Installation error for freeswitch.service and docker.service

[chillihilli]

On a fresh Ubuntu 16.04 server the installtion via bbb-install fails with following main errors: Job for freeswitch.service failed because the control process exited with error code. See "systemctl status freeswitch.service" and "journalctl -xe" for details. Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

Can anyone please advice me tracking down the root of the errors?

Kind regards Michael

I found the solution: http://docs.bigbluebutton.org/2.2/troubleshooting.html#freeswitch-fails-to-start-with-a-setscheduler-error

Now even the docker.service is working :-)

After rebooting freeswitch.service ist up and running but docker.service is not:

~#systemctl status docker.service ● docker.service - Docker Application Container Engine Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: e Active: failed (Result: start-limit-hit) since Do 2020-05-07 23:27:52 CEST; 3 Docs: https://docs.docker.com Process: 4173 ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd Main PID: 4173 (code=exited, status=1/FAILURE)

Any ideas what might be wrong here?

If I do sudo bbb-conf --check the out put is:

I can't tell why your docker service does not start. Probably there went something wrong in the installation process. Looking at the date this issue was reported, I'm not very confident that we will still be able to figure out, what happened. But it's worth to retry the installation and look closely at the output for any problems reported.

Here are some hints, that might be helpful:

• It is possible (and good practice) to download the install script first and to start it from the local disk. By doing so it's easy to copy the output into a file:

  $ wget -q https://ubuntu.bigbluebutton.org/bbb-install.sh
  $ chmod 755 bbb-install.sh
  $ sudo ./bbb-install.sh 2>&1 | tee bbb-install.out
  

  This way you can lookup problems later and check closely what went wrong.
• You can check if all services are running by issuing a

  $ sudo bbb-conf --status
  

  If any service is missing, BigBlueButton will not work.
• Please check, if <my_ip> and the resolved IP address from <my_hostname> are identical:

  $ dig <my_hostname> IN ANY
  

  If the IP address reported here and the IP address configured locally do not match, you are likely to sit behind a firewall or NAT device.

There is some troubleshooting documentation available. Your problem might be already documented there.
