当你在 Ubuntu 盒子上时:

edd@max:~$ locate lmodern.sty                ## look for this file
/usr/share/texmf/tex/latex/lm/lmodern.sty
edd@max:~$ dpkg -S $(locate lmodern.sty)     ## look for package with this file
lmodern: /usr/share/texmf/tex/latex/lm/lmodern.sty
edd@max:~$ 

表示您要安装lmodern软件包:

sudo apt-get install lmodern

您还可以search online at package.Ubuntu.com这也建议使用 lmodern 包。
