It appears Skype has been upgraded (see here). First remove your old skype
$ sudo apt-get --purge remove skype:i386
$ rm -r ~/.Skype/
Then go here https://www.skype.com/en/get-skype/ and choose 'Get Skype for Linux DEB'.
Once the .deb
file has been downloaded, right-click on the .deb
file, and open with Ubuntu Software Centre. If this isn't listed, click on 'Open with Other Application' > 'Show Other Applications' > 'Ubuntu Software Centre'. Once loaded into Ubuntu Software Centre, click the 'install' button.
Once the installation is complete, either launch from the terminal with
$ skypeforlinux
or click on the top left icon on the launcher on the Ubuntu desktop. Type in 'skype', and click on the Skype icon under 'Applications'. This will launch your newly installed skype.
