Tag: invalid-arch-string-in-source-relation Severity: error Check: fields/package-relations See-Also: debian-policy 5.6.8 Explanation: 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].
