Public bug reported:

The man page for apt-get states:

       -m, --ignore-missing, --fix-missing
           Ignore missing packages; if packages cannot be retrieved or fail the integrity check after retrieval (corrupted package files), hold back those packages and handle the
           result. Use of this option together with -f may produce an error in some situations. If a package is selected for installation (particularly if it is mentioned on the
           command line) and it could not be downloaded then it will be silently held back. Configuration Item: APT::Get::Fix-Missing.

However, when removing or purging packages, it does /not/ actually
ignore missing packages:

build@ub14test:~/p4/zimbra/main/ThirdParty/openldap$ sudo apt-get purge -y --ignore-missing zimbra-openssl-lib
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package zimbra-openssl-lib
build@ub14test:~/p4/zimbra/main/ThirdParty/openldap$ echo $?
100

This causes some pain when using apt-get in a Makefile and wanting to
ensure custom packages have been removed.

dpkg handles this correctly:

build@ub14test:~/p4/zimbra/main/ThirdParty/openldap$ sudo dpkg --purge zimbra-openssl-lib
dpkg: warning: ignoring request to remove zimbra-openssl-lib which isn't installed
build@ub14test:~/p4/zimbra/main/ThirdParty/openldap$ echo $?
0

however you then lose dependency tracking.
