PSA: Ubuntu 18.04 (Bionic) nightly packages are available, Trusty is deprecated

[Juan Navarro]

In the last weeks I've been working to port all Kurento packages to Ubuntu 18.04 (Bionic), and since a couple of days all CI builds seem stable and preliminary End2End tests are passing!

All tasks were tracked with the Github's Projects feature, here: https://github.com/orgs/Kurento/projects/1

It was a good opportunity to use the Github feature and experiment how useful it might prove to be for the Community. We might use it again in the future, to let users know about progress on the topics they are interested in.

Regarding the new Ubuntu version, nightly packages are already available in a bionic repository for apt-get. Just follow the Nightly installation instructions, as always:

https://doc-kurento.readthedocs.io/en/latest/user/installation_dev.html

(docs are being published right now so it may take some minutes to appear)

Note these packages are just the result of first porting efforts. There are still some missing stuff to do, before considering it a 100% port:

• None of the "extra" modules have been ported yet; i.e. the example plugins that are provided for demonstration purposes, such as kms-chroma, kms-crowddetector, kms-platedetector, kms-pointerdetector.
  
  
• OpenCV plugins in Kurento still use the old C API. This still worked out fine in Ubuntu 16.04, but it doesn't any more in 18.04 for plugins that use external training resouces, such as the HAAR filters.
  
  Plugins that need to load external OpenCV training data files won't work. For now, the only plugin affected by this limitation in KMS seems to be facedetector because it won't be able to load the newer training data sets provided by OpenCV 3.2.0 on Ubuntu 18.04. Consequently, other plugins that depend on this one, such as the faceoverlay filter and its FaceOverlayFilter API, won't work either.
  
  I've not studied much about the issue here but I'm afraid the only way to solve this problem would be to re-write this plugin from scratch, using OpenCV's newer C++ API, which has support for the newer training data files provided in recent versions of OpenCV.
  
  This issue probably affects other of the additional modules mentioned earlier. Those haven't even started to be ported.

Lastly, a deprecation notice for Ubuntu 14.04 (Trusty): Official support for Ubuntu Trusty is practically here (ends on April 2019, source: https://wiki.ubuntu.com/Releases)

It has become increasingly difficult for us to keep supporting Kurento on multiple Ubuntu versions at the same time, so we'll continue to strictly adhere to official LTS versions of Ubuntu. This means that starting now, all development focus will be for Ubuntu Xenial and Bionic. Trusty will stop receiving updates in its repositories and no new release versions of Kurento will be published for this version of Ubuntu.

Happy coding!

If I'm using "kms-omni-build" can I 

Can I use the "kms-omni-build" method within Ubuntu 18.04 and just change "xenial" to "bionic" in the "ubuntu.openvidu.io" repository definition ?

Vincent

[Juan Navarro]

Yes, you can follow build instructions as usual from the Developer Guide:

https://doc-kurento.readthedocs.io/en/latest/dev/dev_guide.html#building-from-sources

[Vincent]

I'm trying it now !

[Vincent]

I didn't investigate further, but it doesn't seem to compile :

I was on the master branch. Will now switch to the 6.9.0 release to see if it compiles.

[Vincent]

As per your OP, it chokes on OpenCV. How do I disable OpenCV-dependent modules from the omni build ? Thanks.

It was a problem of OpenSSL 1.0 vs. 1.1 dependency versions.

Build instructions updated for Ubuntu Bionic on the Developer Guide.

The old text indicated to install 'libssl-dev', but that package installs OpenSSL 1.1 under Ubuntu 18.04, which is incompatible with KMS.

Version 1.0 is required.

A better install method is to use 'mk-build-deps' and leave DPKG to resolve all dependencies as needed under each version of Ubuntu.

Please if you still find problems building the code, open a new thread

Hello Juan,

Installation via apt doesn't work for me :(

Original docs states:

deb [arch=amd64] http://ubuntu.openvidu.io/dev $DISTRO kms6

In this case I'm getting following error:

Err:6 http://ubuntu.openvidu.io/6.9.0 bionic InRelease

E: Failed to fetch http://ubuntu.openvidu.io/6.9.0/dists/bionic/InRelease  403  Forbidden [IP: 52.218.84.210 80]

E: The repository 'http://ubuntu.openvidu.io/6.9.0 bionic InRelease' is not signed.

N: Updating from such a repository can't be done securely, and is therefore disabled by default.

N: See apt-secure(8) manpage for repository creation and user configuration details.

In case changed as follows:

deb [arch=amd64 trusted=yes] http://ubuntu.openvidu.io/dev $DISTRO kms6

The error is

Err:11 http://ubuntu.openvidu.io/6.9.0 bionic/kms6 amd64 Packages

  403  Forbidden [IP: 52.218.97.115 80]

E: Some index files failed to download. They have been ignored, or old ones used instead.

This URL http://ubuntu.openvidu.io/6.9.0/dists/bionic/kms6/binary-amd64/Packages gives

<Message>Access Denied</Message>

If accessed in the browser ....

[Juan Navarro]

The documentation states it clearly:

# KMS for Ubuntu 14.04 (Trusty)
DISTRO="trusty"

# KMS for Ubuntu 16.04 (Xenial)
DISTRO="xenial"

This PSA is named "(Bionic) nightly packages are available"... Bionic packages are in development and haven't seen a release yet.

I have used this installation guide https://doc-kurento.readthedocs.io/en/latest/user/installation.html

Haven't noticed it is 'latest' and not 'stable'

Will try to build from sources ...

[Juan Navarro]

Yes, building from sources will work, follow https://doc-kurento.readthedocs.io/en/latest/dev/dev_guide.html#building-from-sources

Note you can save the trouble by installing nightly packages, as linked in the announcement:
https://doc-kurento.readthedocs.io/en/latest/user/installation_dev.html#kurento-media-server

[solom...@gmail.com]

Thanks a million!

Was able to install nightly packages to Ubuntu 18.10 without much hacking :)

Everything seems to work so far :)

[Francois Baret]

I installed the Nightly kms on my Ubuntu 18.04. Now I would like to use the one2many tutorial but I think I cannot start the kms with the same docker image:

docker run -d --name kms -p 8888:8888 kurento/kurento-media-server:xenial-latest

Do you have another docker image for Bionic? Or can you guide how to run the nightly kms otherwise?

Thanks!

[solom...@gmail.com]

Why do you need docker if native Nightly kms is already installed?

[IF] native KMS works on port 8888 already, maybe this is port conflict?

i.e. you need to use -p 8888:8889 and not -p 8888:8888 ?

[Juan Navarro]

Also, to use nightly builds with Docker use this image: kurento/kurento-media-server-dev
https://hub.docker.com/r/kurento/kurento-media-server-dev/tags

Starting from KMS 6.9.1 we'll have moving tags with major, minor and patch versions, so you can choose to use
kurento/kurento-media-server-dev:latest  # Get always the latest thing, even if it breaks backwards compatibility
kurento/kurento-media-server-dev:6  # Get all updates on the 6.x version (non-breaking changes)
kurento/kurento-media-server-dev:6.9  # Get all patches from the 6.9 release (none in this case, next release will be 6.10 directly)
kurento/kurento-media-server-dev:6.9.1  # Get all nightly builds from this development version
kurento/kurento-media-server-dev:6.9.1-<Timestamp>  # Actual nightly builds

Similarly with normal future release images, but not yet.

If you want to have the latest nightly version at all times, I recommend you use either kurento/kurento-media-server-dev:6 or kurento/kurento-media-server-dev:latest

But if you use kurento/kurento-media-server-dev:latest, beware the (distant) day we publish version 7.0.0, you update without paying attention, and everything in your application breaks :-)

[Ayaan]

Awesome. Any estimated official release date for 6.9.1?

[Xiaolin Zhang]

I am trying to fix this on Ubuntu 18.04.2，it seems the OpenSSL is upgrade to 1.1. So, I made the following patch:

- https://github.com/Kurento/kms-elements/pull/15

- https://github.com/Kurento/kurento-media-server/pull/11

Can anyone review these two PR? Thanks?

[Priyanka Gopalghare]

I have installed Kurento media server on Ubuntu 18.04 (Bionic) and coturn server as well. I am trying to run simple "Hello World Example" or  "one2one-Call" examples from Kurento tutorials on that server. 

But, I am not able to view the Remote stream, there is no error in the console of both of the user.

We are migrating to the Ubuntu 18.04 as Ubuntu 14 Trusty is deprecated and Audio video sync problem was there, you have mentioned about the fix of that problem in the following discussion : https://groups.google.com/forum/#!topic/kurento/cKzgDVrAch4/discussion 

Please, help to resolve the issue.
