  • Bug#1109132: sbuild: document how to use an apt proxy

    From Lucas Nussbaum@21:1/5 to All on Sat Jul 12 09:20:02 2025
    Package: sbuild
    Version: 0.89.3
    Severity: wishlist

    Hi,

    While refreshing my sbuild setup, I failed to find documentation on how
    to use an APT proxy together with unshare+mmdebstrap.

    Ideally there would be doc about:
    - specifying an APT proxy by URL
    - using auto-apt-proxy to auto-detect the proxy

    And it should be documented how to do that using command-line options,
    and in .config/sbuild/config.pl

    Regarding config.pl, maybe it can be solved by improving the example
    config.pl

    It looks like the following does what I need:
    $piuparts_opts = ['--bootstrapcmd=mmdebstrap --skip=check/empty --variant=minbase --include=auto-apt-proxy', '--no-eatmydata', '--distribution=%r', '--fake-essential-packages=systemd-sysv'];
    $unshare_mmdebstrap_extra_args = [
    "*" => ['--include=auto-apt-proxy']
    ];

    Best,

    Lucas

    I think there is agreement that these common usecases should be
    documented in the manual pages, but it has not happened yet.

    For "APT proxy by URL", the config.pl fragment that currently gets advertised is:

    push @{$unshare_mmdebstrap_extra_args}, "*",
    ['--aptopt=Acquire::http { Proxy "http://127.0.0.1:3142"; }'];


    Hope this helps,
    Chris

    That is correct. I'm working on it. Sorry for the delay. I'm not at DebConf because these weeks it's exam season so I'm very busy... :(

    Thanks!

    cheers, josch
