Bug#763382: mk-origtargz: "Use of uninitialized value $mime" and failure to handle upstream jam-2.6.tar

[Yann Dirson]

Package: devscripts
Version: 2.14.6
Severity: normal

While updating watch file for new upstream URL for jam:

jam-2.5rel$ uscan --verb

The downloaded stuff is indeed an HTML page (ie. the "does not look
like a tar archive" part of the diagnostic) is correct, though.


But if I download the real tar manually[1], and launch mk-origtargz
manually, I still get the uninitialized warning and a "does not look
like a tar archive" error, which this time is wrong:

jam-2.5rel$ mk-origtargz --package jam --version 2.6 --compression gzip --directory .. --copyright-file debian/copyright ../jam-2.6.tar
