body: <p>I need to update m4 to <code>1.4.19</code> on Ubuntu <code>18.04</code>, but how to do this ? This is a follow up from <a href="https://stackoverflow.com/a/69195008/1079990">https://stackoverflow.com/a/69195008/1079990</a></p>

  tar -xvzf m4-1.4.19.tar.gz 
  cd m4-1.4.19/ 
  ./configure --prefix=/usr/local/m4 
  make
  sudo make install  # &lt;-- suggested by @git-bruh
  export PATH=/usr/local/m4/bin:$PATH
