Bug#776477: tomcat7: fails to switch from tomcat6 to tomcat7 on upgrades

Wed Jan 28 13:17:42 UTC 2015

Package: tomcat7
Version: 7.0.56-1
Severity: serious
Tags: patch
User: debian-qa at lists.debian.org
Usertags: piuparts
Control: affects -1 + solr-tomcat

Hi,

during a test with piuparts I noticed your package fails to upgrade from
'wheezy'.
It installed fine in 'wheezy', then the upgrade to 'jessie' fails.

Even after the upgrade it is not possible to install solr-tomcat again
(without removing tomcat6 manually).

>From the attached log (scroll to the bottom...):

[ wheezy# apt-get distupgrade ]

  The following packages will be REMOVED:
    solr-tomcat

Removing the package to be tested is not optimal, but sometimes
unavoidable. So let's reinstall afterwards.

[ jessie# apt-get install solr-tomcat ]

  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:
   solr-tomcat : Depends: tomcat7 but it is not going to be installed
  E: Unable to correct problems, you have held broken packages.

The attached patch adds

  Package: libtomcat7-java
  Conflicts: tomcat6, tomcat6-common

This at least fixes the installation of solr-tomcat in jessie since this will
ensure the removal of tomcat6. It does not prevent to (temporary) removal
of solr-tomcat during the distupgrade to jessie. That would require
  Breaks: tomcat6, tomcat6-common, libtomcat6-java
in a (possibly unrelated) package with sufficiently high score.

The upgrade situation might clear up if the tomcat6, tomcat6-common binary
packages get removed from jessie (src:tomcat6 in sid only build some java
libraries, but no longer tomcat6 etc).
But as long as tomcat6 is installed and a valid install candidate, apt-get
gives "install tomcat7 instead" a too low score.

cheers,

Andreas
