Status changed to 'Confirmed' because the bug affects multiple users.

[martyfelker (martyfelker-gmail)]

Affect me. Ubuntu Trusty. I can't update anymore and need to solve urgently

[James Plate (james-plate-deactivatedaccount)]

This has affected me as well, the following is an excerpt from the result of today's dist-upgrade:

[Gary Allpike (garyallpike)]

To fix this:

You can edit the file:

/usr/share/screen-resolution-extra/nvidia-prime.py

Find line 64 which looks like:

        except dbus.exceptions.DBusException, e:

and change it to:

        except dbus.exceptions.DBusException as e:

This should resolve the problem.

Cheers!

Downloaded the screen-resolution-extra_0.16.orig.tar.gz tarball, which I believe was the version indicated, and it worked with just a simple "sudo ./setup.py install" away from working. Already fixed?

[Gary Allpike (garyallpike)]

The problem is not with setup.py.

The error is in the nvidia-prime.py script.

I have checked the source tarball and the error is also present there.

[cacula (cacula)]

This is how i fixed it:

- sudo nano /usr/share/screen-resolution-extra/nvidia-prime.py
- Apply the changes proposed by garyallpike in Post #7 -> Thank you :-)
- Save the file
- sudo dpkg --configure screen-resolution-extra

Cheers!

[cacula (cacula)]

It's not Post #7 but rather #6. Sorry.

[ubername (ubername)]

Thanks, fixed using above. How would I have found out the syntax for dbus.exceptions.DBusException myself?

[Gary Allpike (garyallpike)]

It's actually not a syntax error related to dbus.exceptions.DBusException, but rather an error in the syntax of the python exception handler syntax.

I looked at the output of dpkg when it tried to configure the package:

----

  File "/usr/share/screen-resolution-extra/nvidia-prime.py", line 64
    except dbus.exceptions.DBusException, e:

dpkg: error processing screen-resolution-extra (--configure):
 subprocess installed post-installation script returned error exit status 1
----

and saw the above.

I have no python-fu at all, I simply googled for "python except" and clicked on the first result :)

Cheers!

[Cavsfan (cavsfan)]

Thanks post #6 fixed this error for me too.
It was able to setup screen-resolution-extra.

[Launchpad Janitor (janitor)]
