[Piuparts-devel] Bug#1088928: piuparts: fails to convert UNRELEASED to unstable for apt

[Soren Stoutner]

Package: piuparts
Version: 1.5.1
Severity: normal

In attempting to run piuparts with the instructions at:

https://wiki.debian.org/sbuild#Setup

I noticed that if the changelog targets UNRELEASED and no distribution is specified
in either .sbuildrc or via the command line, piuparts fails to resolve apt
because it is looking for UNRELEASED instead of unstable.

Both the build and autopkgtest convert UNRELASED to unstable for the purposes of apt.
