I am trying to install driver for my printer but this happened..

 $ sudo dpkg -i openprinting-gutenprint_5.2.7-1lsb3.2_amd64.deb 

    (Reading database ... 204753 files and directories currently installed.)

    Unpacking openprinting-gutenprint (5.2.7-1lsb3.2) ...

    dpkg: dependency problems prevent configuration of openprinting-gutenprint:

     openprinting-gutenprint depends on lsb (>= 3.2); however:

      Package lsb is not installed.



dpkg: error processing package openprinting-gutenprint (--install):

 dependency problems - leaving unconfigured

Errors were encountered while processing:

 openprinting-gutenprint

After that I tried installing lsb..

$ sudo apt-get install lsb

Reading package lists... Done

Reading state information... Done

You might want to run 'apt --fix-broken install' to correct these.

The following packages have unmet dependencies:

 lsb : Depends: lsb-core (>= 9.20170808ubuntu1)

       Depends: lsb-printing (>= 9.20170808ubuntu1) but it is not going to be installed

       Depends: libjpeg62 but it is not going to be installed

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

Finally I tried installing lsb-core, but..

$ sudo apt --fix-broken install

dpkg: error processing package install-info (--configure):

Errors were encountered while processing:

 install-info

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

The following are in my /etc/environment file:

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"

JAVA_HOME="/usr/lib/jvm/java-11-openjdk-amd64/bin/"

As sugested in a thread linked in the comments above, run:

sudo mv /var/lib/dpkg/info/install-info.postinst /var/lib/dpkg/info/install-info.postinst.bad

If it doesn't solve your problem, revert it by

sudo mv /var/lib/dpkg/info/install-info.postinst.bad /var/lib/dpkg/info/install-info.postinst

Just ran

sudo apt --fix-broken install

and worked
