Upgrade to Zorin 17 error

In running the Zorin OS Upgrader, I get an onscreen error:

In checking syslog:
CheckingForUpgrades.vala:73: GDBus.Error:org.gtk.GDBus.UnmappedGError.Quark._g_2dio_2derror_2dquark.Code14: Error: sender not authorized

Is there something I may have incorrectly configured to see these errors?

This error looks like the server for Vala is not responding. Do you have Vala installed on Zorin OS 16?
You might uninstall Vala and remove its repository. Then run the Zorin OS Upgrader. If it successfully completes, remember to install Vala from a Jammy repository afterward.

Nope... Do not have Vala installed.

Can you please post the terminal output for

We have similar tastes...:stuck_out_tongue:

I can see Brave Browser and Mono both listed there. Both of these require a GPG key added with the repo - I notice in two other active threads that this has caused issues with the Direct Upgrade option.

I also do not see Vala listed. Can you please double check your sources.list?

I see nothing amiss there...

Zorin OS 17 includes a Flatpak package for Firefox instead of APT. There are several reasons for this and a lot of discussion and this may be changing to a standard APT package for Firefox in the future.
However, in the meantime:

I wonder if the upgrader command flatpak remote-add --gpg-import=gnome-firefox.gpg gnome is causing that error.
If it tries to set this up as remote; it will need polkit authentication.

I do not have an immediate answer for this...

Out of my league... Just as an FYI, under Setting> Users, I appear to be unable to unlock any setting to change any respective settings, which also requires a policy change.

I will wait for any further info...

Are you the person who installed Zorin OS?

Did you have any user permissions prior?

Is Zorin OS installed on an external drive?

Yep... I installed ZOs...
Never really looked at the Users setting since I have root capabilities.
ZOs is installed internally on a dual boot system from a time when I did use Windows... I do not anymore.

From the screenshot above, the image looks normal. If you click the "Unlock" option, you should be able to access changing settings.

The unlock 'verbiage' is there, but it is not a button (clickable).

Please see the upper right side: There is a button that says "Unlock."

I must point out that this button in the theme lacks any border or indication that it is a button...
But using one of my own themes, it is bordered with the Button Theme.

I understand what you are referring to and in changing to a different theme, I can see the border...

That said, it is NOT a clickable button/link.

I am not sure on this. Maybe a regular Gnome User can chime in.

I have only one account, yet the button is clickable. It leads to an authentication window to enter the sudo password.

Do you have autologin enabled?

It is tangental (albeit possibly connected?) to the original upgrade issue, but if someone has an answer, that would be great!

I was so focused on the button, I completely forgot about the failed upgrade.

If the upgrade failed without proceeding, then it would not have broken packages due to nothing being overwritten. But, if you had a partial upgrade, that could break packages.

That is/was the issues... there is no upgrade (failed or otherwise...) available due to the error.

In a quick 'inspector gadget' style troubleshooting, I am going to try removing chrome-remote-desktop and see how that affects the settings issue (Button Unlock is greyed at the settings users on ubuntu 20.04 - Stack Overflow).

My spidey sense is tingling and I hope this may help the upgrade issue as well.

EDIT: Confirmed. It appears that chrome-remote-desktop and polkit specifics involved has a negative affect on the OS-Upgrader.


The upgrade process happend, but alas, issues happened. It appears that an install of OpenCV disrupted the install with some broken packages. Having fixed that, apt proceeded to update a number of items except for the kernel...

How to best update the kernel to 6.2?
