[Bug 405413] Re: Network connections disappear from list after making available to all users

 

Well, this is fixed by way of a redesign of NM in 0.9; the Fix is
available in Oneiric which will be released in October.

Unfortunately, it will not be possible to backport these changes.

Note that what you're seeing may have been due to configuration of eth0
or other devices in /etc/network/interfaces. If your connections don't
need to be configured there and you want to use NetworkManager, you
should be able to safely remove or comment them out.

** Changed in: network-manager (Ubuntu)
       Status: Confirmed => Fix Released

Title:
  Network connections disappear from list after making available to all
  users

Status in “network-manager” package in Ubuntu:
  Fix Released

Bug description:
  Binary package hint: network-manager

  In the Gnome Network Manager Applet, when I edit connections and make
  them available to all users, they disappear from the Network
  Connections list, and I can no longer enable them.  A file with the
  name of the connection appears under /etc/NetworkManager/system-
  connections, but the connection never comes online.  I never see any
  output in my log files that indicates the system is attempting to
  bring these connections online.  I have tried this with both wireless
  and wired connections.

  The set of steps to reproduce this is as follows:

  1. Right click on the network manager applet and click on Edit Connections.
  2. Click on Add and configure a new connection and fill in the information or click on Edit and edit existing one, changing some part of the network configuration
  3. Make sure the Available to all users box is checked.
  4. Click Apply.

  Auto eth0 disappeared and stopped working after reconfigured it for a
  zerconf local network and clicked on Apply.  In addition, the same
  thing happened when I attempted to create new connection provides for
  the interface eth0.  After this, I attempted to do the same thing with
  wireless connections, just to see if the behavior would be the same -
  it was.

  After doing this, the contents of /etc/NetworkManager/system-
  connections looked like this:

  -rw------- 1 root root 550 2009-07-26 20:25 Auto Burton
  -rw------- 1 root root 335 2009-07-26 21:45 Auto eth0
  -rw------- 1 root root 284 2009-07-26 20:27 Auto eth1
  -rw------- 1 root root 297 2009-07-26 20:45 Auto eth2
  -rw------- 1 root root 303 2009-07-26 21:22 Foobar
  -rw------- 1 root root 307 2009-07-26 21:22 Foobar2
  -rw------- 1 root root 324 2009-07-26 20:46 Wired connection 1

  Wired Connection 1, Foobar, and Foobar 2 are connections I created
  from scratch and attempted to make available to all users, after Auto
  eth0 disappeared.  Auto Burton was an existing wireless network
  profile that I attempted to make available to all users.

  Uninstalling network-manager with the --purge option and deleting this
  directory before reinstalling puts the system back into he default
  state, but the problem returns as soon as I attempt to make a
  connection available to all users again.
