Just a PSA for everyone who’s running Fedora, EOL is coming up for Fedora 25. You can upgrade to Fedora 27 using dnf whenever you get a moment. The process is outlined below.
Upgrading to fedora 27
Before you do any package changes to a Linux system, it’s best practice to make sure your system is up to date on the current release.
sudo dnf upgrade --refresh
Once that’s done, you can install the system upgrade plugin.
sudo dnf install dnf-plugin-system-upgrade
Once you’ve got the requisite packages installed, you can pre-fetch all the packages needed to do the upgrade.
sudo dnf system-upgrade download --releasever=27
Finally, reboot into upgrade mode to do the release upgrade.
sudo dnf system-upgrade reboot
The system will reboot and start running the upgrade. On my laptop, this took about an hour, with about 4500 dnf operations. I would recommend stepping out for a while since the system will be unusable during this period.
