GUI problems

[zaidst]

Hello Everybody

I have ubuntu 11.10 beta 2 with no gui or any desktop enviornment
I have only GDM and LightDM , and the default is GDM .
On my login screen .. I have only 2 choices :
1. Recovery Console
2. User Defined Session

Now , I wan to install Gnome ... When I enter the tty2 session and write the following command sudo apt-get install gnome .. here what the last line in the result is :

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

I listen to his advice

sudo apt-get update

W: Some index files failed to download. They have been ignored , or old ones used instead.

sudo apt-get install gnome --fix-missing

E: Aborting install

........................

Sorry guys i can't quote all the results bcz it's hundredes of lines and i can't copy them to another pc

Please Help

I'm here to listen to your Recommendations

Thanks in Advanced

Do you have an internet connection? Try

ping google.com

(or any other site)

and see if it responds

It seems no

ping www.google.com

ping: unkown host www.google.com

ping 192.168.1.1

//my network ip

connect : Network is unreachable

So , it seems i have no access even to the network
I face Network problem

What to do in that case ??

Is it a wired network? In that case, executing dhcpcd will probably be enough.

For wireless, do the following in tty:

iwconfig

there you should see your wireless card, probably called wlan0. If it's called otherwise, change the name in the next commands.

ip link set wlan0 up

Now it depends on your encryption:

for no encryption:

iwconfig wlan0 essid "networkname"

WEP:

iwconfig wlan0 essid "networkname" key "0241baf34c"

WPA ASCII key:

iwconfig wlan0 essid "linksys" key "s:pass1"

WPA:
If your /etc/wpa_supplicant.conf file is correct,

wpa_supplicant -B -Dwext -i wlan0 -c /etc/wpa_supplicant.conf

otherwise, you need to do first

wpa_passphrase networkname "my_secret_passkey" > /etc/wpa_supplicant.conf

And as a final step, you can do

dhcpcd wlan0

how to execute dhcpcd ?

[sanderd17]

just execute

dhcpcd

or maybe with the device

dhcpcd eth0
