I cleared out the course's tmp folder, tried to create a hardcopy, got the errors, and noticed two (?) directories showed up in the tmp folder.
Then I did this
in each directory and got an .aux and a .log file in each. The .aux files didn't say much besides \relax and a few \newlabel{tocindent-1}{0pt}, etc., but the .log files gave messages about fonts. Here are the .log files (I changed extension to .txt since my faculty webspace ignores .log):
http://faculty.elac.edu/manriquem/upload/hardcopy1.txt
http://faculty.elac.edu/manriquem/upload/hardcopy2.txt
So should I install the texlive-full Ubuntu package? Or something else?
Thanks. Miguel
