Package: qgis Version: 3.44.8+dfsg-1 The QGIS package in Debian seems to have no AppStream metadata generated for some reason:
https://appstream.debian.org/sid/main/metainfo/qgis.html https://appstream.debian.org/sid/main/issues/qgis.html Because of this, it is not possible to search this app and install it using a graphical software store such as GNOME Software or KDE Discover.
