    ๐Ÿ—„ Deprecated Features

    • ๐Ÿš€ The contents of /etc/airtime/cloud_storage.conf and /etc/airtime/rabbitmq-analyzer.ini have been moved to the main /etc/airtime/airtime.conf file and the env specific symlink is no longer needed. See below for instructions on how to migrate from a pre-release that created those files.
    • ๐Ÿš€ As per the announcement in the 3.0.0-alpha.5 release notes we are dropping Ubuntu 14.04 (Trusty) as a supported platform.
    • โœ‚ Removed Amazon S3 storage support.
    • โœ‚ Remove "Record & Rebroadcast" from ui.


    ๐Ÿ“„ The main installation docs may be found at They describe a "developer" install using the bundled install script.

    ๐Ÿš€ We are preparing packages for supported distros and you can take those for a spin if you would like to. Usually the packages get built pretty soon after a release is published. If the current version is not available from the below sources you should wait for a while until they get uploaded.

    โšก๏ธ Please reference these links for further information on how to install from packages. The install docs will get updated to show how to install packages once we have validated that the packages work properly and when the packages are available from a repository allowing you to automate updating to a new version.

    โšก๏ธ Updating

    โšก๏ธ See the docs for complete information on updating. Please ensure that you have proper backups and a rollback scenario in place before updating.
    โšก๏ธ If the update does not go smoothly, it may cause significant downtime, so you should always have a fallback system available during the update to ensure broadcast continuity.

    ๐ŸŒ If you installed from GitHub you can git pull in your local working copy and re-run the ./install script with the same --web-root and --web-user arguments you used during the initial install. Tarball users can leave out the git pull part and just call the new version of the install script.

    โšก๏ธ Updating from 3.0.0-alpha, 3.0.0-alpha.1 and, 3.0.0-alpha.2

    ๐Ÿ”ง The configuration file structure has changed. Please move the contents of the /etc/airtime/cloud_storage.conf and /etc/airtime/rabbitmq-analyzer.ini files into the main /etc/airtime/airtime.conf. In all known cases you need to add the following section to the file.


    ๐Ÿšš You can then remove the files and the symlink.

    rm /etc/airtime/cloud\_storage.conf \ /etc/airtime/rabbitmq-analyzer.ini \ /etc/airtime/production

    ๐Ÿšš While you're at you may also want to remove the amazon_s3 section if it was in any of the files.

    Analyzer grabs all the needed info from the main airtime.conf file starting with 3.0.0-alpha.6.

    Known Issues

    โ†ช The following issues may need a workaround for the time being. Please search the issues before reporting problems not listed below.

    Installer Issues

    ๐Ÿ“ฆ The installer is generally a bit unstable, we hope to be able to offer some reasonable packages at some point. Some of the GUI driven parts before the first login are also in a somewhat questionable state, ymmv.

    ๐Ÿš€ For now the installer distro selection is pretty good at auto-detecting your os and usually does an ok job depending on your distro. You should usually not need to pass a --distribution and --release parameter, those are still supported for the time being but their use is not recommended.

    ๐Ÿ’ป The ui works best if you don't use it in an opinionated fashion and change just the bare minimal.

    ๐Ÿ“„ If you want a secure environment you should work through the preparing the server docs (up until the dragons) and be prepared to fix some of the issues the installer gets wrong manually by hacking the config file after the fact.

    ๐Ÿ— If you want to skip the installer GUI completely you can configure LibreTime using airtime_mvc/build/airtime.example.conf as an template. Due to some python/PHP differences you must remove all comments from the example to use it ๐Ÿ˜ž. You'll also have to create some folder structures manually and check if the music dir got properly created directly in the database. Referencing a second install -fiap install on a non productive system for reference can help with this type of bootstrap.

    Media-Monitor config needs manual removing

    ๐Ÿšš If you are using the install script you should most likely remove the [media-monitor] config section from your /etc/airtime/airtime.conf file to ensure you do not run into the problems described in
    ๐Ÿš€ #450. We recommend you do this before running the update since there are no known LibreTime releases that depend on the config value.

    Outdated silan reports unreliable cue in/out information

    ๐Ÿ— Out of the box the installer installs a broken, outdated version of silan on some Debian based Platforms (ie. Ubuntu). This affects all distros supported by the installer except Debian testing which has the silan 0.3.3 and CentOS which does not have upstream packages and you may either install from source or use the 0.3.3 packages from RaBe APEL.

    ๐Ÿ‘€ Check your version of silan by running silan --version. This should report 0.3.3 or higher. If not please see the Silan Installation wiki page for more details & workarounds.

    ๐Ÿ“ฆ To date silan 0.3.3 or higher is in Debian testing & Ubuntu Bionic. You can check the upstream progress the Debian PTS and Ubuntu launchpad. This section will get removed once the package is in stable.

    ๐Ÿ‘ Liquidsoap Support

    ๐Ÿ— Libretime currently only supports liquidsoap < 1.3.0 out of the box. If you install a current version of liquidsoap using OPAM or through the Rabe Liquidsoap Distribution for CentOS (RaBe LSD) you will most likely have liquidsoap 1.3.2 or 1.3.3 installed.

    #352 reports that liquidsoap < 1.3.0 can exhibit issues on some Debian based installs. One fix for the issue is to install liquidsoap 1.3.0 and to use the following patching steps. Kyle from silan fame is taking the needed steps to get liquidsoap maintained again in Debian so we expect the situation to improve over time.

    You can check your liquidsoap version by running liquidsoap --version.

    If you already have liquidsoap >= 1.3.0 you have a couple of options.

    Liquidsoap 1.3.0 Patchset (#192)

    ๐Ÿ‘ You can patch your installation of LibreTime to support liquidsoap 1.3.0.

    An up to date patch is available through GitHub and can be applied to an unpacked tarball as follows.

    cd libretime-3.0.0-alpha.6/ curl -L | patch -p1

    Git users can pull from the branch at master...radiorabe:feature/liquidsoap-1.3.0 directly.

    Install old liquidsoap from opam (#192)

    โฌ‡๏ธ You can downgrade an OPAM install of liquidsoap by running the following command.

    opam install "liquidsoap\<1.3.0"

    ๐Ÿ‘ No watched folder support

    ๐ŸŒ Currently LibreTime does not support watching folders as described in the manual. Uploading files through the web interface works fine and can be automated via a REST API. Re-implementing watched folder support is on the roadmap. Please consider helping out with the code to help speed things along if you want to use the feature.

    ๐Ÿ‘ No line in support

    ๐Ÿ‘ This feature went missing from LibreTime due to the fact that we based our code off of the saas-dev branch of legacy upstream and support for recording hasn't been ported to the new airtime analyzer ingest system. #42 currently tracks the progress being made on line in recording.

    Playout wont work if locale is missing

    ๐Ÿ‘€ Some minimal OS installs do not have a default locale configured. This only seems to affect some VPS installs as they often do not have a locale setup in the default images provided.

    ๐Ÿ“š You can set up the locale using a combination of the following commands. You might also want to consult the documentation of your VPS provider as it may contain an official way to set up locales when provisioning a VPS.

    # Set locale using systemds localectllocalectl set-locale LANG="en\_US.utf8"

    โšก๏ธ These instructions do not seem to work on all Debian based distros so you might need to use update-locale as follows.

    #Purge all locales but en_US.UTF-8
    sudo locale-gen --purge en_US.UTF-8
    #Populate LANGUAGE=
    sudo update-locale LANGUAGE="en_US.UTF-8"

    Lack of i18n toolchain is disturbing

    ๐ŸŒ Some translations might miss the tarball. They didn't get lost but the build chain needs fixing. Work is in #301 and additional work is needed as it has become clear that we probably want to support bidirectional translation syncing with zanata.


    ๐Ÿฑ I would like to use this space to extend a warm welcome to our new Maintainers @paddatrapper, @frecuencialibre and @ned-kelly. We are happy to have you on board. Thank you very much for helping maintain LibreTime โค๏ธ
