I have a BeagleBone running Ubuntu. connman is getting in my way and I'd like to disable it. I deleted /etc/rc*/*connman, but somehow it's still getting started.
(Why am I trying to disable it? Because I'm trying to set a static IP address for eth0 in /etc/network/interfaces, but that doesn't work because evidently connman brings up eth0 first, with no address, which keeps ifup from working.)
You can also configure connman to ignore a specific interface.
I had to do exactly the same (static IP for eth0) and could do so by
configuring it in /etc/network/interfaces AND
by modifying (adding) a line in /etc/connman/main.conf:
NetworkinterfaceBlacklist=eth0,SoftAp0,usb0,usb1I never did figure out how to disable it, so I ended up just deleting it:
sudo apt remove connman
Now my conventional, static IP configurations (in /etc/network/interfaces) are working fine.
You may try running this in the command line:
sudo systemctl disable connman.service
After that other Network Managers should work. Normally Connman is designed for embedded devices.
This worked for me when I had some trouble with Connman on a fresh Ubuntu Studio 21.04 installation (lost Internet connection).
