I'm running Pop!_OS 22.04 LTS (a flavor of Ubuntu), all updates available in the Pop Shop have been installed. Apps installed via flatpak appear to have a permissions issue.

For example--

  • Brave: can't import bookmarks
  • Calibre: Add books > select file gets message "calibre, version 6.9.0 ERROR: Cannot add books: You do not have permission to read any of the selected files."
  • Newsflash: Can't import file containing feeds, freezes when trying to import file
  • Element: Can't attach files
  • Zoom: Can't attach files in chat
  • KeePassXC: Can't add attachments, freezes when tried
  • Signal: Can't upload or download attachments, crashes after asking where to save the file.

I've installed Flatseal, but changing its settings has not helped (possibly because it too is a flatpak app). I also reinstalled flatpak. Running the apps from terminal doesn't help. Rebooting has not helped, nor has repairing flatpak.

Any suggestions would be much appreciated. Thank you!

  • What happens if you launch a Flatpak app from the CLI passing the --filesystem=home flag? E.g. flatpak run com.brave.Browser --filesystem=home.

  • Thanks. Same problem. I tried Signal so flatpak run org.signal.Signal --filesystem=home . Pressed the down arrow next to a photo to save it, was prompted to pick a location and then the app crashed. Commented Dec 2, 2022 at 12:50
  • Did you get any messages in the console?

  • Yep! Just put it on pastebin (please LMK if there's a better way to share messages or code that are longer than what we can post in the comments). Thanks! pastebin.com/f7DN06W4 Commented Dec 2, 2022 at 15:42
  • Re Calibre error. There is a section in the documentation faq that may be helpful: manual.calibre-ebook.com/… I am not sure it is wise to assume these are related problems and related to a system wide permissions problem. (Which seems unlikely in a fresh Pop install unless there were problems during installation.) I assume you have made sure your system is up to date by running sudo apt update followed by sudo apt upgrade (if you find anything to upgrade).

You should grab the Flatseal app from the Pop Shop. It will allow you to enable all of the Flatpak permission with a GUI.


Fixed the problem by deleting and re-installing all the Flatpak apps.
