Bug#217862: dpkg doesn't check if package upgrade breaks versioned dependences

["Nikita V. Youshchenko" <yoush@cs.msu.su>]

Package: dpkg
Version: 1.10.15
Severity: important

This bug may be easilly reproduced.
Create dummy package p1, version 1, and dummy package p2, version 1,
that Depends: p1 (= 1).
Install both.
Now create package p2, version 2, and try to install it with dpkg -i,
without any --force.
Dpkg will silently do it, breaking the dependency for package p2.

This does cause system breakages if packages are installed without apt
(which is useful sometimes).
E.g. if libfoo-dev does need exact version of libfoo ...
