Dear Maintainer,


Debian stable disables unprivileged user namespaces by default.

QtWebEngine sandbox requires user namespaces, making official
kiwix-desktop unusable out of the box.

The only working workaround: export QTWEBENGINE_DISABLE_SANDBOX=1

Please fix this in Debian packaging: Either set this env var in the
official .desktop file, or add a sandbox patch like chromium.

Debian's chromium-browser has sandbox downgrade patches, but
kiwix-desktop is shipped raw without adaptation, resulting in broken
software for default installations.

The presupposition that user namespaces are disabled by default is false.
So this is certainly not a grave bug.
