Description

I tried the debian package, but i can't install it because some packages are missing:

E: Unable to locate package libavcodec59
E: Unable to locate package libavdevice59
E: Unable to locate package libavfilter8
E: Unable to locate package libavformat59
E: Unable to locate package libavutil57
E: Unable to locate package libswresample4
E: Unable to locate package libswscale6

I couldin't install them on 22.04 neither, because there are *58

So you're using ubuntu:24.04 but don't want to use containers and want to use autocue.
May I ask you to share your installation script?

Here's a script I used on a clean VM

OPAM_VERSION=2.2.1;
OCAML_VERSION=4.14.2;

sudo apt-get update;
sudo apt-get dist-upgrade;
sudo apt-get install --no-install-recommends -y curl ca-certificates patch unzip bubblewrap git bzip2 gcc make libc6-dev g++;
sudo curl -sS -L -o /usr/local/bin/opam "https://github.com/ocaml/opam/releases/download/$OPAM_VERSION/opam-$OPAM_VERSION-x86_64-linux";
sudo chmod +x /usr/local/bin/opam;
opam init --bare -n;
opam switch create "$OCAML_VERSION";
eval $(opam env --switch="$OCAML_VERSION");
opam install --confirm-level=unsaf…

Hi @NicoxDJ,
It seems you're trying to use the wrong packages.
For ubuntu:24.04 we have the following options

use containers;
use 2.2.4 from ubuntu repos;
install from opam;
build from source;
use release artifacts for the 2.3.x-rolling version.

For ubuntu:22.04 we have the following options

use containers;
use release artifacts for any version from 2.1.1 to 2.2.5;
use 2.0.2 from ubuntu repos;
install from opam;
build from source.

You're not supposed to use release artifacts for Debian on Ubuntu because the versions of the dependencies differ.
For example, for ubuntu jammy x86-64 you should use the release artifact available at https://github.com/savonet/liquidsoap/releases/download/v2.2.5/liquidsoap_2.2.5-ubuntu-jammy-1_amd64.deb.

The installation manual is available at https://www.liquidsoap.info/doc-2.2.5/install.html. It covers most of the advised methods.
I prefer to use container images, which are available at https://hub.docker.com/r/savonet/liquidsoap.
The building from opam is also a viable solution https://www.liquidsoap.info/doc-2.2.5/install.html#install-using-opam.

Well, right now i'm runing 2.2.4 from the Ubuntu distro, but i need to use AutoCue which requires 2.2.5, because it's crashing with error:

At /var/azuracast/autocue/autocue.liq, line 59, char 0-34:
let settings.autocue.cue_file = ()

Error 4: Undefined variable settings

I tried and I can't build 2.3.x by myself:

File "src/lang/queues.ml", line 28, characters 28-31:
28 |       try flush_elements_f (pop q :: elements) with Empty -> List.rev elements
                                 ^^^
Error: Unbound value pop
make: *** [Makefile:4: build] Error 1

I can't install 2.2.5 with opam neither:

containers is not an option too.

Can you help to fix at least one of these 3 errors?

I've manage to install it, after fixing this bwrap with this

Now i successfully installed 2.2.5-dev, but i've got another error:

At /var/azuracast/stations/station/config/liquidsoap.liq, line 43, char 18-32:
https_transport = http.transport.ssl()

Error 5: this value has no method `ssl`
  Its type is {unix : http_transport.{default_port : int, name : string, protocol : string}
}.

And if i commented it i've got:

At /var/azuracast/stations/station/config/liquidsoap.liq, line 454, char 8-14:
radio = ladspa.master_me(

Error 4: Undefined variable ladspa

and if i comment it i've got:

At /var/azuracast/stations/station/config/liquidsoap.liq, line 431, char 4-52:
    %mp3(samplerate=44100, stereo=true, bitrate=128),

Error 8: Unsupported format: %mp3(samplerate=44100, stereo=true, bitrate=128)

Why just nothing works :(

This will probably help ocaml/opam#5968, but may cause bugs later.
The update with the changes has been rolled up, then rolled back, and the current status of the new version should be tracked at https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/2064672.

I think you can try

sudo curl -sS -L \
  -o /etc/apparmor.d/bwrap-userns-restrict \
  https://gitlab.com/apparmor/apparmor/-/blob/37cac653d115b9d16afe89188b6872af55dd75b8/profiles/apparmor/profiles/extras/bwrap-userns-restrict

this value has no method ssl

Built without ssl.

opam install ssl.
opam install tls for alternative library, but you should also change your script.

Undefined variable ladspa

Built without ladspa. opam install ladspa.

Unsupported format: %mp3

Built without mp3 encoder.

Encode using %ffmpeg.
opam install lame.
