Language detection for "glossaries" package

I want to use the glossaries-french package, according to the documentation it is in the TEX Live package bundle:

Contained in TEX Live as glossaries-french

And I installed the packages texlive-latex-extra texlive-lang-french in my Ubuntu. So I expect to be able to import it with usepackage{glossaries-french}.

But I face this error message during the compilation :

LaTeX Error: File `glossaries-french.sty’ not found.

Note that I don’t have any error using only usepackage[acronym]{glossaries}.

So I guess that I don’t understand how the LaTeX packages works or I don’t understand the documentation.

Edit

Based on comments I remove the glossaries-french import and I check the babel parameters, and I found what was wrong. But it’s still not the expected behaviour :

documentclass[11pt]{report}
usepackage[utf8]{inputenc}
usepackage[english,french]{babel} % french is the main language
usepackage[acronym]{glossaries}

makeglossaries

newacronym[longplural={réseaux de neurones artificiels}]{rna}{RNA}{réseau de neurones artificiels}

begin{document}
    Test acrfull : acrfull{rna}

    Test acrfullpl : acrfullpl{rna}
end{document}

And if I reverse the languages in the babel parameters I got the expected result (no s at the end of the acronym) :

usepackage[french,english]{babel} % english is the main language
...

The result is all good, but the main language is not french anymore. Based on babel documentation :

In multilingual documents, just use a list of the required languages as package or class options. The last language is considered the main one, activated by default.

Is it a bug or I miss something?

documentclass[fr-CA,11pt]{report}
usepackage[utf8]{inputenc}
usepackage[english,french]{babel} % french is the main language
usepackage[acronym]{glossaries}

makeglossaries

newacronym[longplural={réseaux de neurones artificiels}]{rna}{RNA}{réseau de neurones artificiels}

begin{document}
    Test acrfull : acrfull{rna}

    Test acrfullpl : acrfullpl{rna}
end{document}
