Title:
  FONT="x/y/z" is not applied due to setupcon script bug

Status in console-setup package in Ubuntu:
  Confirmed

Bug description:

  On 18.04 I wanted to set the TTY font to use a Powerline font. Despite
  being able to set the font manually it wasn't being set at boot-time.

  /etc/default/console-setup contains:

  FONT="/usr/local/share/fonts/ter-powerline-v22n.psf.gz"

  "setupcon -v -f" reported an error:

  putfont: KDFONTOP: Invalid argument

  due to passing the font filename twice:

  executing setfont -C /dev/tty1 /usr/local/share/fonts/ter-powerline-
  v22n.psf.gz /usr/local/share/fonts/ter-powerline-v22n.psf.gz.

  The problem is in /bin/setupcon where the collecting variable
  FONTFILES has the font added twice, once at the top of the for loop

  FONTFILES="$FONTFILES `findfile $fontdir $f`"

  and again at the bottom

  FONTFILES="$FONTFILES $RES"

  Removing the first assignment fixes it.

  FONTFILES=''
  echo "DEBUG: FONT=$FONT"
  if [ "$FONT" ]; then
      for f in $FONT; do
        echo "DEBUG: for loop"
          FONTFILES="$FONTFILES `findfile $fontdir $f`"
          RES=`findfile $fontdir $f`
          if [ -z "$RES" ]; then
              fdec="${f%.gz}"
              RES=`findfile $fontdir $fdec`
          fi
          FONTFILES="$FONTFILES $RES"
      done
  fi
  FONTFILES=`echo $FONTFILES` # remove extra spaces
