I reviewed the branch where you put the backport patch and it seems mostly good to me. The only comment I have is about the version string you chose:
1.6.9-2~bpo10+1~bpo20.04.1
I understand that this is probably because you based your work on top of the backport for buster, but I don't like the double-tilde in the version. Could you please change it to a single tilde and remove the "~bpo10+1" part?
Thanks for the bug report, Fabio.

Apart from that, the rest LGTM.
