[backintime] Advise about unresponsive DPM and new 1.5.6 release

Hello again,
and sorry to bother all of you with this issue.

I am upstream maintainer of backintime [1]. My DPM (Jonathan Wiltshire, 
jmw) is unresponsive and does not react (for 3 months now) to my last 
hotfix release [2] and also not to emails. The other two "uploader" 
expressed to me that they won't be able to do more maintenance tasks on 
that package.

I don't know what to do. Not having an upload of this release would be 
fine for me, but only if I have a reasons. To give a reason some 
communication need to be done. And that is what jmw is missing.

I have this problem since I took over the upstream project in 2022. MIA 
is not an option because jmw manages to "react" (with upload but no 
answers) in a time span less then 6 months. The Debian Python Team also 
refuse to take over the package without jmw giving it away. The 
situation is frustrating because I do not know the reasons and there is 
no communication.

Any advice?

Best regards,
Christian Buhtz
