[Pkg-dns-devel] Bug#884175: typo in pdns-backend-mysql sometimes breaks upgrades

[johan A. van Zanten]

Package: pdns-backend-mysql
Version: 4.0.5-1pdns.jessie
Severity: normal

This appears to be a duplicate of #816362 , which was an older version of
the package, 4.0.0_alpha2-2 .

This typo seems to sporadically cause problems when upgrading from an
older version of the package:

Setting up pdns-backend-mysql (4.0.5-1pdns.jessie) ...
