[Bug 1568560] Re: nm_device_get_device_type: assertion 'NM_IS_DEVICE (self)' failed

[axel]

On the same machine but on another disk with Manjaro I don't have these
errors. I think the problem can be solved by upgrading to the new
version of network-manager.

I installed new realtec driver but still no result.

Can you please upgrade network manager in Kubuntu 16.04? It slows down
my system start.
