I recently updated TeX Live to following version
TeX 3.1415926 (TeX Live 2013/Arch Linux)
and cannot compile any file anymore, it fails with error
$ pdflatex blab.tex This is pdfTeX, Version 3.1415926-2.5-1.40.14 (TeX Live 2013/Arch Linux) restricted \write18 enabled. ---! /var/lib/texmf/web2c/pdftex/pdflatex.fmt doesn't match pdftex.pool (Fatal format file error; I'm stymied)
After some research, I found out I am supposed to run
fmtutil --all, but it also fails with error
$ fmtutil --all /usr/bin/fmtutil: line 395: /usr/share/texmf/texconfig/tcfmgr: No such file or directory fmtutil: config file `fmtutil.cnf' not found.
I tried some fixing to no avail:
texconfig rehash do not change anything, and
kpsewhich fmtutil.cnf yields
/etc/texmf/web2c/fmtutil.cnf, as it is apparently supposed to.
