Here's a link which explains about Changing file permission (and ownership)

If you want to skip these (for now of course), you can create a directory/folder in your user-home directory and work on your C programmes (or others) there.

You can open the terminal (press Ctrl + Alt + T) and cd to the target directory:

cd /path/to/target

To give the file "the_file_name" execute permission (if the file-system allows you with the RW rights):

chmod +x the_file_name

Use a separate file in /etc/apt/sources.list.d/ which contains the deb instruction you're saying now. You'd still need to use sudo, though, to edit / create the file.

A solution would be to do sudo su -c "echo 'deb http://www.duinsoft.nl/pkg debs all' >> /etc/apt/sources.list", which tells the system to run that as superuser, which you get access to by using 'sudo' in front of the 'su' command.

PLEASE NOTE that the `su` command used outside of the command I stated here is dangerous, so you should only use this method if you absolutely need it. Therefore, consider using Solution #3 here instead.

Safest Solution (#3): Use `echo | sudo tee` AND a separate `.list`

You can achieve the same as the above, however, without ever dropping to a superuser prompt though. With this command:

echo 'deb http://www.duinsoft.nl/pkg debs all' | sudo tee -a /etc/apt/sources.list

However, let's also take into account #1 above, and instead use a new file for it:

sudo touch /etc/apt/sources.list.d/duinsoft.list
echo 'deb http://www.duinsoft.nl/pkg debs all' | sudo tee -a /etc/apt/sources.list.d/duinsoft.list

This way, we leave the main sources.list alone, but the sources will be added via an included file that specifically handles this repository. (This is how PPAs get added, by the way!)
