Why can't I read PNG or SVG?

I just installed Natron for the first time and am trying to check it out. However, I can’t seem to read in files. I’ve tried both PNGs and SVGs. Here’s an example error message:

Error while creating node fr.inria.built-in.Read: Could not find a decoder to read png file format.

Natron 2.3.14 on Ubuntu 19.10, installed via snap

Hi,

We do not maintain the snap package. Since it’s a sandbox you could be missing some permissions, this is not the first issue report regarding this snap package and file permissions.

I recommend getting binaries from Releases · NatronGitHub/Natron · GitHub

That there’s the challenge. Of course, I know that few upstreams maintain packaging. Yet I’ve learned years ago that it’s a mistake to install software outside of the normal package sources unless it’s software I’m actively developing. So I’m a bit stuck here.

Your reply does seem to indicate that PNG and SVG are supposed to work, so I’ll file a bug against the snap package.

We have portable and self-contained binaries for Linux, no installation required.
