Remove the slide count from Beamer footer

Question

I would like to remove the slide count (e.g., SLIDE_NUMBER / TOTAL_SLIDES) from the footer (footline) of a Beamer presentation, without removing the footer entirely. I am using the Boadilla theme, which uses the infolines outer theme. In the beamerouterthemeinfolines.sty file, we find the following definition for the footline:

\defbeamertemplate*{footline}{infolines theme}
{
  \leavevmode%
  \hbox{%
  \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{author in head/foot}%
\usebeamerfont{author in head/foot}\insertshortauthor~~(\insertshortinstitute)
  \end{beamercolorbox}%
  \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{title in head/foot}%
\usebeamerfont{title in head/foot}\insertshorttitle
  \end{beamercolorbox}%
  \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,right]{date in head/foot}%
\usebeamerfont{date in head/foot}\insertshortdate{}\hspace*{2em}
\insertframenumber{} / \inserttotalframenumber\hspace*{2ex} 
  \end{beamercolorbox}}%
  \vskip0pt%
}

I need to essentially redefine this outer theme such that it doesn't have the \insertframenumber{} / \inserttotalframenumber\hspace*{2ex} in it, or otherwise define a new outer theme that inherits everything else from the infolines theme. How can I do this?

Answer 1

As beameroutertheminfolines.sty has changed since 2010, for now it's enough to put

\setbeamertemplate{page number in head/foot}{}

in preamble.
