When I install an application the software center does not respect the system language (in my case LibreOffice), an expert user who knows how to do it, type: "sudo apt install libreoffice-l10n-it" and has the language in Italian or other language, but an impractical user (who is the user to whom a software center is addressed) finds himself with the language in English. I'm reporting this bug because a user on a forum complained about LibreOffice that is not installed with the system language, but it is in English, and because the same thing happened to me from plasma discover, I had to install the language from the terminal. can you do something about it? (I hope I explained myself well, because I'm writing with google translator)
I'm aware of this issue, this is not something I can do much about. I opened a bug in appstream, maybe we can do something about it: https://github.com/ximion/appstream/issues/191
