Software & Updates application crashed when tried to sign in - clicking the Sign in / Register button in the popup window. Furthermore, the "Other Software" tab doesn't change on clicking any of the records - the window greys out as it was bringing up a (root password) popup as expected but nothing happens, another click and it's back to normal without any change.

Running the application from the terminal (with sudo to bypass the secondary issue above) the application runs fine the "Other Software" tab acts as expected but again the Livepatch sign in break the same way with the error:

```
$ sudo software-properties-gtk

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

Thank you for your bug report, could you start it from a command line without sudo? Graphical softwares are not meant to be used under sudo and that's normal it's not working this way

This happened to me following driver upgrade via apt. I forgot to reboot after doing the upgrade, probably the old driver version was still registered instead of the new version or something (I have no clue how this works). Rebooting solved it.
