[Bug 873435] Re: package libqwt-dev - failed to upgrade

[David Kalnischkies]

This is caused by dpkg stripping the ending dash from the version number in the Replaces dependency.
Online is:
Replaces: libqwt5-qt4-dev (<< 6.0.0-)
After installation you have in dpkg/status:
Replaces: libqwt5-qt4-dev (<< 6.0.0)

APT therefore detects these two versions as different as they have different dependencies. Having the dash around doesn't make a lot of sense for libqwt-dev, but removing it in the status file isn't the nicest think which could be done by dpkg, too.
Either way, not really a bug in APT…

(qwt has a bugreport in debian for this, too: See http://bugs.debian.org
/cgi-bin/bugreport.cgi?bug=631816)

** Bug watch added: Debian Bug tracker #631816

** Package changed: apt (Ubuntu) => dpkg (Ubuntu)
