I use Tex and Latex on Debian (Windows Linux Subsystem). I first intalled the tex_base Debian package, and also latex_base package, with apt-get. I think Debian uses Tex 2018. Then I install additional packages with TLmgr, Tex own package manager. I had to change year to 2018 in Tlmgr. I do it this way to have a minimal Tex/Latex install so not to take up too much disk space. Up until now I have managed to install new packages from ctan every time my document asks for more. However, now I get the error
! Undefined control sequence. \LaTeX3 error: Use \cs_prefix_spec:N not \token_get_prefix_spec:... l.9 \begin{document} ?
Is it at all possible to fix this? What file do I need to edit? Some times Tlmgr can not find the package. So I find it manually on ctan or tug and copy it manually to my user latex directory. I think some of these standalone packages are from 2020 or 2021. This could be the root of this error. Maybe they are noe compatible? I have read this one but did not find my solution. And also this one.
