[Chad Peterson]

I have the same problem on GalliumOS running on an Acer Chromebook R11.
I tried the above method (#16) and it did not work.

[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.

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

[axel]

There is a fix for this:
https://ubuntuforums.org/showthread.php?t=2305819

add a file to the /etc/modules-load.d directory to have the modules
loaded into the kernel at boot.  I just created a file called
netfilter.conf and put the following in it:

nf_nat_pptp
nf_conntrack_pptp
nf_conntrack_proto_gre


Is it safe to use this solution? I don't know what those three entries mean.

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

[KF Lee]

My network consists of:
2: enp8s0:  mtu 1500 qdisc mq state UP group 
default qlen 1000
inet 10.1.1.1/24 brd 10.1.1.255 scope global enp8s0
3: wlp4s0:  mtu 1500 qdisc mq state UP group 
default qlen 1000
inet 192.168.99.2/24 brd 192.168.99.255 scope global wlp4s0
5: ppp0:  mtu 1484 qdisc pfifo_fast 
state UNKNOWN group default qlen 3
inet 220.132.100.42 peer 168.95.98.254/32 scope global ppp0

and it seems all work ok except the service networking status keep showing:
   Active: failed (Result: exit-code) since Sun 2018-03-25 20:47:42 CST; 53min 
ago
 Docs: man:interfaces(5)

-n "$(ifquery --read-environment --list --exclude=lo)" 
 Main PID: 953 (code=exited, status=1/FAILURE)

cant find a fix and lead to also see in service NetworkManager status:
NetworkManager[933]: nm_device_get_device_type: assertion 'NM_IS_DEVICE (self)' 
failed

but the point is the network function normally, are these two issues
related and what's the cause ?

Not sure I agree with #13 because message comes AFTER network is up:

It seems it is a harmless message due to NetworkManager not having
connection to any network

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

[Diego Diniz L. de Oliveira]

Guys...I got this problem solved by running these commands...

Install WICD to manage the network

sudo apt-get install wicd-gtk

Stop and disable Network-Manager

sudo systemctl stop NetworkManager.service
sudo systemctl disable NetworkManager.service

and uninstall avahi-autoipd and isc-dhcp-client using synaptic

But now I'm having two problems, one, system setting is not working
'cause NetworkManager is disabled, two wicd sets a random ip even it's
configured as static so when I turn on the system or restart it, I have
to disconnect and connect again to wicd recognize the righ ip.

Same error. My computer has no wireless card connected. I've tried a lot
of things (changed network card for a new one, changed to a different
distribution). Maybe is a hardware (motherboard) problem.

  Any suggestion?

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

[Michael F Winthrop]

I am receiving numerous NM errors on startup, that I captured from
/var/log for one boot on Aug 16 18:10: I ask if the preserved ".files in
the home/user/ directories could be responsible for these errors?

In the captured "fail" list, NM is the main event per this thread 
(nm_device_get_device_type: assertion 'NM_IS_DEVICE (self)' failed)

The problem got more pronounced after:

sudo add-apt-repository ppa:kubuntu-ppa/backports
sudo apt update

This was added after plasma repeatedly dropped the window ornaments.

I had made the unfortunate "upgrade" from kubuntu 14.04 with kxstudio
and decided to do a clean install to clean up the previous mess, leaving
kxstudio out (because kxstudio is skipping 16.04 in favor of 18.04):

I re-installed kubuntu 16.04,3 from disk downloaded 5 days ago
(1.562.112KB) preserving the /home/dad partition as well as a copy of
the fstab: (shows what was preserved during install on /dev/sd8

 sudo /etc# cat fstab

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).

  I have tried an Ubuntu VM with the same packages related to networking and 
the exact same releases (same repositories), the crash never happens; the

desktop vs Ethernet for the VM.

  Any suggestion?

  Hello,
  On Ubuntu 15.10 4.2.0-35, with network-manager 1.0.4-0ubuntu5.3
  My WiFi connection is very unstable and I have to  often restart 
NetworkManager service (~ a dozen times every day...):
