[Bug 919216] [NEW] aptitude returns 0 exit status code even if the requested action is not successful

[Thomas Nygreen]

Public bug reported:

I have experienced two cases where aptitude returns a 0 exit status
code, even if it prints error messages to the terminal.


Case 1: A package cannot be installed due to unmet dependencies.
Example: (installing something that depends on sun-java on a host with the "partner" repository disabled)

    > sudo /usr/bin/aptitude -y install hadoop-0.20

    The following packages are BROKEN:
      hadoop-0.20
    The following NEW packages will be installed:
      hadoop-0.20-native{a} liblzo2-2{a}
    0 packages upgraded, 3 newly installed, 0 to remove and 0 not upgraded.
    Need to get 41.2MB of archives. After unpacking 92.3MB will be used.
    The following packages have unmet dependencies:
      hadoop-0.20: Depends: sun-java6-jre which is a virtual package.
                   Depends: sun-java6-bin which is a virtual package.
    The following actions will resolve these dependencies:
   
    Keep the following packages at their current version:
    hadoop-0.20 [Not Installed]
    hadoop-0.20-native [Not Installed]

    > echo $?
