Unable to install Skype on 64bit Ubuntu [duplicate]

12.10 and newer

I had that same issue and what helped was to enable the 32-bit architecture by doing this:

sudo dpkg --add-architecture i386
sudo apt-get update

then I was able to install skype via the Canonical Partner Repository:

sudo add-apt-repository "deb http://archive.canonical.com/ $(lsb_release -sc) partner"
sudo apt-get update && sudo apt-get install skype

First of all you have to enable i386 architecture before running the below commands on your Ubuntu 64 bit system.

sudo dpkg --add-architecture i386

Then run the below commands on terminal to install skype.

Ubuntu 13.10

sudo sh -c "echo 'deb http://archive.canonical.com/ saucy partner' >> /etc/apt/sources.list.d/canonical_partner.list"
sudo apt-get update
sudo apt-get install skype

Ubuntu 14.04

sudo sh -c "echo 'deb http://archive.canonical.com/ trusty partner' >> /etc/apt/sources.list.d/canonical_partner.list"
sudo apt-get update
sudo apt-get install skype

I suggest to remove skype-bin first completely and install Skype as follows.

Run following commands in Terminal

sudo apt-get remove skype skype-bin

sudo apt-get install libxss1  

wget http://www.skype.com/go/getskype-linux-ubuntu-64/skype-ubuntu-precise_4.1.0.20-1_amd64.deb

sudo dpkg -i skype-ubuntu*.deb

 12.10 and above and in particular 17.04:

Download the deb package

If it isn't installed already install gdebi :

sudo apt update && sudo apt upgrade
sudo apt install gdebi

then cd to the Downloads directory and run gdebi for the downloaded deb:

sudo gdebi –n skypeforlinux-64.deb

(Or for an approach that doesn't even require installation of any extra software) :

sudo dpkg -i skypeforlinux-64.deb

you may instead just right click on the downloaded file go into properties and set the default program to open this sort of file to gdebi (which is recommended in the meantime in 17.04) and then simply double click the file and when gdebi opens and finishes loading the file click install (you will be prompted for your password)

skype is not from ubuntu.it is a third party software supported by canonical foundation so edit your source.list using

$sudo gedit /etc/apt/source.list

then add the following link into your source list

deb http://archive.canonical.com/ubuntu $(lsb_release -sc) partner
deb-src http://archive.canonical.com/ubuntu $(lsb_release -sc) partner

$(lsb_release -sc) replace with your ubuntu name. Save it. Then update your repository using

$sudo apt-get update

now run the following command to install skype

$sudo apt-get install skype

this will install skype and skype.bin.
