"activate networking" : broken from recovery mode

[dino99]

I have found that activating networking from the grub revovery mode is not possibLe.
So this mode is useless to update/upgrade/fix a broken intallation.
Maybe it is related to systemd not taking care of the feature.

Get that probLem with yakkety

This has also been met by other users, like: http://ubuntuforums.org/showthread.php?t=2253852&p=13172673#post13172673

Looks like systemd is concerned here.

Does not have that issue with Wily

I tested this on current xenial, and my ethernet interface does get configured via DHCP, through the "ifup -a", it's not yet getting to the NetworkManager fallback. I then commented out the "ifup -a" from /lib/recovery-mode/options/network and re-ran it, and NM gets brought up.

So I cannot reproduce this and I need more information what goes wrong for you. Please start recovery mode, select "root shell", and run

   sh -x /lib/recovery-mode/options/network > /var/tmp/network.debug 2>&1

Then reboot and attach /var/tmp/network.debug here. Thanks!

Tested the command with both xenial & yakkety 64 bits:

xenial:
- after validating the command, i got dropped back to a frozen recovery menu
- ctrl+alt+del to exit after a while
- check nautilus , and cant find a network.debug output

yakkety:
- the command immediatly abort with: 'read only system'
- starting that command with 'sudo' does not help either.

So in both cases, it lokks like a right issue
