RimFrost, we need more information. How were you trying to update, using zypper, yast, or other? What was the output before the dbus message? What version of openSUSE were you trying to update and to what? Be verbose, we can filter out what isn’t needed. Many tend to bypass messages that don’t have relevant info.
If you have read my signature you had known what openSUSE version i run. It stands there.
To start with, it seems that the updater applet cant scan/download updates.
It tells me that there is updates available for the system and when i click the icon for the updater applet and try to start update the message starts to appear as i told you. I did try to restart the system to see if there where any more messages that came, but no only this:
DBus error : Unable to get transaction id from packagekit.
And there isnt any other messages!
It just tells me the message above when i click the updater applet icon and will try to start update the system.
I have post the rong message from the updater applet exactly as it appears.
If it had been more messages i had posted them.
Just a passing thought: sometimes over the years in various versions of openSUSE when the updater applet plays up for me I use yast instead and that seems to fix the situation. I goto Yast → software → online update and run it from there. Then the applet seems to correct itself.
Maybe that will fix it for you, maybe it won’t, worth a try.
