Software and Updates starts, it just fails to find a distribution template for PureOS

I believe this is the same problem as T660. In my case, this application does not launch. Fortunately, I do not use it very much.

Grrr, this means a distro patch to python-qpt got reverted in PureOS somehow.
I will have a look, thanks for the direct bug assignment!

I was commenting on a PureOS forum topic, and I discovered the same error when using Software->left application icon->Software Repositories. My system log file displayed the above stack.

I assume Software uses the same utility to find the repositories. This is probably not a revelation, but it is another data point.
