I've looked at similar questions without seeing an answer to my situation.
Running TeXLive-20170520 and LyX-2.2.3 on Slackware-14.2.
From CTAN I downloaded the invoice2 package and built it. The files are in ~/documents/LaTeX/invoice2/. A copy was placed in /usr/share/texmf/tex/latex/invoice2/ and texhash was run.
Neither lyx or latex can find invoice2.sty when it's included in the preamble (\usepackage{invoice2}). I cannot find it using kpsewhere (or kpsewhich). What step did I miss?
/usr/share/texmf/tex/latex/invoice2/
seems to be the wrong place. Where is TeX Live 2017 located? Is there atexmf-local
folder somewhere?
