Impossible de localiser le paquet libgstreamer0.10-dev sur Ubuntu 18.04

J'essaie d'installer OpenCV4 comme expliqué ici: https://www.learnopencv.com/install-opencv-4-on-ubuntu-16-04/

Quand j'arrive à

Sudo apt -y install libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev

Je reçois

Reading package lists... Done

J'ai vérifié en ligne et les packages sont disponibles sur https://packages.ubuntu.com/search?keywords=libgstreamer0.10-dev

J'ai essayé de télécharger et d'installer manuellement avec

Sudo apt install ./libgstreamer0.10-dev_0.10.36-1.5ubuntu1_AMD64.deb

Ce qui me donne

Note, selecting 'libgstreamer0.10-dev' instead of './libgstreamer0.10-dev_0.10.36-1.5ubuntu1_AMD64.deb'
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libgstreamer0.10-dev : Depends: libgstreamer0.10-0 (= 0.10.36-1.5ubuntu1) but it is not installable
                        Depends: libglib2.0-dev but it is not installable
                        Depends: libxml2-dev but it is not installable
                        Depends: gir1.2-gstreamer-0.10 (= 0.10.36-1.5ubuntu1) but it is not installable
E: Unable to correct problems, you have held broken packages.

Je suis nouveau sur Ubuntu (utilisé uniquement Manjaro). Je ne comprends pas pourquoi apt ne peut pas localiser un paquet s'il se trouve sur le site Web.

libgstreamer0.10-dev est obsolète dans Ubuntu 18.04.

Donc, utilisez plutôt une version plus récente:

Sudo apt install -y libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev

Cela fonctionnera sûrement.

Je suis stupide. Trouvé le même guide pour Ubuntu 18.04: https://www.learnopencv.com/install-opencv-4-on-ubuntu-18-04/
