Hello @memchr, Steam should be calling xdg-desktop-portal to open a user-selected file dialog box, but the Arch packaging does not currently require the relevant dependency to be installed with Steam. This is a distro packaging issue being tracked at https://bugs.archlinux.org/task/78625. You're reaching this dialog window because xdg-desktop-portal failed for some reason.
Install the xdg-desktop-portal system package and the corresponding backend of your choice. (https://wiki.archlinux.org/title/XDG_Desktop_Portal)
Hi @kisak-valve, I have xdg-desktop-portal installed on my system, but it seems that the xdg-desktop-portal-wlr implementation does not support the file chooser. I will close this issue, thank you for your time.
I have this problem on fedora 38, gnome 44.4. xdg-desktop-portal is installed and so is xdg-desktop-portal-gnome for my environment of GNOME, but I magically lost my existing library location after restarting steam. It was in /media/steam I can no longer add my existing library back and receive #ContentManagement_Error_ I too get an empty dialog.
I see steam attempt to write to " /media/.steam_exec_test.sh" but it should be attempting to write to
"Couldn't write /media/steam/.steam_exec_test.sh" No clue why my locations were magically removed.
Changing perms against my wishes on /media, steam could then recreate the very restrictive path (unchoosable by me) in /media/SteamLibrary which is totally useless. I was able to get my install to work again (and get back my lost progress), by fapping around and letting steam install in /media/SteamLibrary then moving all my crap from /media/steam. I've had to loosen my perms on /media. This sucks. This all occurred after a large outage today. I don't feel like xdg-desktop-portal is broken, because I can "browse files" from steam. Posting to a closed ticket because I really found nothing else on the internet similar to my issue.
Nothing extracted yet.
