I recently updated ubuntu using the automatic update and it broke my network services. Luckily, after a lot of research and history I found the solution and want to post it for everyone who runs into this issue.
For starters after the upgrade when turning the computer on I got the message "Waiting for network configuration" and "waiting up to 60 more seconds for network configuration"
After it finally booted i had no network access wireless or on the lan. When i tried opening the network tool i got the error "The system network services are not compatible with this version"
FInally the fix that I came up with:
There appears to be an issue with the latest update of network manager. If you open software center, go to history, search keyword "Network" you will probably see "network-manager (0.9.4.0-0ubuntu4, 0.9.4.0-0ubuntu4.1)"
If you see this then you have the same problem as I did. The solution is to downgrade to version 3: Search in google "ubuntu network-manager package" and select the ubuntu.com link -> scroll down the page to "network-manager-dbg" select the precise (debug) ubuntu3 version.
Download the 4 related packages for your system (amd64 or i386):
network-manager (= 0.9.4.0-0ubuntu3)
network management framework (daemon and userspace tools)
or libnm-util2 (= 0.9.4.0-0ubuntu3)
network management framework (shared library)
or libnm-glib4 (= 0.9.4.0-0ubuntu3)
network management framework (GLib shared library)
or libnm-glib-vpn1 (= 0.9.4.0-0ubuntu3)
network management framework (GLib VPN shared library)
install each of them using the command "sudo dpkg -i FILENAME"
restart your computer and that should fix your problem! I hope this helps some and for those of you in the know can you please report this most recent update as broken? Thanks and good luck!
