I recently updated my operating system from Ubuntu 13.04 to Ubuntu 13.10.
Since then, I am facing difficulties compiling my TeX code in which the french babel package is called. Please note that all my sources were compiling very fine before the system upgrade.
However, now, given the following header:
\usepackage[francais]{babel}
I receive the following error:
! Package babel Error: Unknown option `francais'. Either you misspelled it
What should I do? Please note that if I remove this part of code (\usepackage[francais]{babel}), everything is compiling well. I also tried it with french, and I receive the same result.
Thank you in advance for your help.
MINIMUM WORKING EXAMPLE :
\documentclass[11pt,a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage[francais]{babel}
\usepackage[T1]{fontenc}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\begin{document}
This is a MINIMUM WORKING EXAMPLE.

! Package babel Error: Unknow option `francais'. Either you misspelled it

I receive the same error. – Martingal Oct 20 '13 at 13:41frenchoption, and add all your preamble for us to see if there is some problems in it. – Ludovic C.

If I remove it, there is no further error. – Martingal Oct 20 '13 at 13:49frenchb.frenchandfrancaisare both aliases of this name. A few years ago there used to be an autonomousfrenchpackage which did a similar job and could be used withbabel. (This package still exists under the nameeFrenchafter having been a shareware namedFrenchProfor a while). hence possible confusions and the choice offrenchbfor the french option of babel. In recent distributions however, the namesfrenchb,frenchandfrancaisas options for babel should lead to the same results. – Franck Pastor Feb 05 '14 at 14:11
