In order to use a fix a fan issue on a Toshiba laptop that's supposed to work, I get this error:

Reading package lists... Done

Reading state information... Done
N: Ignoring file 'google.listgksu' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension
N: Ignoring file 'google.listgksu' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension
E: Unable to locate package sensors-applet

What should I do?

Thank you!
