Upgrading Fedora

(2019-03-18)

Problem

I want to update Fedora to another version.

In General

It is recommended to upgrade to the next version and not skip versions.

Single-hop upgrades (27->28) are supported; double-hop upgrades (26->28) are supported for 30 days after the initial release, but in the majority of cases double-hop upgrades will probably work most of the time.

Fedora 27 -> 28

Ensure that the OS is as up-to-date as of now:

# dnf upgrade --refresh

Install the dnf plugin:

# dnf install dnf-plugin-system-upgrade

Stage the upgrade:

# dnf system-upgrade download --releasever=28

If issues are detected, you can try adding the --allowerasing flag to the command above; it will then erase RPMs that it cannot upgrade and conflict with the requested upgrade.

Perform a upgrade reboot:

# dnf system-upgrade reboot

This will take some time, but when the system comes back you should be running the requested upgrade version.
