Package installation instructions for Ubuntu Linux are not working with sudo

[Tvangeste]

Please be informed that the package installation instructions for the Ubuntu Linux do not work with sudo:

sudo echo 'deb http://download.opensuse.org/repositories/home:Tvangeste/xUbuntu_13.04/ /' >> /etc/apt/sources.list.d/goldendict.list
bash: /etc/apt/sources.list.d/goldendict.list: Permission denied

Even though they don't mention 'sudo', a typical user would invoke them with sudo, and will fail. I had this problem, and some users have it as well. For example:

Maybe it makes sense to add some info about sudo to the instructions? Here's the correct sudo command that works:

sudo sh -c "echo 'deb http://download.opensuse.org/repositories/home:Tvangeste/xUbuntu_13.04/ /' >> /etc/apt/sources.list.d/goldendict.list"

As an alternative, the following instruction text might be changed:

For xUbuntu XX.XX run the following as root:

To:

For xUbuntu XX.XX run the following as root (invoke sudo -s to obtain the root shell):
