Jason,

I’m hoping you’ll be able to help me out with some wifi issues I’ve been having.  I’ve installed the latest jessie release, and connman works great initially.  However, as soon as I install the Robotics cape so, connman dies, and I get a warning like:

Error getting services: The name net.connman was not provided by any .service fi

Error getting VPN connections: The name net.connman.vpn was not provided by any 

Error getting peers: The name net.connman was not provided by any .service files

Error getting technologies: The name net.connman was not provided by any .service 

filesconnmanctl> 

Whereas before I only got the VPN connections error.  James forwarded me the connman.service file that you “hacked” and that seemed to work once, but now I’ve messed around with it again and that hack doesn’t seem to work.

Any ideas?

Going back to a known-good image is always good. There have been many fixes and Robert has some images newer than on latest-images. 

Can you post your .service file contents?

Hi Kurt,

Grab last night's build:

https://rcn-ee.net/rootfs/bb.org/testing/2016-12-27/iot/

There's still a few corner cases i'm debugging and tricky for users to
actually cause. (I also need to add a restart to the service file,
during first time bootup when the ssh key's take too long to
generate.)

Regards,

Jason,

I’ve flashed back to the 12/18 image multiple times, and keep getting the same problem with connman.  I’ll try the latest image from yesterday that Robert suggested.

Here on the contents of my .service file:

[Unit]

Description=Connection service

DefaultDependencies=false

Conflicts=shutdown.target

RequiresMountsFor=/var/lib/connman

After=dbus.service network-pre.target systemd-sysusers.service

Before=network.target multi-user.target shutdown.target

Wants=network.target

[Service]

Type=dbus

BusName=net.connman

Restart=on-failure

ExecStart=/usr/sbin/connmand -n

StandardOutput=null

CapabilityBoundingSet=CAP_KILL CAP_NET_ADMIN CAP_NET_BIND_SERVICE CAP_NET_RAW C$

I believe in some circumstances I saw the above line preventing startup. I'm sure there is a good reason for it however. :-)

ProtectHome=true

ProtectSystem=full

[Install]

WantedBy=multi-user.target
