skype crashes in ubuntu 12.04

This helped me:

sudo apt-get install libasound2-plugins:i386

From here: Skype 4.2 extremely unstable / unusable on Debian sid


I had the same problem, this is what I did to overcome it:

  1. Remove previous installations of skype:

    sudo apt-get autoremove --purge skype
    
  2. Do an overall update:

    sudo apt-get update && sudo apt-get upgrade
    
  3. Download the latest version of skype

    Start Skype and it should work fine
