[Bug 951493] Re: package libsensors4 1:3.3.1-2ubuntu1 failed to install/upgrade: conffile './etc/sensors.d/.placeholder' is not in sync with other instances of the same package

[Sachin]

I also have this issue  after upgrading from i386 to amd64 12.04.

$sudo apt-get upgrade

You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
 libsensors4-dev:i386 : Depends: libsensors4:i386 (= 1:3.3.1-2ubuntu1) but it is not installed
E: Unmet dependencies. Try using -f.

add the -f option and it tries to install:

[...]Unpacking libsensors4:i386 (from .../libsensors4_1%3a3.3.1-2ubuntu1_i386.deb) ...
dpkg: error processing /var/cache/apt/archives/libsensors4_1%3a3.3.1-2ubuntu1_i386.deb (--unpack):
