I’m trying to install Signal via Flatpak from Flathub, but it fails with a generic permission denied error and no other details. Does anybody have any ideas on how to solve this problem or even debug it? Thanks in advance for any ideas / suggestions.

I upgraded Flatpak from 1.2.5 to 1.8.2 to avoid a umask issue fixed in 1.3.3, but that did not appear to help. I also ran restorecon -Rv ~/.local, but that did not appear to help either.
Possibly relevant details:
