After upgrading 11.10 to 12.04, I noticed that Skype 18.104.22.168 was no longer on the sidebar of icons. Found it in Dash and it runs but no sound. Figured I'd check Ubuntu Software Center and reinstall but it indicates a different version - 22.214.171.124-0precise3 - and indicates that Skype is not installed. Attempting to go ahead and install errors saying that it can't install when skype is already installed.
sudo apt-get remove skype
...then it says
Package skype not installed
Tried to update apt-get but that didn't make any difference.
Seems like it would be best to straighten this all out so it's right and, presumably, the newer version is probably better to have installed. Can anyone step me through how to do so?
