Unmet dependencies when trying to install r-base

I have a problem with installation of apps from the terminal. These are examples of this problem:

ratanak@ratanak-walker:~$ sudo apt-get install httrack
Reading package lists... Done
Building dependency tree       
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 httrack : Depends: libhttrack2 (>= 3.48.24) but it is not going to be installed
 rstudio : Depends: libjpeg62 but it is not going to be installed
           Depends: libgstreamer0.10-0 but it is not installable
           Depends: libgstreamer-plugins-base0.10-0 but it is not installable
           Recommends: r-base (>= 2.11.1) but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

The following packages have unmet dependencies:
 r-base : Depends: r-base-core (>= 3.4.0-1xenial0) but it is not going to be installed
          Depends: r-recommended (= 3.4.0-1xenial0) but it is not going to be installed
          Recommends: r-base-html but it is not going to be installed
          Recommends: r-doc-html but it is not going to be installed
 rstudio : Depends: libjpeg62 but it is not going to be installed
           Depends: libgstreamer0.10-0 but it is not installable
           Depends: libgstreamer-plugins-base0.10-0 but it is not installable
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

I notice that these problem started when I started installing program r.

Solution 1:

This problem is solved.

sudo apt install --fix-broken
sudo apt-get update
sudo apt-get upgrade

Thank you! Cheers!

Solution 2:

run

sudo dpkg --configure -a
sudo apt update && sudo apt-get autoclean && sudo apt-get clean && sudo apt-get autoremove
sudo apt dist-upgrade -y

tell me if that helps, cheers!

Solution 3:

Try using sudo apt full-upgrade -- that will remove some packages if necessary.
