Hi ,

open a terminal and give this command

~$ gksudo software-properties-gtk

at the opened window in the first section (updates) make sure that the CD/DVD rom entry is unticked (not marked) and also goto "Other Software" section and Untick - Unmark the entries with "CDrom"

Then close the window and run in terminal

~$ sudo apt-get update

~$ sudo apt-get dist-upgrade

Thank you.

Or run:

gksudo gedit /etc/apt/surces.list

the top few lines references the install CD which can be used as a package source. You can comment those out by putting a hash symbol ('#' is a hash symbol) at the left of the line. Save the new file and close gedit then run:

sudo apt-get update

Should now be smooth.

You have a typo here Andrew.

And as this bug : https://bugs.launchpad.net/launchpad/+bug/80895

is still open, we have to be careful twice. :-)

I wonder when this bug will be closed (fixed) and we can edit our answers to correct the typos.
