On Linux, I've downloaded the "diepen" Beamer theme to my ~/texmf folder. I've run texhash ~/texmf, which happily creates an ls-R file containing this:
% ls-R -- filename database for kpathsea; do not change this line.
./:
.:
beamerthemediepen-master
ls-R
[some lines omitted]
./beamerthemediepen-master/themes/theme:
beamerthemediepen.sty
But if I then run kpsewhich beamerthemediepen.sty, it prints nothing. And, indeed, trying to use \usetheme{diepen} in my Beamer file results in this error message:
File `beamerthemediepen.sty' not found.
What am I missing?
texhash. Unless you've changed the global configuration, no database is needed or used for~/texmf@daleif. – cfr Oct 23 '19 at 15:05
