[SOLVED] Coffee Brewer Beeps

The annoying beep means: "Descale me please" - at least that's what I thought. And hey presto, the descaling did the trick. 

  Tried to install the .deb after download. However the browser stated that the installation was deprecated. I had to:

dpkg -l

In the list I found the name of the .deb:

google-chrome-stable

Then:

dpkg -r google chrome stable

Finally:

dpkg -i google-chrome-stable_current_amd64.deb
