Problems with LiquidSoap (1.1.1) when Manually Installing Airtime 2.4 from GitHub - Airtime Support Discussions on Sourcefabric Forum

Hello,

I've tried several times to manually install 2.4 with the same problem. Basically, Media Monitor and the Dashboard all work but never the stream. The "Getting Information from the Server..." message is always displayed on the Stream Preferences page, and the "On Air" button is never lit.

My install process is basically:

1. create the server (Ubuntu 12.04 LTS) run apt-get update and apt-get dist-update

2. git clone https://github.com/sourcefabric/Airtime.git

3 ~/Airtime/install_full/airtime-full-install

The install seems to run smoothly, configures Icecast passwords and host, and fails with the following airtime-check-system:

I've checked the host values in /etc/airtime/api_client.cfg and airtime.conf, and verified that liquidsoap.cfg is present (with the owner "pypo" and the proper permissions.)

Although "sudo service airtime-playout start" seems to be okay, "sudo service airtime-playout restart" returns:

Restarting Airtime Scheduler: start-stop-daemon: warning: failed to kill 19894: No such process
Done.

Any ideas? The above error "No module named pypofetch" seems odd.

you need to use sourcefabric version of liquidsoap

Hello, thank you for replying!

I still don't completely understand how to get liquidsoap updated (without installing airtime from package... which works)

How do I update? I get the following:

ubuntu@machine:~$ dpkg -i liquidsoap_1.1.1~precise~sfo-1_amd64.deb

Preparing to replace liquidsoap 1.1.1~precise~sfo-1 (using liquidsoap_1.1.1~precise~sfo-1_amd64.deb) ...
Stopping liquidsoap channels: no script found in /etc/liquidsoap
Unpacking replacement liquidsoap ...
Setting up liquidsoap (1.1.1~precise~sfo-1) ...
Starting liquidsoap channels: no script found in /etc/liquidsoap
Processing triggers for ureadahead ...

Hi Eric, you have the latest version of our Liquidsoap package, which looks OK. When using the scripts in install_full the default is to use localhost, e.g:

AIRTIME_STATUS_URL = http://localhost:80/api/status/format/json/api_key/%%api_key%%

so that suggests to me you have files in /etc/airtime/ left over from a previous install which reference http://airtime.isourblock.org:80

I would recommend that you back up or move these /etc/airtime files out of the way before running the install_minimal/airtime-uninstall script. Then try running the install from git again.

By the way, if you want to install Airtime 2.4.1 you should checkout the 2.4.x branch on github. By default I think you will get the master branch, which is the place to work on features for the next development version.

Cheers!

Daniel

Hi Daniel,

I think you're right that there were some left over files in the airtime directory, but I don't think this was causing the problem. I ran airtime-uninstall and remove the /etc/airtime and /srv/artime dirs and had the same issues. I've attached the terminal output of the installation and tails for the liquidsoap and playout logs on a completely clean Ubuntu server... kind of banging my head on this one.

I suggest to try automated installation http://en.flossmanuals.net/airtime-en-2-3/automated-installation/
this is recommended for ubuntu
let's see if this works

Eric Pugh

I think I got it working. What I did is edit line 2 in python_apps/pypo/timeout.py

That seemed to clean up the "no module named pypofetch" error, and everything installed correctly. (the fix on my Airtime fork)

Thanks!

hoerich

that rocks! good to hear

Howdy, Stranger!
