Trying to install network-manager

[NewToLinux]

Within the last couple of days, I have tried to install network-manager
on a Debian Jessie system as follows :-

apt-get update
apt-get install network-manger

but it failed as follows :-

Reading package lists... Done
Building dependency tree
Reading state information... 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:
network-manager : Depends: libpam-systemd but it is not installable
Depends: policykit-1
Recommends: ppp (>= 2.4.6) but it is not going to be
installed
Recommends: dnsmasq-base but it is not going to be
installed
Recommends: crda
Recommends: iputils-arping but it is not going to be
installed

E: Unable to correct problems, you have held broken packages.

Can anyone please help me to understand why I cannot
install network-manager.

Thanks.

apt-cache policy would be more revealing
imo, wicd works better

Code: Select all

Sources could explain exactly what the problem is, although apt policy would show all the sources not just those in the sources.list file.

Yes 'apt-policy' gives more info, and generally,

Code: Select all

E: Unable to correct problems, you have held broken packages. 

Indicates something is wrong with the sources.list file. Or some of the packages installed.
Usually that error message, also includes one that suggests:

Code: Select all

# apt update --fix-missing 

and

Code: Select all

# apt install -f 

Sometimes works, but it would be better to show the 'apt-policy' output, and/or also the /etc/apt/sources.list , if that is not correct, you will have problems fixing those packages.

Thanks to everyone for their contributions.

Here is what I get :-

% cat /etc/apt/sources.list
deb http://ftp.us.debian.org/debian/ jessie main non-free contrib
deb-src http://ftp.us.debian.org/debian/ jessie main non-free contrib

deb http://security.debian.org/ jessie/updates main contrib non-free
deb-src http://security.debian.org/ jessie/updates main contrib non-free

# jessie-updates, previously known as 'volatile' #deb
http://ftp.uk.debian.org/debian/ jessie-updates main contrib non-free
#deb-src http://ftp.uk.debian.org/debian/ jessie-updates main contrib
non-free #deb http://packages.linuxmint.com debian import

# Jessie backports #deb http://httpredir.debian.org/debian jessie-backports

% apt-cache policy network-manager

First of all, your sources.list is totally corrupted.
Example, these lines:

Code: Select all

http://ftp.uk.debian.org/debian/ jessie-updates main contrib non-free 
non-free #deb http://packages.linuxmint.com debian import

and so on.....

1 - save your corrupted sources.list

Code: Select all

mv /etc/apt/sources.list /etc/apt/sources.list.bad

2 - create /etc/apt/sources.list with this only to start

Code: Select all

deb http://ftp.uk.debian.org/debian/ jessie main non-free contrib
deb http://deb.debian.org/debian-security/ jessie/updates main contrib non-free
#

and check this

Code: Select all

apt-get update
apt-get install -f
apt-get install network-manager
