Matthew, thank you for properly identifying the responsible component of Ubuntu 18.04 that prevents Thunderbird and VLC from interoperating. "gnome-software" is more precise.
This is not a Thunderbird, VLC or snapd problem. This is an Ubuntu 18.04 application packaging issue. The problem is that Thunderbird saves a temporary attachment file in /tmp before invoking a helper application to open it. If the helper application associated with the file is VLC, VLC does not have permission to open the file. (In fact, the system /tmp directory is not even in the VLC snap's filesystem name space.) The solution is to build and configuration VLC for this Ubuntu release so that it shares its /tmp directory with the system /tmp directory, i.e. they are one and the same. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1897460 Title: VLC Snap Incompatible With Thunderbird To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-software/+bug/1897460/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
