    sources.list modification question

    While I think I understand the reason my current ("stock") sources.list is laid out the way it is -and- I think I understand that my proposed modification will be acceptable, I ask first mainly to reduce potential variables in the beta test and secondly for my own edification.

    The first list is my proposed mod and the second what came with the install. Is the first functionally the same as the second? If so, would it be any faster to download updates?


    # Proposed sources.list:
    deb http://us.archive.ubuntu.com/ubuntu/ lucid main restricted universe multiverse
    deb-src http://us.archive.ubuntu.com/ubuntu/ lucid main restricted universe multiverse

    Finally, what could I expect from the following?

    Many thanks!

    Re: sources.list modification question

    Since no one seems to want to reply ...
    ... I'll do it myself.

    The answer is that neither one is functionally different (unless I mistyped).

    I guess I have never paid close attention to the relationship between what is in the sources.list and what rolls by on the screen and seeing the individual items (main restricted etc.) resolved separately. Why that is I cannot say.

      I ask because you've got the sources enabled.
      Sources were (and often are) enabled by default and I never quite understood why, to be honest.

      Often, I will hack my sources.list to include repos that are turned off (e.g. backports) or missing (e.g. opera) and turn sources off. But since this is beta I have left them on in a quasi-blind state of ignorance. Although it's been awhile since I've done beta testing this is the first time I've beta tested a distro. Initially my thinking was that it might be useful somehow in troubleshooting (ala "debug" mode) and so I've not modified my sources.list (thought about it, obviously). As I think about it more, I don't suppose that there is even a real need for me to have the source unless I run into a problem that would require it and even then it wouldn't be hard to remove and (re)install to get the src.

      I have not compiled applications in quite a few years and even then it was rare. I've compiled a driver or two, most notably the Broadcom STA driver for my PCMCIA card which, by the way, I am not including in the beta testing -- hardwired broadband only at this point. But until recently, that's the only impetus I have had to compile my own. However, I am doing the front end work to do some kernel hacking in the not too distant future but I am starting to deviate from the thread with that one.

      I'll wait a while to be sure no one sees a reason not too but will eventually turn src off here as well.

        In Lucid there are no backports yet anyway, not until work is done on 10.10 to actually backport from

        I would go with the defaults that you find in KPAckagekit's software sources config area, and go from there. Unchecking the Sources option will basically just speed up downloading the updates lists. From there you can also enable the Partner repo as well.

        No need to muck about with the sources.list file as much these days

          OK, thanks. Did both. But I'm basically a command line junky so it may take me a while to break that habit.
