    Unhappy NetworkManager does not work

    Dear ubuntu community,


    I have a problem with my ubuntu installation that prevents me from going online. I am not the proest of Linux users and after researching, trying out different thing and failing, I decided to ask you. Maybe you can help.

    1. Setup: I have a MacBook Pro (2016) with dual boot. And I am using the ubuntu 20.04 Focal Fossa Beta version. Since I had the exact same problem with Mint 19.3 (except my phone hotspot worked), I dare say that I do not think the problem arises from the Beta status of the OS. I am also not able (in both) to use my touchpad, but that's for another day.

    2. The problem: I can install ubuntu without any major problems, while using an external mouse. I can, however, not access the internet. When I enter my password, I will be prompted again and again to authenticate.

    3. Self diagnosis: After researching and trying out, I found out, that the network manager is not working.

    Code:
    fub@fub:~/Desktop$ systemctl status NetworkManager.service
    ● NetworkManager.service - Network Manager
         Loaded: loaded (/lib/systemd/system/NetworkManager.service; enabled; vendor preset: enabled)
         Active: failed (Result: exit-code) since Thu 2020-04-09 06:14:40 EDT; 36s ago
           Docs: man:NetworkManager(8)
        Process: 6468 ExecStart=/usr/sbin/NetworkManager --no-daemon (code=exited, status=1/FAILURE)
       Main PID: 6468 (code=exited, status=1/FAILURE)
    Apr 09 06:14:40 fub systemd[1]: NetworkManager.service: Scheduled restart job, restart counter is >
    Apr 09 06:14:40 fub systemd[1]: Stopped Network Manager.
    Apr 09 06:14:40 fub systemd[1]: NetworkManager.service: Start request repeated too quickly.
    Apr 09 06:14:40 fub systemd[1]: NetworkManager.service: Failed with result 'exit-code'.
    Apr 09 06:14:40 fub systemd[1]: Failed to start Network Manager.
    4. Tried solutions: I tried to activate the Network Manager, but it failed.

    Code:
    fub@fub:~/Desktop$ sudo service network-manager start
    Job for NetworkManager.service failed because the control process exited with error code.
    See "systemctl status NetworkManager.service" and "journalctl -xe" for details.
    And I tried to reinstall it. I downloaded it, while in macOS and put it on a USB stick. Also didn't work.

    Code:
    fub@fub:~/Desktop$ sudo dpkg -i das_hier_network-manager_1.22.10-1ubuntu1_amd64.deb 
    (Reading database ... 149231 files and directories currently installed.)
    Preparing to unpack das_hier_network-manager_1.22.10-1ubuntu1_amd64.deb ...

    Job for NetworkManager.service failed because the control process exited with error code.
    See "systemctl status NetworkManager.service" and "journalctl -xe" for details.

    Processing triggers for dbus (1.12.16-2ubuntu2) ...
    Processing triggers for man-db (2.9.1-1) ...
    Furthermore, I tried to reinstall ubuntu, but during the installation I already had the error.

    5. Despair: I don't know, where to go from here. Can you help? I'd really appreciate it since I want to try to use Linux in my every-day life, due to it's awesomeness.

    Thank you, best and stay healthy

    Re: NetworkManager does not work

    Hello Cheese Sandwich.

    Please use code tags - if you are using New Reply button - highlight text and use the # button in the text box header.

    If using Quick Reply then [code] at the beginning and [/code] at the end.

    Thread moved to Apple Hardware Users.

    Will you please explain what your instructions do and why you think it will help the OP, I do not think it is clear that he is using the brcmfmac firmware and the OP states and posts information that suggests network manger is not working.
