Bug#771971: dpkg hangs installing "init" during upgrade from wheezy to jessie

[bnewbold@robocracy.org]

Hello all,

I also had this problem when upgrading my amd64 laptop from wheezy to 
jessie.

My apt and general system configuration on this machine was not 
particularly hygienic or well documented, so mine might not be a very high 
signal datapoint, however I was ultimately able to complete the upgrade.

I use full disk encryption so my heart initially jumped up my throat when 
I hung on "Selecting previously unselected package init." with 100% CPU
utilization on a single core.

After some ugly desperate kludging, including:

  sudo rm /var/cache/apt/archives/lock

and running `sudo apt-get dist-upgrade` several times (all hanging), I 
eventually simply ran:

  sudo apt-get install init

which succeeded, and was then able to proceed with `sudo apt-get 
dist-upgrade`.

PS, much thanks to all debian developers and maintainers for your hard 
work! I love you!
