I have that file too but it's not related to what we're trying to do.

I wrote managed=true in my message above. (Andrei's message had false.)

My permissions and the owner are the same as yours.

My /e/n/i file has eth0. That's why we are changing NetworkManager.conf,
to get it to cooperate with /e/n/i.
If you don't want to define eth0 in /e/n/i, then you can try Andrei's
suggestion. (If you do, you might have to set specifics of your wired
interface using the NetworkManager applet.) However, your /e/n/i file
below defines eth0!

That last line defines eth0.
