Petr Michalec, your best bet is to file a new report given the different environment and error message via a terminal: ubuntu-bug network-manager
I no longer have the original computer that was reproduced with (I was also using two WLAN NICs simultaneously), and was not able to reproduce on later versions of Ubuntu with different hardware. Hence, the issue is likely environment specific. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1438003 Title: (1) Creating object for path '/org/freedesktop/NetworkManager/ActiveConnection/0' failed in libnm- glib.
