I mean "sudo apt-get update"

You have some PPAs activated as repositories to download software packages, but three of them do not contain software for the Ubuntu release that you are running. You have to deactivate them from your list of repositories.

What is the output of the commands (to be executed in a terminal window):

grep bhdouglass /etc/apt/sources.list /etc/apt/sources.list.d/*.list
grep gwibber-daily /etc/apt/sources.list /etc/apt/sources.list.d/*.list
grep octave /etc/apt/sources.list /etc/apt/sources.list.d/*.list

Not all PPAs support all releases and they should be removed

Can you help with this problem?
