm -fr /var/cache/yum.old/

Limit the size of your logs (/var/log/) :

  • sudo vi /etc/systemd/journald.conf and change the value to what you want : SystemMaxUse=500M

If you use a virtual machine (VirtualBox, Qemu...), you can move the images to your /home folder.

If you want to find all files > 500Mib, run : sudo find / -type f -size +500M

Thank you! I have almost 2.6GB free now. Do I need more free space to upgrade? If so, what else can I do in order to free more space?

@yolo can you help me?

A fresh install required at least 10Gb. For an upgrade, that depends on the number/size of packages installed. The dnf upgrade plugin you already ran, will inform you.

As @sideburns advised too, you need to find what takes so many rooms on /. You can use the Disk usage analyzer (I added a screenshot) of if you prefer the cli mode : ncdu or sudo du -h --max-depth=1 / | sort -h, find...

Have you virtual machines, big games, big apps? Not easy to tell you more, we don't have other elements.

I've found the problem! Thank you for the answer, it really helped me! :)

I've installed a lot of softwares in "/opt/" folder: KairosDB, Spark, Firefox, Chrome and specially Android SDK. The last one was sizing about 27GB!! As I don't need it anymore, I've uninstalled it and now I have more than 27GB of free space at /dev/mapper/fedora-root.

For the newcomers on Linux (like I'm), remember that /dev/mapper/fedora-root includes every folder at "/", excluding "/home/*". Thank you guys!

Install the program bleachbit, and run it from a terminal as root (sudo bleachbit) so that you have permission to delete files you don't own. You can use this to clean up temporary files, get rid of outdated log and backup files and otherwise clean up /. Be sure to have it clean up dnf and its database while you're at it. This may well be all that you need to do to have enough room for the upgrade. And while you're at it, you may want to ask yourself why / is so full in the first place, because you're almost out of room for your system to run.
