Hi,

the last maintainer upload of ddd was in 2013. Since then upstream
released new versions, and 4 NMUs happened in Debian.
As far as I can tell the currently listed maintainer has no signing
key recorded since 2015.

I thus intend to orphan this package, no earlier than 2025-09-15.

If someone wants to continue maintaining this package before that
date, please just step in and close this bug.

Chris
