Re: unable to run photoqt
Run it from a terminal emulator and post the output?

Re: unable to run photoqt
it functions on devuan 7 with kde, it seems a handy app.
on devuan 6 with mate, there is probably missing some functionality?
it would open up, but there is not possible to open files - the screen would not respond to mouse commands.
like errors

Re: unable to run photoqt
Ok, here is what I got in cli when trying to run photoqt
shows missing module: PQMainWindow.qml::::24: qrc:/src/qml/PQMainWindow.qml:24:1: module "QtQuick.Window" is not installed
so, I installed: qml6-module-qtquick-window/stable 6.8.2+dfsg-7 amd64
rerun photoqt:
shows missing module: PQToolTip.qml::::24: qrc:/src/qml/elements/PQToolTip.qml:24:1: module "QtQuick.Controls" is not installed
so I installed:
qml6-module-qtquick-controls/stable 6.8.2+dfsg-7 amd64
Qt 6 Quick Controls QML module
now shows missing module: PQMultiEffect.qml::::23: qrc:/src/qml/elements/PQMultiEffect.qml:23:1: module "QtQuick.Effects" is not installed
so I installed:
qml6-module-qtquick-effects/stable 6.8.2+dfsg-7 amd64
Qt 6 Quick Effects QML module
************************************
now it appears to work.

Re: unable to run photoqt
I don't see those 3 modules in the dependencies for this package:
https://pkginfo.devuan.org/cgi-bin/pack … 4.8.1+ds-1
So, package is not configured correctly? missing dependencies.

Re: unable to run photoqt
thanks.
I checked photoqt in debian packages. Those 3 are not present in the list. since devuan is a mirror at heart, I suppose the issue exists in Debian stable and needs to be fixed there? In such a case, would devuan admins be opening a bug with debian admins?

Re: unable to run photoqt
it may very well be that the version of "testing" is still exhibiting the behaviour;
i am not sure what software version the laptop has since it is getting always updates, so it must be mix propablyzy
of devuan 7 and or/sid.
photoqt --version
PhotoQt 5.3

this aligns with "next-testing" and "testing" from the reportbug-window in gui-mode.
have included reference to the 3 packages, but the rest is up to the responsible persones.
if the program is included int the repos, it should be able to run - no questions asked - that is maybe universally agreeable.
thank you again for letting know of the program and proposing a "fix".
