i tried installing the synaptic package manager i got this,

phani-system:/home/phani# apt-get install synaptic
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package synaptic is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package synaptic has no installation candidate

what i mean exactly is ,when i move to System->Administration i found only this options,login window,network,services,shared folders,time and date,user and groups thats it i find no synaptic manager,no software sources etc.,
could u please help me

What version of Debian are you using?
Post the output of:

cat /etc/debian_version ,and also cat /etc/apt/sources.list

i m using debian 5.0(lenny)


out-put of the second command is

#
# deb cdrom:[Debian GNU/Linux 5.0.0 _Lenny_ - Official i386 CD Binary-1 20090214-16:29]/ lenny main

deb cdrom:[Debian GNU/Linux 5.0.0 _Lenny_ - Official i386 CD Binary-1 20090214-16:29]/ lenny main

deb http://security.debian.org/ lenny/updates main
deb-src http://security.debian.org/ lenny/updates main

apt-cache policy synaptic gives me :

What do you get?

i got this

Ok the problem is with your apt sources.

Edit the file to look like this:

Notice i have commented out the install disc.
Also you can substitute the UK entry for a nearer mirror if you wish.

Save the file.
Then do apt-get update to make sure the file everything is working.
If you get no errors then do apt-get install synaptic

yahoo thanks a lot,i got synaptic package manager but there is no software souces option still,
and lastly one more thing,
when i open a dir it is getting opend in a seperate window instead of opening in the existing window,please help me in this also.

once again thanks a lot

I don't know what that means,i don't use synaptic myself.
You can add repositories to the apt sources file you you edited earlier.
I assume it is also possible to do this via the Gui in Synaptic.

Is this a problem?
What desktop environment are you using,KDE/Gnome/Xfce?
It will be possible to change window behavior.
You can always navigate files with the command line.

In Synaptic click on SETTINGS -> REPOSITORY

Man that looks more confusing than just manually editing the /etc/apt/sources.list to me..

I agree with farslayer. Just edit the file; except it's /etc/apt/sources.list

Perhaps you opened synaptic as a regular user, rather than as root user (or sudo, depending upon how your system is set up). When synaptic is opened as a regular user it won't allow access to the repositories. When you open it does it ask for the administrative password? Because if it doesn't, and instead simply shows a warning that you're using it as regular user, then you'll run into issues such as not being able to access the repositories.

It appears that your whole Debian installation was based exclusively on the first CD (of over 25 CDs), and no repositories (except for the security update repositories). I'm guessing that has given you a pretty slender Debian. If possible, and if you have a high speed internet connection, you may wish to consider reinstalling using the Debian Net-Install disc (available from the Debian Net-install page), and, if you have a regular commonplace computer, then the i386 image is the one you wish to get. The net-install disc will connect to the internet, and connect to the repositories, and do a full install of Debian Lenny for you.

Or, if you'd rather not reinstall, then instead, via either synaptic or aptitude, make sure that the Gnome meta-package (or KDE, if you prefer) is installed. In synaptic, the Gnome meta-package ("gnome") is described as "The GNOME Desktop Environment, with extra components". Selecting this package will also select numerous other ones. Doing this will give you all the functionality that you've come to expect from a properly set up Linux operating system. If you can't get synaptic working for some reason, then simply entering "apt-get install gnome" in the terminal (as root/sudo) would do the trick.

Good luck with it.

have you clicked the 'reload' button in synaptic after editing '/etc/apt/sources.list'?
