NetworkManager error "corrupted double-linked list" when starting openvpn

English Network/Internet
1

Hello everyone,

I have bought a Thinkpad E485 and installed Opensuse Tumbleweed with xfce desktop (the same problem occurred with gnome shell as well).

Here is my problem, everything works well except the vpn. I am in China and i need to use vpn quite often for work and I always use openvpn via the command line. When i use wifi only, the connection is stable but when I start openvpn, the network manager goes crazy. It just disconnects from the wifi, reconnects, disconnects, reconnects, etc… In a loop.

Openvpn tells me the connection is ready but when I check journalctl -fu NetworkManager:

Full log https://pastebin.com/xYg3c6Bt

I can see a core-dump at the beginning of the log so i guess the process is just crashing in a loop.

Is there anyone who got this issue before?

Thanks in advance.

Looks like this is an upstream problem, see: https://bugzilla.suse.com/show_bug.cgi?id=1107197

3

As the problem is apparently triggered by using libcurl, workaround would be disabling connectivity check in NM.

4

And how do I do that? I see no such option in KDE NM

5

man NetworkManager.conf, scroll to Connectivity section.

6

So I guess its this entry:

[connectivity]
uri=http://conncheck.opensuse.org

Will try and report back!

Hello,

I have been offline for quite a while since I posted. Sorry about that.

I have switched to wicked to manage my network, and even with the vpn, it remains stable.

The version that I had installed was tumbleweed snapshot 20180916 and everyday I run zypper ref && zypper up. Should I use zypper dup instead to avoid those problems in the future?

Went back to NetworkManager and it seems to work well after the update and restarted my computer.

Thanks for your answers. I really appreciate.

Yes, never use ‘zypper up’ as it will not always replace all packages
needing replacement.
