flatpack-info: read-only file system

[ngirard]

Using latest 2.2.0 version from the pre-compiled package on Ubuntu 20.04.
Starting Foliate leads to a blank page with spinning cursor and the following error message:

bwrap: Can't create file at /.flatpak-info: Read-only file system

WebKit sandboxing was enabled in 23b6b03. It seems that it might cause problems in some situations? Googling leads to this bug report: https://bugzilla.redhat.com/show_bug.cgi?id=1781631, but it seems that no one knows why it happens.

As a workaround you can try setting WEBKIT_FORCE_SANDBOX=0 to disable the sandbox (use WEBKIT_FORCE_SANDBOX=0 com.github.johnfactotum.Foliate to launch Foliate).

Good catch John, setting the variable allowed Foliate to work properly.

Would it be possible to propagate this fix to a new package ?

Also congrats for the new library view, it's awesome !

[johnfactotum]

Ideally we'd want to fix the issue rather than disabling the sandbox. But if lots of people are having issues I guess it should be turned off by default.

Hey @johnfactotum,

I'm about to bring an Ubuntu-based laptop to its owner, and I wish to have Foliate 2.2 installed on it.
What would you advice me to do for a temporary fix ?
To add a export WEBKIT_FORCE_SANDBOX=0 to the user bashrc ? Or to add it to the foliate.desktop file ?

To add a export WEBKIT_FORCE_SANDBOX=0 to the user bashrc ?

This will disable sandboxing for all WebKit processes on the system. Don't do that unless you're also having problems with other WebKit apps.

Or to add it to the foliate.desktop file ?

I think that's probably the best workaround for now.

It seems this has been fixed upstream: https://bugs.webkit.org/show_bug.cgi?id=202880
