Sources.list

Hi Shreenesh.

The format of the cdrom line in /etc/apt/sources.list should be something like

deb cdrom:[Ubuntu 8.04 _Hardy Heron_ - Release i386 (20080423)]/ hardy main rest
ricted

To look at this file. In a terminal, type

cd /etc/apt
cat sources.list

Is there a line like that for a cdrom that is not correctly formatted? If you see what the problem is, here is how to fix it. First make a backup copy of the file with

cp sources.list sources.list.bak

then edit it with

gksudo gedit sources.list

Save the corrected file and try again with Update Manager.

If you see which line is wrong, but do not know how to correct it, just put # at the start of it.

Does this solve your problem? If it does please mark the question as Solved.

in source list it is given as "# deb cdrom:[Ubuntu 8.04 _Hardy Heron_ - Release i386 (20080423)]/ hardy main restricted
deb-src http://archive.ubuntu.com/ubuntu/ hardy main restricted #Added by software-properties"

I am Getting the following as an error " Error:Opening the cache (E:Type 'cd' is not known on line 53 in source list, The Sources of list could not be read.)"

This is My Sources.list File's Content

Hi Shreenesh,

As a root user, remove the last two lines of your /etc/apt/sources.list file, which means removing these two:

cd/
cd\
