I am installing Roundcubemail on CentOS7-arm

roundcubemail-1.1.8-1.el7.noarch

The installer web app creates a config.inc.php to save within the
/etc/roundcubemail/ directory. It warns that:

“Make sure that there are no characters outside the brackets when saving the file.”

Thing is there is no ?> at the end of this. It is left out. So I got to add that myself. I should be able to just copy the content of the text box, and paste it into a cat > /etc/roundcubemail/config.inc.php, but I am left having to at least having to add the ending ?>
