How to upgrade to Fedora 24 using gnome-software gui
The official way to upgrade Fedora is using the dnf system-upgrade plugin, on the command line.
Now, there seems to be a new way of upgrading to the latest Fedora release, using the graphical software tool called "gnome-software". According to an article in the Fedora magazine, it should be possible to upgrade a Fedora 23 system to Fedora 24 using this tool.
This program does show this message "Fedora 24 ready to be installed" and after clicking "Download", the "Install" button is visible. However, after clicking on "Install" and entering the password, nothing happens.
How can this be debugged? How do you find out what went wrong?
The following line is printed when the "Install" button is clicked - if gnome-software
is run in a terminal:
(gnome-software:20737): Gs-WARNING **: Calling org.gnome.SessionManager.Reboot failed: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SessionManager was not provided by any .service files
Clarification: The main question is "how to find out what went wrong", i.e., "get the error message" because clicking on "Install" did absolutely nothing.
Now, after running a regular system update (dnf update
) and trying it again, the program has shown an error message - for the first time ever - rather than simply doing nothing, leaving the user in the dark. In this case, it couldn't "download" a file from file:///var/cache/PackageKit/24/metadata
. Maybe the error handling has been improved in the meantime.
