I've tried installing it about a dozen times over the past year, but it always gives an "unable to get image" error. So I'm wondering if there's an alternative that does everything paperless does...but lets me use it
Papermerge version 2.0, version 2.1 and version 3.0 are entirely different and incompatible applications.
That doesn't exactly inspire confidence in the future versions of this application, given in particular the use case of long-term document archival :).
