I am running Debian 9 with XFCE4 on Dell XPS 15 (9560). Recently I ran into trouble with apt. If I try to run anything using apt-get install, the following always return:
william#debian:~$ sudo apt-get install vim
Reading package lists... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
vim : Depends: vim-common (= 2:7.4.488-7+deb8u3) but 2:8.0.0197-4+deb9u1 is to be installed
E: Unable to correct problems, you have held broken packages.
I have tried running sudo apt-get update, sudo apt-get upgrade, sudo apt --fix-broken install, sudo apt-get clean, and etc, etc.
Some of them return messages like this:

Whenever I try to install a new package/upgrade, I see the following error:

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
libc6 : Breaks: libc6:i386 (!= 2.33-0ubuntu5) but 2.34-0ubuntu3 is installed
libc6:i386 : Breaks: libc6 (!= 2.34-0ubuntu3) but 2.33-0ubuntu5 is installed

I'm new to Linux, and am pretty stuck at the moment. Any help would be tremendous. Thanks!
For installing pip3 I am following apt update process.
But I am getting output in terminal:
$ sudo apt-get update
Reading package lists... Done

Reading state information... Done
E: Unable to locate package python3-pip
Tried all available solutions on stackoverflow.
Please suggest any solutions.
Sometimes the sources.list file is not configured properly, so if none of solutions work than try this:
Type in terminal, gedit etc/apt/sources.list. A file will open, check if these given lines are present or not in that file:
deb http://deb.debian.org/debian buster main
deb-src http://deb.debian.org/debian buster main
deb http://deb.debian.org/debian-security/ buster/updates main
deb-src http://deb.debian.org/debian-security/ buster/updates main
deb http://deb.debian.org/debian buster-updates main
deb-src http://deb.debian.org/debian buster-updates main
In my case these were missing, this means the apt-get command had no mirrors configured to pull and update packages. These lines are the links to Debian repositories from where packages are pulled.
Copy and paste these lines into that file and save and close it.
Now run sudo apt-get update and than run sudo apt-get upgrade. Once process finishes run sudo apt-get install -y python3-pip. This will install pip3 without any error.
Please run an update and upgrade,
sudo apt update && sudo apt upgrade
Hopefully, this will fix the issue. if this doesn't work you can always update the source list manually.
I know that there are already several questions similar to this, but none of its solutions worked for me. Hence, after a lot of web searching and trying out different stuff, I simply decided to open a Stack Overflow question myself.
Basically, I had ROS Kinetic working on my Ubuntu 16.04 machine and it suddenly started giving me several errors when I tried to build my catkin workspace. After trying several stuff, I decided to uninstall ROS with sudo apt-get remove ros-* and install it again, according to the tutorial http://wiki.ros.org/kinetic/Installation/Ubuntu.
I leave below the full execution of the installation commands:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies.
ros-desktop-full : Depends: ros-desktop but it is not going to be installed
Depends: ros-perception but it is not going to be installed
Depends: ros-simulators but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
Running sudo aptitude install ros-desktop-full also did not work. If I execute sudo apt-get install ros-desktop, it says that ros-desktop has unmet dependencies. If I try to install those dependencies, they also have unmet dependencies.
Would really appreciate if anyone could help me. Thanks!
For all those suffering from the same problem, I was not able to solve it and ended up reinstalling Ubuntu on my computer. After this, everything worked correctly.
My advice would be to just reinstall Ubuntu right away, I would have lost less time if I had done it immediately.
I am truly struggling to install npm. I have installed the nodejs package successfully, but still my operating system UbuntuĀ 15.10 (Wily Werewolf) doesn't recognize the npm command like it is shown below, even though after several update attempts with sudo apt-get update:

It looks an infinite tree of dependencies. Is there a solution to fix it?

Use aptitude instead of apt-get. It is more intelligent. It not only will handle downgrading conflicting packages for you, but it will make a series of recommendations asking you which of many possible suggested working scenarios you would like.
sudo aptitude install myNewPackage
If you don't have aptitude on your machine yet, get it with
sudo apt-get install aptitude
