[Bug 1285791] Re: Installing default-jdk, uninstalling it, doing apt-get autoremove, and reinstalling it leaves you without /usr/bin/javac ?

[Dan Kegel]

Correction: apt-get purge openjdk-6-jdk *after* uninstalling it does not work around it (it refuses to purge
because the package isn't installed).  
The correct workaround if you know the package is uninstalled is sudo dpkg --purge openjdk-6-jdk.

The problem is present if the package is not installed but is
configured, e.g. if you see:

$ dpkg-query -l openjdk-6-jdk
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Cfg-files/Unpacked/Failed-cfg/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name                      Version                   Description
+++-=========================-=========================-==================================================================
rc  openjdk-6-jdk             6b27-1.12.6-1ubuntu0.10.0 OpenJDK Development Kit (JDK)


instead of

$ dpkg-query -l openjdk-6-jdk
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Cfg-files/Unpacked/Failed-cfg/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name                      Version                   Description
+++-=========================-=========================-==================================================================
un  openjdk-6-jdk             <none>                    (no description available)

Title:
  Installing default-jdk, uninstalling it, doing apt-get autoremove, and
  reinstalling it leaves you without /usr/bin/javac ?

Status in “java-common” package in Ubuntu:
  New

Bug description:
  To reproduce:

  $ sudo lxc-create -t ubuntu -n testbot01-ubu1004-test -- -r lucid
  $ sudo lxc-start -n testbot01-ubu1004-test
  (log in)
  $ sudo apt-get install default-jdk
  $ which javac
  /usr/bin/javac
  $ sudo apt-get remove default-jdk
  $ which javac
  /usr/bin/javac
  $ sudo apt-get autoremove -y
  $ which javac
  $ sudo apt-get install default-jdk
  $ which javac
  $ update-java-alternatives -l
  java-1.6.0-openjdk 1061 /usr/lib/jvm/java-1.6.0-openjdk
  $ sudo update-java-alternatives -a 
  update-alternatives: error: no alternatives for appletviewer.
  update-alternatives: error: no alternatives for extcheck.
  ...
  $ apt-cache policy default-jdk
  default-jdk:
    Installed: 1.6-34
    Candidate: 1.6-34
    Version table:
   *** 1.6-34 0
          500 http://archive.ubuntu.com/ubuntu/ lucid/main Packages
          100 /var/lib/dpkg/status

  If you save a log on the two 'apt-get install default-jdk' lines,
  diffing the two shows:

   Setting up openjdk-6-jre-headless (6b27-1.12.6-1ubuntu0.10.04.4) ...
  -update-alternatives: using /usr/lib/jvm/java-6-openjdk/jre/bin/java to provide /usr/bin/java (java) in auto mode.
  ...
   Setting up openjdk-6-jdk (6b27-1.12.6-1ubuntu0.10.04.4) ...
  -update-alternatives: using /usr/lib/jvm/java-6-openjdk/bin/appletviewer to provide /usr/bin/appletviewer (appletviewer) in auto mode.

  So evidently there's some sort of postinst / postrm problem that only
  shows up on the second install?
