    Good morning! (it’s morning in NYC)

    Last night my new install of Antix19.4 was working on my Lenovo T500. This morning, on boot, I got the error message

    Unable to create an interface to connman on the system bus.
    CMST will not be able to communicate with connman.

    resulting in no internet access.

    Google wasn’t much help and I looked into this forum, checking that recommended commenting out wasn’t necessary, but still with the issue.

    I have several small issues as I migrate to Antix but this one is new this AM and its something of a roadblock. I’ve looked on the forum and see a similar problem that someone had with wifi but I’m using eth0 and suggestions there didn’t apply.

    Relevant dmesg -T text available at

    Any help would be welcome.

    Thanks,

    Alan

    Hi.
    Try restarting connman service
    sudo service connman restart
    I would disable the startup script for network-check-antix so it doesn’t create conflicts if you are always connected using ethernet.
    If you also have a wireless card, and want to give ethernet priority, edit /etc/connman/main.conf and add this line at the end of the file:
    PreferredTechnologies = ethernet,wifi

    Yup, that worked!

    Thanks!

    I’ll let you know about your suggested fixes.

    Later:

    I disabled the startup script for network-check-antix and I edited /etc/connman/main.conf to insure ethernet priority, then I rebooted.

    The “unable to create an interface…” error was not issued on boot this time but I still had to restart connman.

    See when yo restart your system if connman is on:
    service connman status
    If it is disabled, maybe it was disabled frm starting. Try
    sudo update-rc.d connman defaults

    If this still doesn’t get connman to start at boot, then switch to ceni. Either with the gui or the terminal
    antix-wifi-switch --cli ceni
