reinstalling network-manager in ubuntu
troubleshooting my internet connection, I deleted network-manger, and now I'm trying to reinstall. So with no internet conection from my installation, I booted off a livecd, and chroot into my installation.
Code:
ubuntu@ubuntu:~$ sudo mount /dev/sda6 /mnt/hd
ubuntu@ubuntu:~$
ubuntu@ubuntu:~$
ubuntu@ubuntu:~$ sudo mount /dev /mnt/hd/dev
mount: /dev is not a block device
ubuntu@ubuntu:~$
ubuntu@ubuntu:~$
ubuntu@ubuntu:~$ sudo mount --bind /dev /mnt/hd/dev
ubuntu@ubuntu:~$ sudo mount --bind /proc /mnt/hd/proc
ubuntu@ubuntu:~$ sudo mount --bind /sys /mnt/hd/sys
ubuntu@ubuntu:~$
ubuntu@ubuntu:~$ sudo chroot /mnt/hd
root@ubuntu:/#
but I'm trying to install network-manager, and or update the install and I'm getting these errors.
Code:
root@ubuntu:/# sudo apt-get install network-manager-gnome
sudo: unable to resolve host ubuntu

seems from my install I have a connection problem as I'm not able to ping any host eg: google.com yahoo.com. However, when I do ifconfig, I get my ip configuration and everything seems just fine.
Code:
root@ubuntu:/# ping 192.168.1.254

on the other hand, from my livecd I'm connected and browsing the internet. Seems some DNS resolution maybe? so I added two DNS server to my resolv.conf file
Code:
root@ubuntu:/# echo 208.67.222.222 > /etc/resolv.conf && echo 208.67.222.220 >> /etc/resolv.conf
root@ubuntu:/#
root@ubuntu:/#
root@ubuntu:/# cat /etc/resolv.conf
208.67.222.222
208.67.222.220
but still unable to ping a host by name in the internet. restarted my ip configuration, but still no go...
any help appreciated |
