While I was installing Ubuntu 14.04 I had some issues with graphic card drivers so I needed to install drivers from root, I created adsl connection using pppoeconf.
Now when I boot up my PC I have two connections, my regular connection which I use and ifupdown(eth0) which was created using pppoeconf.
How can I delete eth0 connection so it doesn't bothers me anymore?
Open your file manager and go to /etc/network/. Once there, you have to edit the file interfaces like this:
sudo gedit /etc/network/interfaces
or
gksu mousepad /etc/network/interfaces
and delete all entries in there except for auto lo / iface lo inet loopback.
The following lines
auto lo
iface lo inet loopback
have to be the only entries present in /etc/network/interfaces.
Next you should edit a second file located in /etc/NetworkManager/NetworkManager.conf. Use this code in a terminal window:
sudo gedit /etc/NetworkManager/NetworkManager.conf
or
gksu mousepad /etc/NetworkManager/NetworkManager.conf
Look for this entry [ifupdown] and edit the entry to look like this:
[ifupdown]
managed=false
Reboot and reconfigure if necessary your network using the network applet from system tray.
lo I had eno1 ininterfaces. I am using 16.04
Open terminal and enable super user mode.
nano /etc/NetworkManager/NetworkManager.conf
The contents of the file will be like this:
[main]
plugins=ifupdown,keyfile,ofono
dns=dnsmasq
[ifupdown]
managed=true
Please change the plugins section to:
plugins=keyfile,ofono
Restart the network manager:
service network-manager restart
It worked for me, I hope it will work or you too.
