[Bug 1354602] Re: package rpcbind 0.2.0-7ubuntu1.2 failed to install/upgrade: trying to overwrite '/usr/share/man/man8/rpcinfo.8.gz', which is also in package libc-bin 2.15-0ubuntu10.6

[Steve Langasek]

** Description changed:

  [Impact]
  A missing replaces: from rpcbind against the version of libc-bin in 12.04 means that upgrades may fail if libc-bin and rpcbind aren't unpacked in the "right" order.
  
  [Test case]
- 1. Install rpcbind on 12.04.
- 2. dist-upgrade to 14.04.
+ 1. On 12.04, apt-get install rpcbind
+ 2. Update /etc/apt/sources.list to point to trusty.
+ 2. apt-get install rpcbind
  3. confirm that the upgrade fails due to rpcbind being unpacked before libc-bin is upgraded.
  4. enable trusty-proposed in sources.list.
- 5. apt-get -f install
  6. apt-get install rpcbind
  7. confirm that the package install completes successfully
  8. confirm that apt-get dist-upgrade completes successfully
  
  [Regression potential]
  Any changes to the package relationships may have an unforeseen detrimental impact on apt's resolver.  However, these are non-trivial to find in advance and this change is locally correct with regards to package relationships.

  Received an upgrade notice. I executed the upgrade procedures which
  indicated 529 packages need to be installed. Upgrade requesrted that I
  install the DVD. of the ISO file I had downloaded. Upgrade did not
  complete and failed to reboot. I had to use "recovery mode" in order to
  log back in. Again I received a mesage indicvating that 244 files needed
  to be upgrade. This attempt alos failed. Received various messages the
  there were dependencies issue and could not continue the upgrade
