I'm sorry you feel this way. I used the Policy-based severity
definitions to come up with 'serious', as I described earlier in the

The bugs did not evade notice. Piuparts has been tracking this issue
for some time, as a non-failing 'issue'. Affected packages were not
failed only because the very high reverse dependency count of many of
them would have made 90+% of the distribution untestable. The rdep
count has been driven low enough recently that elevating this test has
become viable. The bug filings are a first step in that process.

I wasn't aware of the history of the lintian check.

That's pretty much the point (and a question of semantics).

Take one of the reports for libsamba-util-dev:

    -> libtevent-util.so.0.0.1

# grep libtevent-util samba4-4.0.0~beta2+dfsg1/debian/*

... and libsamba-util-dev does not depend on libsamba-util0.

dpkg --contents shows that libsamba-util-dev installs two .so symlinks
that do not resolve to a valid targets.

So, I claim that libsamba-util-dev is purporting to provide two shared
libraries without following through on the contract. That is what I am
calling a serious bug, as defined by Policy.

It looks like the simple fix here is to add a Depends on libsamba-util0.

Again, I am sorry for the confusion. I felt I had achieved consensus,
as evidenced by a quieting of the thread, and no attempts at rebutting
the Policy justification.

I guess the next step is a clearer statement of consensus on what to do next.

My position - I believe that the bug submittal, and the current
severity, is appropriate.

I will make changes should consensus dictate. (I may need some help
determining what constitutes consensus).
