I have freshly installed and updated ubuntu on raspberry pi 3.

Neither sudo ls nor sudo apt-get install pose any problem, but executing:

sudo nmcli device status


Error: Could not create NMClient object: Could not connect: Permission denied

  • Did you get to the bottom of this? I'm seeing the same when trying to do anything with sudo apt – DaveStephens Jul 22 '19 at 21:10
  • @DaveStephens, i did not. I gave up and went with raspbian – Pompey Magnus Jul 24 '19 at 0:00

I had a similar problem on Ubuntu 18.04 LTS. I fixed it with snap connect network-manager:nmcli as described in man-page


You have Network-Manager installed as a Snap, and the Snap's CLI plug has not been granted permissions. You can solve the problem by running snap plug network-manager:nmcli.
