SyntaxWarning: "is not" with a literal

[amichair]

In the upgrade to Kubuntu 20.04, I noticed in the apt log this error when setting up usb-creator-kde . After the upgrade I ran apt install --reinstall usb-creator-kde to try again and got the same error:

Preparing to unpack .../usb-creator-kde_0.3.7_amd64.deb ...
Unpacking usb-creator-kde (0.3.7) over (0.3.7) ...

I reverted 0.3.15 back to kinetic-proposed and copied 0.3.13 back to kinetic. usb-creator 0.3.15 is not ready for migrating as it causes component-mismatches right now (2nd level of dependencies).

The usb-creator->libisoburn->jigit & usb-creator->libisofs->jigit dependency got dropped (jigit part) to avoid the component mismatch.
