Package: src:uncertainties Version: 2.4.4-1 Severity: serious Dear maintainer:
I tried to build this package in stretch with "dpkg-buildpackage -A"
(which is what the "Arch: all" autobuilder would do to build it)
but it failed:
--------------------------------------------------------------------------------

This happens randomly. Sometimes it fails. Sometimes it does not.
But it's easy to trigger if the build is attempted enough times.
I attach two build logs in which this test failed.
Thanks.
