    Did you replace /usr/bin/dpkg with a shell script or something? What is the output of file /usr/bin/dpkg? What commands did you run involving dpkg before this?

  • That error can happen if /usr/bin/dpkg is the wrong binary architecture for your system (such as ARM on x86, or possibly x86_64 on i386)

Okay 32-bit. 

mkdir $HOME/dpkg

enter this directory

cd $HOME/dpkg

then download dpkg with wget.

wget -c http://mirrors.kernel.org/ubuntu/pool/main/d/dpkg/dpkg_1.19.0.5ubuntu2_i386.deb

uncompress the deb package.

ar x dpkg_1.19.0.5ubuntu2_i386.deb

then we extract the datas.

tar xf data.tar.xz

then substitute the wrong dpkg.

sudo cp ./usr/bin/dpkg /usr/bin/dpkg

then try

sudo apt-get clean && sudo dpkg --configure -a

when dpkg is working again.

dpkg --print-foreign-architectures

If you get an output,

remove foreign-architectures

but you have to adapt it to your situation. you have to change the part i386 to the one you get from output. I hope the last part is understandable.

If you are unsure show the output from last command.
