Ubuntu TrueType fonts installation helper for Fedora 15 Lovelock (and above)

This page provides a bash script for an easier installation of the Ubuntu TrueType fonts. I think it is useful because there is only a ubuntu-title-fonts package included in the main repositories right now. See the main article for details:

Open a terminal and run the following commands to download and execute it (copy and paste recommended):

wget "http://blog.andreas-haerter.com/_export/code/2011/07/18/install-ubuntufonts-fedora.sh?codeblock=1" -O "/tmp/install-ubuntufonts-fedora.sh"
chmod a+rx "/tmp/install-ubuntufonts-fedora.sh"
su -c "/tmp/install-ubuntufonts-fedora.sh"
install-ubuntufonts-fedora.sh
#!/bin/bash

# Ubuntu fonts installation helper for Fedora Linux
#
# This script is installing the fonts without any untrustworthy RPMs or build-
# hazzle. I think it is useful because there is only a "ubuntu-title-fonts"
# package included in the main repositories right now.
# Please note that the yum/RPM database is bypassed, so you can't uninstall
# the fonts by using yum erase/remove.
#
# Tested on the following Fedora versions:
# - Fedora 15 Lovelock
#
# I don't have the time to test *every* version out there. Therefore it does not
# mean that this script does not work if your version is not listed above. Just
# try it out and check for an update of this script after a new version of
# Fedora is released:
# <http://blog.andreas-haerter.com/2011/07/18/install-ubuntufonts-fedora.sh>
#
# Usage:
# 1) Call this script with SUPERUSER privileges (->su -c, sudo ...)
# 2) If something fails, correct the thing which prevents the successful
#    execution and call it again. This script is designed in a way that
#    re-calling it should be no problem.
#
# Please note that the yum/RPM database is bypassed, so you can't uninstall
# the fonts by using "yum erase/remove". But you may run the following commands
# to get rid of the fonts:
# 1) su -c 'rm -rf "/usr/share/fonts/ubuntu/"'
# 2) fc-cache -fv
#
# Please read the UBUNTU FONT LICENCE (<http://bit.ly/ajeQvv>) for all the rules
# that govern the use of the fonts.
