AssertionError: False is not true : 
The following packages failed upstream version checks. Please fix them using UPSTREAM_CHECK_URI/UPSTREAM_CHECK_REGEX
(when using tarballs) or UPSTREAM_CHECK_GITTAGREGEX (when using git). If an upstream version check cannot be performed
(for example, if upstream does not use git tags), you can set UPSTREAM_VERSION_UNKNOWN to '1' in the recipe to acknowledge
that the check cannot be performed.

The following packages have been checked successfully for upstream versions,
but their recipes claim otherwise by setting UPSTREAM_VERSION_UNKNOWN. Please remove that line from the recipes.
