Hi Hadmut,

Did you by any chance enable an additional repository or PPA from which you're installing aeskulap?

Ubuntu 11.04 includes aeskulap 0.2.2b1-7ubuntu1 and dcmtk 3.6.0-1ubuntu1, which should install well together.

I notice the version of aeskulap you're trying to install is Package: aeskulap 0.2.2b1-6 (notice, no ubuntu in the version number meaning that it's not an official Ubuntu package), and it depends on dcmtk >= 3.6.0-2 (but on Ubuntu, the version of dcmtk is the one I mentioned earlier).

Please verify whether you have an additional software source or repository from which these packages might have come. One thing you might try is disabling those additional sources, then running, from a terminal:

sudo apt-get update

and then trying to install the version of aeskulap from Ubuntu 11.04.

Please report back with your results, so we can determine whether this is indeed a bug in Ubuntu or possibly just a package mismatch issue.

Thanks!

I have a few additional repositories, but none of them is related to aeskulap. I installed aeskulap more than two or three years ago and just let it run through the normal ubuntu updates.

But I think we are talking about different packages. My dpkg says

Package: aeskulap
Architecture: amd64
Version: 0.2.2b1-7ubuntu1
Depends: ... dcmtk (>= 3.6.0-2) ...

And if I have a look at

http://packages.ubuntu.com/natty/aeskulap

it also says that aeskulap 0.2.2b1-7ubuntu1 of the official repository depends on dcmtk (>= 3.6.0-2)

A already tried the update + install several times. Same error message (that's what I took the message in the bug report from)

If it depends on dcmtk (>= 3.6.0-2) it obviously cannot install with 3.6.0-1ubuntu1

Hi Hadmut,

Thanks for replying.

Apologies, I got confused with the mismatching versions between libdcmtk and dcmtk proper.

You're correct that aeskulap for 11.04 depends on a version of dcmtk which is not present/installable in the repository. On a freshly installed Natty system, apt-get install aeskulap gives the same error you're receiving.

I verified this on two Natty systems, and I even found a prior bug; thus, I'm setting this report to a duplicate of bug 777940. As a subscriber to this report, you will get notifications when the other one gets updated.

Hadmut, a possible workaround to successfully upgrade your system would be to remove aeskulap prior to attempting the upgrade. However, until bug 777940 is resolved, you will not be able to reinstall aeskulap :( I apologize for this inconvenience and expect the other bug to be solved soon.

Thanks again!
