It looks like there are packages without a section field which is declared as "required" by pulp_deb.

Debian only recommends (but does not require) this field (for both source and binary packages): https://www.debian.org/doc/debian-policy/ch-controlfields.html

If follows the plugin should not require it either.

We may want to take this opportunity to check for other falsely required fields.
