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

I confirm the bug also on Ubuntu 19.04.
Patch on post #3 resolve the problem.

Nowadays on laptop we have more and more 4K screen, the default font in TTY framebuffer is very too small. For people who have Xorg no starting, TTY is unique path to fix configuration.
