Status of qwt-qt6 package needed for QGIS with Qt6

[Julien Cabieces]

Hi everyone,

Qwt with Qt6 dependencies is needed by QGIS to build with Qt 6 support
but is yet missing in current Debian distribution.

I don't have a good understanding of the Debian packaging
process so I fail to understand the current status of qwt packaging in
Debian reading the Debian tracker page [0].

If I understand correctly, current version of Qwt package libqwt-qt5-6
is 6.1.4-2 in stable, testing, and unstable. This package relies on Qt 5
dependencies.

There is a 6.3.0-1 version which has moved into experimental recently
(2025-03-30) and which relies, it seems [1], on Qt 6 dependencies.

Is it a good news and does that mean that qwt-qt6 would land in unstable
soon? If yes, would it land on trixie too ? When ?

If the package is still blocked or not ready to be pushed in any
distribution, what is actually missing and how can we make the
situation move forward?

Sorry if this is not the right place for my question.

Regards,
Julien
