I don't know what happened, but when I got back from suspend, suddenly network manager was deleted on my ubuntu 14.04. So, looks like it needs a reinstall, however, I don't have the packages saved anymore.

I did find the following page that probably would solve my problem:

How to reinstall network manager without internet access?

Only, there is a stumbling block: I can't open/edit /etc/resolv.conf.

My steps: 

xubuntu@xubuntu:~$ sudo mount /dev/sda2 /mnt
xubuntu@xubuntu:~$ sudo mount --bind /dev /mnt/dev
xubuntu@xubuntu:~$ sudo mount --bind /proc /mnt/proc
xubuntu@xubuntu:~$ sudo mount --bind /sys /mnt/sys
xubuntu@xubuntu:~$ sudo chroot /mnt
root@xubuntu:/# sudo cp /etc/resolv.conf /sda2/etc/resolv.conf
sudo: unable to resolve host xubuntu
cp: cannot create regular file ‘/sda2/etc/resolv.conf’: No such file or directory
root@xubuntu:/#

And if I try to edit via nano, the file that gets opened is File: /var/tmp/resolvXX5eDVsN.conf

What obvious mistake am I making here? Because I just don't see it. Anyone who will please help me?

This is happening for others also in this week...After a long research on this problem I'm deducting these possibilities:

Causes of the problem:

1) Incomplete installation. 2) Pre-released software might end up in causing so un-select it in software manager settings.

Solution : 1)Restart the network Manager. sudo service network-manager start

if this isn't work in your case download the following files manually from other pc and copy it to affected system. Click here to get those files. For 64 bit :

libnl-3-200_3.2.21-1_amd64.deb
libnl-route-3-200_3.2.21-1_amd64.deb
libnl-genl-3-200_3.2.21-1_amd64.deb

For 32 bit: 1. libnl-3-200_3.2.21-1_i386.deb.deb 2. libnl-route-3-200_3.2.21-1_i386.deb.deb 3. libnl-genl-3-200_3.2.21-1_i386.deb.deb Put them in a folder and in terminal go up to that terminal,these are Debian files so install using this command.

sudo dpkg -i lib*.deb

this will install all three files at a time. And now restart your system. Every thing works fine your network manager will come again! the actual link

The obvious mistake you made was mixing you mount point with the name of your block device. You can't do:

sudo cp /etc/resolv.conf /sda2/etc/resolv.conf

because /sda2 is non-existing directory. Earlier you did:

sudo mount /dev/sda2 /mnt

and /mnt (not /sda2) is the right directory for your copy operations. So do:

sudo cp /etc/resolv.conf /mnt/etc/resolv.conf
