Same here. > It stopped working after I switched the media qube's template from > debian-11-minimal to debian-12-minimal. I am not sure if that per se is the reason. It used to work for me in debian-12-minimal too. Here is what I get when I "Open in VM" a text file (VM is based on debian-12-minimal with thunar, xpdf and mpv installed).

Tested with an mp4 file - same result. I can open the files through thunar, where I can set default app for the type too. However, thunar does not use xdg-open but exo-open. Next, I looked at the code of xdg-open (it is a shell script) and I saw it used some form of desktop environment (DE) detection and acted based on that. So, to see what exactly happens: $ bash -x xdg-open TEST.pdf ... + DEBUG 2 'Selected DE gnome3' ... + open_gnome3 TEST.pdf + gio help open + gvfs-open --help + open_generic TEST.pdf ... And there it is: xdg-open wrongly detects gnome3 which is not installed. Then I checked: $ printenv | grep XDG_CURRENT_DESKTOP XDG_CURRENT_DESKTOP=X-QUBES ## NOT XFCE, which is the correct value After: $ export XDG_CURRENT_DESKTOP=XFCE xdg-open works as expected in the current session. To have "Open in VM" work as well, obviously the above must be set persistently. Speculation 1 (needs checking and confirmation): Since I see in a fedora-xfce-template-based qubes the XDG_CURRENT_DESKTOP=XFCE, I suppose it is somehow set when XFCE itself is installed (and not just thunar), so perhaps the fact of the Debian template being "-minimal" (and not "-xfce") is related to this issue and one needs to set this thing manually to make it work properly. Speculation 2 (if the above is wrong): It might be Debian specific.
