The overwriting error message was: Key file does not have group 'connectivity'

I am seeing the same issue after upgrading to 14.04.

I also have the same issue after upgrading to 14.04, and my wifi disconnecting from time to time. I have to power off and power on again the wireless.

Status changed to 'Confirmed' because the bug affects multiple users.

Is there a quick fix for this or do i need to wait for a new release?

Tried the following with no luck:
1. Removed the vpn-connection and added it again (multiple times)
2. Removed and installed network manager all over again

My Ubuntu version: 14.04

Error I get on connecting to VPN: Error: Connection activation failed: invalid VPN secrets.

var/log/upstart/network-manager.log has:

Each time I reboot my Ubuntu desktop I need to run NetworkManager to start my network and it shows this error.

yaseer@yaseer-M11BB:~$ sudo NetworkManager

Hi!

I had the same issue and in my case I fixed with the following steps:
(previous these steps I purged sendmail because I needed only postfix)

- searched all the remains of sendmail and removed from the places that I thought it would affect the boot process
- on /etc/network/interfaces I deleted all the other lines added before - there remained only 2 lines (default ones)
- purged the network-manager (but before I saved all the needed packages for a reinstall from an USB stick - .deb files)
- added packages: plasma-nm, plasma-widget-networkmanagement, network-manager-gnome
- checked all the remained errors from /var/log/upstart/ logs - in my case there were none left after reboot

Any clue on this. my notebook has been having problems with networking.

My clue is that I am using a USB wifi in place of the built-in wifi -- which is faulty (poor performance and probably not working on certain frequency band). Occasionally, I forgot to bring my USB, and has to turn on the builtin wifi. But, I almost never intended to run two wifi adapters at the same tme.

But, even the interface is down, it is still configured. My theory is it has something to with the various networking problems I have been having. In particular with public wifi -- many times I dont get the wifi login redirection . In several Starbucks, it will not see the Starbuck signals once it lost them (probably just after network in-active sleep). Though, it can acquire the next door signals but not re-acquiring google-starbuck. Very weird.

I suspect that multi adapter related because the original poster also run multiple networks. I am not really. But, I am also a developer. I plug in my phone to PC to either develop app and such, or use its data in a pinch when my wifi does not work.

I am fairly technical -- used to work on TCP/IP and such 20 years ago. If someone wants to cooperate with me... i will pitch in.

My laptop (ubuntu studio 64bit) just suddenly decided to have this problem.

The network menu shows "NetworkManager is not running", if i try to run NetworkManager directly, it shows this error and exits.

I tried futzing around with the config files, didn't work :/

Hi - I'm seeing this problem on an up-to-date Linux Mint 17.2, Rafaela installed. And as current as update manager and apt-get network access allow it.

Most concerning is that he

$ apt-get update

Command is failing on some URL-s. I've put a description on StackOverflow if someone has ideas on how to resolve this before there's a permanent fix.

The problem I'm seeing eventually clears, so I thought it was dns cache related. After finding this error in the network-manager log I don't wonder if it might go deeper. (Thanks for listening)

@delt - Yes I've been having this problem come and go for at least 4 months now. There's a thread on the Linux Mint forums but i can't give a reference tonight because the site is down for maintenance. I don't know that that would be helpful though. Until I found this error in my log file, I was thinking there was a problem with the DNS because it happens on "popular" URLs like Google.com, Yahoo.com, GitHub and dl.google.com just yesterday.

Hi!
I had the same issue. I can't use my wireless.

sudo cat /var/log/upstart/network-manager.log

I use flowing command, setup my wireless.
$ sudo wpa_supplicant -i wlan0 -c wpa_supplicant.conf

Please quickly fix the problem, thanks you.

I am seeing this issue with two machines. First my new desktop machine, with a brand new install of xubuntu - 14. 04. Wired networking only, no wireless. Second, my work laptop, a ThinkPad x220 with wireless networking. Wireless was working when I was at the office this morning, but when I lifted the lid just a moment ago, there was no more network manager. A check of the message shows the same segv crashes and the same error messages that others were reporting above. A good deal of web searching shows that this might be a regressed bug from an earlier release of network manager. Any prognosis from the developers as to a possible fix?

Hi,

I'm having this same problem as of today.. I didn't have any issues before with wireless. But today after I did update and upgrade I rebooted and now I have this issue? Anyone know how to fix this?

As oft today, I also have the issue. I did an upgrade on Friday and today it dropped working.

Hi,

I've been having this problem since Jan. 30th, possibly after an update but I'm not sure. I'm running on Ubuntu 14.04 LTS. It is impossible to get NetworkManager starting, I'm getting the same error as mentioned above whenever I try sudo NetwordManager.
For the time being, I managed to connect to the Internet via sudo dhclient etho0 for the wired connection and via wpa_supplicant for the wireless connection but this is not satisfactory and only works at home (I would have to configure manually any other wireless network).
I uninstalled/purged and reinstalled NetwortkManager but the problem remained.
I hope this issue can be fixed quickly because it is really troublesome.

As of today, I also have the issue. I did an upgrade on Friday and today it dropped working.
Please quickly fix the problem, thanks.

There is a regression in some libs:
The workaround is here:

Today, I back to follow version, it work.

#sudo apt-get install network-manager=0.9.8.8-0ubuntu7

fromthe thanks!!!

14.04, affected by the bug, manually starting NetworkManager helps, but I do get the error message:

I get this problem on Trusty Tahr without enabling the pre-release updates.

I can confirm that sfbanjo's solution worked for me.
