Hi

sorry for the vacation-induced delay. If you haven't figured it out yet,
here's some hints:

This creates a node with the label 'last()+1' - the first argument to
ins is taken verbatim. Since the entries in sources.list are numbered 1,
2, 3, etc. you should insert new ones as 01, 02, etc.

There's a couple problems here: (1) the entries are not in the necessary
order (order matters with Augeas' tree) (2) you have an extra '"' after
uri.

You can always get more information about errors with
'print /augeas//error' - if that prints nothing, there were no errors.

These commands do what you want them to do:

        ins 01 after /files/etc/apt/sources.list/*[last()]
        set /files/etc/apt/sources.list/*[last()]/type deb
        set /files/etc/apt/sources.list/*[last()]/uri "http://mirror.switch.ch/ftp/mirror/debian/neu"
        set /files/etc/apt/sources.list/*[last()]/distribution experimental
        set /files/etc/apt/sources.list/*[last()]/component main
        print /files/etc/apt/sources.list/*[last()]
        save
        print /augeas//error
