[Bug 1315119] Re: package trousers 0.3.11.2-1 failed to install/upgrade

[Rich Evans]

I can see the issue on Ubuntu 14.04.  This is being cause by incorrect
udev rules for the /dev/tpm0 node.  Trousers init should change
ownership to tss:tss of /dev/tpm0 but is failing to do so.  Worked
around by:

Attempt to install trousers and it fails:
sudo apt-get install trousers
Reading package lists... Done
Building dependency tree       
Reading state information... Done
trousers is already the newest version.
0 to upgrade, 0 to newly install, 0 to remove and 0 not to upgrade.
1 not fully installed or removed.
After this operation, 0 B of additional disk space will be used.

dpkg: error processing package trousers (--configure):

Manually take ownership of /dev/tpm0:
sudo chown tss /dev/tpm0
sudo chgrp tss /dev/tpm0

Force reinstallation of trousers and it succeeds:
sudo apt-get install -f trousers
