Skype

So if you've just installed or upgraded to the new version of Kubuntu (Wily Werewolf), you will notice that Skype runs fine but does not appear in the system tray as an icon. The workaround to fix this is to install the sni-qt package, but specifically the 32-bit version of the package (as Skype is a 32-bit app). To do this, open a terminal and type:

This will also install a dependency. Once this is installed, quit Skype and restart it to find the familiar green check in your system tray.

If you are using Skype on Linux and run into the error message "P2P connect failed" while trying to sign in, then your configuration file is very likely corrupt. The fix is to just delete the .Skype directory from your home directory and restart Skype. If you have anything worth saving inside this directory, you can simply rename it instead or alternatively, back it up elsewhere prior to deletion.

The version of Skype on my system is 2.0.0.72 and it was installed (and upgraded) from the Medibuntu repository. I'm pretty certain that the previous version was working fine.
