Package: apt Version: 1.0.9.4 Severity: important Hi,
the following bug is a major burden when working with Debian repositories that contain multiple versions of one package. Image following example: You have two packages named A and B. A in version 1 depends on B in version 1. Apt will automatically install B=1 when you install A=1. Now assume you have A available in version 1 and 2 and B in version 1 and 2. If A and B are currently not installed, apt will try to install B=2 when you want to install A=1. This fails of cause because of the package dependencies. This is probably a bug in apt as it sees version 2 for B as the best install candidate even if the dependency says different. Steps to reproduce: =============================================================================== #!/bin/sh set -e mkdir /tmp/alpha-1.0 && cd /tmp/alpha-1.0 dh_make -c mit -s -n -p alpha_1.0 -y sed -i 's/^Depends: /Depends: beta (= ${binary:Version})/' debian/control debuild -b dch -v 2.0 'Bump version' cd ../alpha-2.0 debuild -b mkdir /tmp/beta-1.0 && cd /tmp/beta-1.0 dh_make -c mit -s -n -p beta_1.0 -y debuild -b dch -v 2.0 'Bump version' cd ../beta-2.0 debuild -b cd /tmp apt-ftparchive packages . | gzip > Packages.gz echo "deb file:///tmp/ ./" >> /etc/apt/sources.list apt-get update apt-get install alpha=1.0 =============================================================================== Apt throws following error message instead of installing alpha=1.0 and beta=1.0: Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: alpha : Depends: beta (= 1.0) but 2.0 is to be installed E: Unable to correct problems, you have held broken packages. -- Benjamin Drung System Developer ProfitBricks GmbH - The IaaS-Company Greifswalder Str. 207 D - 10405 Berlin Mail: benjamin.dr...@profitbricks.com Fax: +49 30 577 008 598 URL: http://www.profitbricks.com Sitz der Gesellschaft: Berlin.
