installation 2.7 sur Ubuntu problème compilation

[rawfiner]

Oui, je suis reparti de zéro.
Par contre, j'ai mon vieux PCque j'ai ressuscité avec Lubuntu 18.04 LTS, qui me sert de banc d'essai. J'ai donc essayé de ce fait là aussi et encore une autre bizarrerie de docker. Tout commence bien et avant de commencer la complation, il ne trouve pas un fichier "/usr/lib/llvm-9/bin/lit-cpuid".
J'ai donc regardé et pas trouvé llvm-9 à l'endroit indiqué. Est-ce un pb de lubuntu par rapport à Ubuntu?

Code :

root@f2b8d05b4d38:~/darktable# CC=gcc-9 CXX=g++-9 ./build.sh --install
Darktable build script

C'est deux pb différents me semble-t-il, mais si on résoud le pb Ubuntu, va-t-on avoir le même pb que lubuntu???
J'essaie de voir avec synaptic pour connecter le "démon" avec docker et continuer à avancer.

Alors ça, aucune idée...
