fuse device missing

[fowr0yl]

I just updated my Manjaro LXC Container. But now flatpak inside this container did not work anymore.
I guess because this error found with journalctl:

Jan 12 12:45:18 ManjaroLxQT org.freedesktop.portal.Documents[8178]: fuse: device not found, try 'modprobe fuse' first
Jan 12 12:45:18 ManjaroLxQT org.freedesktop.portal.Documents[8178]: error: fuse init failed: Can't mount path /run/user/500/doc

Trying to "modprobe fuse" gives me another error.

[root@ManjaroLxQT user]# modprobe fuse
modprobe: FATAL: Module fuse not found in directory /lib/modules/5.15.116-1-pve

Seems that flatpak needs fuse to mount internal directories, but fuse is not available.

How to enable fuse ?

Hi,
you will have to enable fuse support for the container by going in the WebUI to <Container> > Options > Features > Edit and check the corresponding FUSE checkbox.

Hi Chris,

thank you for the hint.
But after enabling fuse I ran into the next error

admin@ManjaroLxQT tmp]$ /usr/bin/flatpak run --branch=stable --arch=x86_64 --command=/app/bin/HeiseArchiv --file-forwarding de.heise.app.HeiseArchiv @@u %U @@
