I'd like to have this bug's importance been raised because right now I cannot log into any WiFi network having WPA2 Enterprise authentication (TLS certificate). When trying to connect to such a network (e.g. "eduroam"), NetworkManager crashes immediately.

Helge Jung,

It's unclear that you're seeing the same bug as is reported here. Could you please file your own for your crash? You may need to enable apport to do this, which can be achieved by following the steps in https://wiki.ubuntu.com/Apport#How_to_enable_apport.

You may also wish to try changing the certificate format for the certificate file you're using, in case this has any incidence on the crash; usually, you should have some level of information that might help in /var/log/syslog: reporting your own crash will attach this file, which will make things much easier to debug.

Thanks in advance!

Mathieu,

I'm also using the 11.10 beta and apport tried to report the crash but launchpad suggested that I want to report something similar to this bug report. As the error looks pretty much the same, I just added myself to this report instead of filing a new report.

I already tried using other certificates but as the very same certificate file works fine in 11.04 I suppose this is a 11.10 bug. The bug seems to happen when network-manager loads a connection setting with a TLS certificate which would fit to network-manager crashing at boot-time. Nevertheless, I will file a bug after I reproduced the bug at home.

[Mathieu Trudel-Lapierre (cyphermox)]

Please do; this will allow me to verify it's really the same issue, or fix each separately in a much easier way.

For my case network manager crashed shortly after logging in to lightdm but appeared to recover as I am connected ok via wifi.

[Mathieu Trudel-Lapierre (cyphermox)]

It's unclear to me how this might happen. It seems like the dbus daemon isn't available, which causes most daemons like NetworkManager to not be able to function properly.

If you're still seeing this issue, could you please run "dpkg -l dbus" and report whether it lists the dbus package being installed (you would see "ii" at the beginning of the line with the dbus package name.
