每次安装新版总是有些问题。一个个来解决。

   1： sudo apt-get install ia32-libs lib32asound2 libqt4-core libqt4-gui
   2： wget -O skype_Ubuntu-current_amd64.deb http://www.skype.com/go/getskype-linux-beta-ubuntu-64
   3： sudo dpkg -i skype-Ubuntu-current_amd64.deb

到这一步出现错误信息：

dpkg: dependency problems prevent configuration of skype:
 skype depends on lib32stdc++6 (>= 4.1.1-21); however:
  Package lib32stdc++6 is not installed.
 skype depends on lib32gcc1 (>= 1:4.1.1-21+ia32.libs.1.19); however:
  Package lib32gcc1 is not installed.
dpkg: error processing skype (--install):

因为少了两个 lib ,分别是 lib32stdc++6 和 lib32gcc1。 打开 Ubuntu software center ，安装之后，再sudo dpkg -i skype-ubuntu-current_amd64.deb ，就可以了。还是2.2版的，，看来skype对linux的支援还不够。
