  • Ethernet device not managed

    3 answers



I am playing around with networking component of latest Ubuntu. I faced the above issue when I tried to manage networking devices with NM.



The command line output is



root@sankar:~# nmcli d s
DEVICE TYPE STATE CONNECTION
eth0 ethernet unmanaged --
eth1 ethernet unmanaged --
eth2 ethernet unmanaged --
lo loopback unmanaged --


I tried couple of solutions(comment #36 and #30) given in https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1638842.



Any help is highly appreciated

          I had this happen with an installation of Ubuntu Server 18.04 (Which uses netplan) and then adding a desktop window manager GUI (in our case, xubuntu-core^).



          No Manner of re-configuring or nmcli would make these devices managed.



          The solutions you tried were close, we found that if you follow the answer located here: Ethernet device not managed
          and note that the location of the 10-globally-managed-devices.conf is in the folder /user/lib/ you will be able to active those network devices by blanking the 10-globally-managed-devices.conf file with:



          sudo mv /usr/lib/NetworkManager/conf.d/10-globally-managed-devices.conf /usr/lib/NetworkManager/conf.d/10-globally-managed-devices.conf_orig


          and



          sudo touch /usr/lib/NetworkManager/conf.d/10-globally-managed-devices.conf


          And restarting network-manager or rebooting.

I've never really liked "Adventurer" as a job, and would like my story to have a kind of unlikely-hero vibe. besides the common "Traveling merchant", what kinds of artisans or professionals in fantasy would have a reason to move around the world (or at least visit other settlements)? First time posting, so let me know what to improve. Thanks!

I do not come from a particularly wealthy family, (very low middle class), and was only able to afford my education via school loans/scholarships and working low-wage jobs, with no support from my family or anyone else. I realize some scholarship/loan programs extend into grad school. But I don't think those cover all costs. Now I'm lucky enough to have a decent-paying salary in industry, along with benefits and living on my own, and I'm thinking one day (sooner rather than later) I'd like to try my hand at research or continue my degree, but these things cost money, in addition to my regular living expenses. I read posts here often about academic people being in positions of choosing between these crazy research grad programs, some in Japan, or Ireland (while they currently live in the U.S./U.K.) then moving around between countries/universit...
