I use Ubuntu 14.10 desktop X64 and when I switch from single usermode to init3 mode I face no network connection so i use the command NetworkManger to start it but I get this error

(NetworkManager:3789): GLib-WARNING **: GError set over the top of a previous GError or uninitialized memory.
This indicates a bug in someone's code. You must ensure an error is NULL before it's set.
The overwriting error message was: Key file does not have group 'connectivity'

what is the meaning of this error and how to solve the man issue ?

  • Please upgrade to a supported release of Ubuntu (15.10) and report back. Thanks. – Seth Feb 14 '16 at 17:30
