Updates and Upgrades

Updated 2019-01-02

This article is intended for Fedora users.

Before installing any new software, always update:

dnf -y update

Backup your data files. To determine your current version, type:

cat /etc/*-release

To determine the current release from fedora, go to

https://getfedora.org/en/server/download/

dnf-plugin-system-upgrade (21 and later)  
Always upgrade only one version at a time  
For an upgrade of 28 to 29:
dnf -y update dnf -y install dnf-plugin-system-upgrade
dnf system-upgrade download –refresh  releasever=29 –allowerasing dnf system-upgrade reboot
     

Just tested this on an upgrade of Fedora 28 to 29. Worked well.
