Package: devscripts
Version: 2.17.12ubuntu1
Followup-For: Bug #840943
Dear maintainer team,
I encountered the following bug when I using uscan with
pgpmode=next/previous. I also came across this bug which seems to
be fixed in the devscripts version I'm running, but I stumbled into
antoher, may related, error. So I did not open a new one.
My debian/watch file contains the following:
version=4
opts="pgpmode=next" \
https://0xacab.org/riseuplabs/trees/wikis/home \
(?:.*/)trees-@ANY_VERSION@\.tar\.gz
opts="pgpmode=previous" \
https://0xacab.org/riseuplabs/trees/wikis/home \
(?:.*/)trees-@ANY_VERSION@@SIGNATURE_EXT@ \
previous
If my changelog contains the same version as the upstream version uscan
works correct and I run uscan via: uscan --verbose --report --download
I get the info my package is uptodate, but obtaining the signature
"fails". I get the warning: "Use of uninitialized value $lastversion in
concatenation (.) or string at /usr/bin/uscan line 2749, <WATCH> line
12." I would expect that uscan should also fetch the signature or skipping
that step, but the warning is quite confusing.

I'm not sure if that behaviour is intended. Thank you!
