Red Hat Bugzilla – Bug 807248
User connections get lost during upgrade
Last modified: 2012-03-28 08:33:26 EDT
Description of problem:
While upgrading from F15 to F17 branched all VPN settings got lost.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Have a F15 install
2. Configure some VPNs, e.g. PPTP or OpenVPN
3. Upgrade system to F17
No more VPN connections available.
Configured VPN connections should still be available. From 0.9.1.90 to 0.9.3.x or 0.9.4 is a minor upgrade, so there should be a clean upgrade path and no loss of configuration.
As Data loss is considered of high severity in bugzilla, I am setting severity accordingly.
BTW: Where is the configuration stored? Is there a way to restore it manually?

Was it really upgrade from 0.9.1.x to 0.9.3.x? Because there's no change in storing connections in latest version. And the migration would have been already done.
There was a major change between 0.8 and 0.9. NM 0.8 used 2 settings services, that provide connections to NM daemon - one was inside NM itself and handles system connections, the second was in nm-applet (user connections). The user connections were stored in GConf. You would find them in ~/.gconf/system/networking/connections. Or use gconf-editor /system/networking/connections.
The user connection are not used any more in 0.9 (they can be emulated) and only
one settings service exists.
The migration of stored data was done by nm-applet (src/applet.c by
nm_gconf_move_connections_to_system() function). And migration apps/nm-applet/stamp key in GConf is set to 3, marking the migration as done.
If you reset the stamp to 2 and run nm-applet it will force the migration again.

Yes, it was from F15 to F17 branched. F15 was first release with GNOME 3 and therefor required NM 0.9.

They are still there, I can see them on the harddrive or in gconf-editor, but not in nm-connection-editor.
While looking at the connections I realized it is not just VPN but also bluetooth and others, basically all user connections. nm-connection-editor only shows system-wide connections from /etc/sysconfig/networking-scripts

This cannot be true. Connections I added in 0.9/F15 were written to gconf - unless they were marked as system-wide connections.
Where are user connections stored in 0.9? gsettings?

Thanks, that brought me my VPN connections back. On the other hand it also brought ancient Wifi networks back which I had already deleted a while ago.

I just found them in /etc/sysconfig/networking-scripts.
I think there is fundamentally wrong here:
1. Connections should not be changed from private to public without user permission.
2. The migration should not just write random stuff to a /etc/sysconfig. This should still require root privileges.
One more thing I realized: The migration did not bring back an OpenVPN connection I added two weeks ago in F15. This indicates that by that time NM was already using the new configuration.

Right, it wasn't actually doing the right thing; your previous connections had been deleted, this was just a kludge recreating them from your old F14 state.
Oh. Hm... did you actually "upgrade" from F15 to F17, or did you reinstall? Since even user connections are stored in /etc now, if you did a reinstall, then they'd be lost, even if you had separately preserved /home.
You are right, I formatted my / partition. I found the connections I was looking for in my backup, copied them back and things are fine. Sorry for the noise.
I still think there is something wrong with the migration though. Old 0.8 user connections should not be migrated to 0.9 system-wide connections. But this is a different issue.
They're not migrated to system-wide connections, they're migrated to user-connections-that-are-stored-in-/etc (but still marked as being specific to a single user).
I don't really love that arrangement either, but that's how it is for now.
