How to make snaps see the real /tmp?

  • 772

I'm again and again getting annoyed by the fact that snaps don't see the "real" /tmp.

One example why this is bad is that I'm unable to use "Open with -> Xournalpp" with PDFs from email attachments in Thunderbird because they are stored in the real /tmp for this.

Is there any way (however hacky it may be) to change this so that every snap can access /tmp?

tmp snap restricted-access

  1. If a snap is called mysnap, then by default (with strict confinement) it has a private /tmp, which is /tmp/snap.mysnap/. Having a private /tmp is good for security.

    If you are creating a snap package, you can apply either the classic or devmode confinement, and it will be able to see the system-wide /tmp.
