I updated my operating system on my laptop from Ubuntu 12.04 to 14.04 yesterday, and now I cannot compile my .tex files. I always get the following message.
This is pdfTeX, Version 3.1415926-2.5-1.40.14 (TeX Live 2013/Debian)
restricted \write18 enabled.
---! /var/lib/texmf/web2c/pdftex/latex.fmt doesn't match pdftex.pool
(Fatal format file error; I'm stymied)
I tried searching for some information and found the suggestions offered here. I tried first running
but that didn't work, so next I tried
sudo fmtutil-sys --all
but that also didn't work. I also found this thread asking essentially the same question, but the focus there seemed to be on having a "portable install." I'm not exactly sure what a portable install is, but I don't think I have that on my laptop so I don't know if the answers on that thread are of any use to me.
