Getting "'file' is different from the same file on the system" when I attempt to update through synaptic

Encountered an error while updating through Synaptic Manager. Subsequent updates gave the error at the bottom of the output. I'm a noob so any help is appreciated.

Specific answer

Try these commands in a terminal:

sudo dpkg -r libjack-jackd2-0

sudo apt-get -f install

sudo apt-get update

sudo apt-get upgrade

The commands remove the offending file, attempts to fix the broken dependency and updates your system.

General answer

Errors were encountered while processing:

/var/cache/apt/archives/libjack-jackd2-0_1.9.8~dfsg.2-1precise1_i386.deb

E: Sub-process /usr/bin/dpkg returned an error code (1)

If you are getting an E: Sub-process /usr/bin/dpkg returned an error code (1) (Should be error code (1)), you can attempt to fix this with the following things in mind:

Take note of the package name after /var/cache/apt/archives/. In this case, the filename is libjack-jackd2-0_1.9.8~dfsg.2-1precise1_i386.deb, so the package name is libjack-jackd2-0 (take the filename up until the first '_', generally). With these in mind, just run the following commands:
```
sudo dpkg -r libjack-jackd2-0

sudo apt-get -f install

sudo apt-get update

sudo apt-get upgrade
```
