Users of menu-applet replacement Cardapio will need to need to update their sources with a new PPA address in-order to continue receiving updates.
The change over announcement, made on the projects’ launchpad page, states that “[the] old PPA has been replaced with the more official-sounding ppa:cardapio-team/unstable”
This means that if you’re using the old PPA it will stop working in a few weeks time. To continue getting updates you’ll need to add the following, new PPA.
To do this open a new Terminal window and enter:
sudo add-apt-repository ppa:cardapio-team/unstable
