Thunar Plugin Not Working

Hi there

I’m running Xubuntu 22.04.1 LTS x86_64 and have installed the InSync Thunar plugin but it doesn’t work. Here’s the error:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python3/dist-packages/gi/__init__.py", line 126, in require_version
    raise ValueError('Namespace %s not available' % namespace)

Is there any way to fix this?

Hi @ShayneOConnor! Thanks for reaching out about this, and my apologies for the trouble!

Let me forward the issue to our Linux engineer and I’ll update this thread once I have more information.

Hi @ShayneOConnor

Can you try installing this package?

sudo apt install libthunarx-3-0

Installing libthunarx-3-0 gives this error message when trying to run Thunar:

Gtk-Message: 09:38:00.755: Failed to load module "xapp-gtk3-module"
And Thunar won’t run at all.

Then the following packages are installed:
thunarx-python
insync–thunar
libthunarx-3-0

Edit: Added more info

Hi,
I’ve the same problem with a fresh linux Mint 21 Vanessa. Installing insync-thunar lead to a complete failure of thunar. Purging insync-thunar resolved the situation and thunar is working again.

Thank you for sending the output my way, and apologies for the experience, @obscura59!

I’ll have our engineer investigate the info you sent, and I’ll update you should we need more information.
