Cannot find texlive-lang-dutch (and many others) in apt

I am trying to install the ‘texlive-lang-dutch’ package on my Kubuntu machine. I tried:

sudo apt install texlive-lang-dutch

But this doesn’t work. Obviously, the package is not available:

Unable to locate package texlive-lang-dutch

Indeed, I checked which language packages are available:

texlive-lang-african      texlive-lang-chinese      texlive-lang-czechslovak  texlive-lang-french       texlive-lang-indic        texlive-lang-korean       texlive-lang-portuguese   
texlive-lang-all          texlive-lang-cjk          texlive-lang-english      texlive-lang-german       texlive-lang-italian      texlive-lang-other        texlive-lang-spanish      
texlive-lang-arabic       texlive-lang-cyrillic     texlive-lang-european     texlive-lang-greek        texlive-lang-japanese     texlive-lang-polish   

It is obvious that many language packages are missing, not just dutch. I tried searching for a solution. So far I have tried

sudo apt clean all
sudo apt upgrade

and

sudo apt clean all
sudo apt update
sudo apt upgrade

This doesn’t help. Does anyone know how to solve this issue?
