another SW version conflict

[Stan Schymanski]

Dear Daniel,

I am again getting a version conflict for 2 packages with the same
version number:

$ sudo apt install gnome-software-plugin-flatpak
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 gnome-software-plugin-flatpak : Depends: gnome-software (=
3.30.6-5progress5u1) but 3.30.6-5+progress5u1 is to be installed
E: Unable to correct problems, you have held broken packages.

Does this mean that my apt pinning is still not correctly configured?
How can I verify / rectify? Really sorry about this.

Cheers
Stan
