sources line is modified if a complete apt line is given

[Brian Murray]

I was trying to add the oneiric-proposed pocket to my /etc/apt/sources.list with add-apt-repository instead of using vi. I was using the following command:

sudo apt-add-repository "http://archive.ubuntu.com/ubuntu/ oneiric-proposed main universe"

and the following line appeared in my sources.list

deb http://archive.ubuntu.com/ubuntu/ oneiric oneiric-proposed main universe
deb-src http://archive.ubuntu.com/ubuntu/ oneiric oneiric-proposed main universe

Notice that oneiric was added before oneiric-proposed. The documentation for add-apt-repository indicates that:

<sourceline> - The apt repository source line to add. This is one of:
   a complete apt line in quotes,

I did provide a complete apt line and it was modified by apt-add-repository and now I can't run 'apt-get updates'.

A "complete apt line in quotes" requires a type at the beginning, (deb, deb-src, rpm, or rpm-src). If you add "deb " to your example, it will work as you expect. Without a type, it matches this argument type: "a repo url and areas in quotes (areas defaults to 'main')" so oneiric-proposed is assumed to be an area.

@Brian Murray: How would you like apt-add-repository to behave in this case? I tend to agree with Nick Russo, you have not specified a complete apt line in quotes, thus apt-add-repository is behaving as it should and as it is described with the --help option.

I believe that apt-add-repository broke my sources.list file by adding in 'oneiric' instead of using 'oneiric-proposed' as I said. I think it should either add 'deb' and 'deb-src' for me or error out.

[Nick Russo (narusso-u)]

I can only see two resolutions that might satisfy Brian's request:

1) teach apt-add-repository to differentiate between areas and distro names,
2) remove the 2nd sourceline variant described in the documentation.

The 2nd option would break valid existing scripts that use this tool.

The 1st option requires a database of all valid areas and distro names, which seems infeasible.
