Lintian tag information: invalid-arch-string-in-source-relation (type: error)

Description (from lintian-explain-tags)

The architecture string in the source relation includes an unknown
architecture. This may be a typo, or it may be an architecture that dpkg
doesn't know about yet. A common problem is incorrectly separating
architectures with a comma, such as [i386, m68k]. Architectures are
separated by spaces; this should instead be [i386 m68k].

Please refer to Architecture (Section 5.6.8) in the Debian Policy Manual
for details.
