A plugin for DNF that does fedup-style upgrades using systemd's Offline Updates facility.
make install
To download everything needed to upgrade to Fedora 23:
# dnf system-upgrade download --releasever=23
Once that finishes, you can begin the upgrade process:
# dnf system-upgrade reboot
There's also a fedup-compatible wrapper script, so this works too:
# fedup --network 23
# fedup reboot
Everything printed by dnf during the upgrade is in the system journal.
Run dnf system-upgrade log to see a list of boots during which an
upgrade was attempted. Use dnf system-upgrade log [NUM], where
[NUM] is usually -1, to see the logs for that boot using journalctl.
If you'd like a root shell available during the upgrade, add
systemd.debug-shell to your boot arguments.
You can also enable the shell for all system updates/upgrades:
# systemctl add-wants system-update.target debug-shell.service
Switch to the shell with Ctrl-Alt-F9 and back to the upgrade progress with Ctrl-Alt-F1.
If the system gets stuck at system-update.target without starting the
upgrade, remove /system-update to make the system boot normally.
If you don't have the debug shell available, you can use the dracut emergency
shell; add rd.break to the boot args, then:
# mount -o remount,rw /sysroot
# rm /sysroot/system-update
Exit the shell and your system should start normally.
Problems can be reported through
or through
- the Fedora bug tracker — upgrade problems and integration with the rest of the distribution: new bug.
Please include /var/log/dnf.log and the output of
dnf system-upgrade log -1 (if applicable) in your bug reports.
Problems with dependency solving during download are best reported to the maintainers of the package(s) with the dependency problems.
Similarly, problems encountered on your system after the upgrade completes should be reported to the maintainers of the affected components. In other words: if (for example) KDE stops working, it's best if you report that to the KDE maintainers.
