How to run Windows Skype on Ubuntu using Wine?

I'm trying to use Skype on Ubuntu. I tried installing it in Wine. Installing it went fine, but when I try to login, it gives me error code 1814; resource name not found. What can I do to fix this?

To get the best result for running Skype for Windows on Linux using Wine, follow these steps. (Tested using Ubuntu 15.10, but it should work fine for earlier versions)

(1.9.1 was the newest Wine version upon writing this answer, you can try next versions for better result)

3. Download Skype 6.21.32.104 installer

Download Skype version 6.21.32.104. I cannot seem to find an official link for this. You can download it from this unofficial link. Put a comment if the link doesn't work anymore or if you find an official link.

Older versions of Skype are not supported anymore, they will fail to login. 7. version do not seem to work correctly in Wine.*

Click 'Install a program' and then 'install a non-listed program' in the bottom left corner.

Check 'use another version of Wine' and 'Configure Wine'. And click next.
Select Wine 1.9.1 and click next.

The Wine configuration Window appears after a few seconds. At the bottom of the Window, select Windows 8.1 and click 'ok'.
Back to the PlayOnLinux window: click 'Browse' and select the Skype installer you just downloaded. Click next.
Follow the Skype installer.
Select Skype.exe and click next to create a shortcut. Give the shortcut a name and click next again to finish the installation.
Click the Skype icon in the main PlayOnLinux window and click configure. In the general tab, add following to the Arguments field. Click another field so the arguments field is saved. (replace USERNAME and PASSWORD with your credentials).

Go to the tab 'Miscellaneous' and add export PULSE_LATENCY_MSEC=60 to "Command to exec before running the program"

Now you can run Skype from Playonlinux.

Native Skype on Ubuntu

There is a native Skype client for Ubuntu. You can open the Software and Updates applet included All Ubuntu flavors and click on the tab that says "Other Software". Make sure the Canonical Partners is ticked. Then you will be able to install the program through your favorite standard Ubuntu install method (software center, synaptic, or terminal).

or simply type:

sudo apt-get update
sudo apt-get install skype

enter image description here You can download it from the Skype for Linux download page. Choose the Ubuntu 12.04 version from the list of distributions.

This is by far the easiest way to install Skype on Ubuntu, but there are some disadvantages to this version, the main one being that Group video chat, or video conferencing is disabled. Video Chat between just two people works.
