dpkg: error processing archive

I got this error when trying to install anything on ubuntu 16.04.

SyntaxError: invalid syntax
dpkg: error processing archive /var/cache/apt/archives/python-
samba_2%3a4.3.11+dfsg-0ubuntu0.16.04.6_amd64.deb (--unpack):

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

I have tried apt-get -f install but it shows the same error . could anyone help ?


  • After a while in searching , i have fixed the problem with those lines in terminal:

     $ sudo apt-get clean
     $ sudo apt-get update
     $ sudo apt-get install --reinstall python-minimal python-lockfile
     $ sudo apt-get -f install
