  • Bug#1108949: utrans-rc: installing utrans-rc generates a /etc/init.d/ex

    From Lucas Nussbaum@21:1/5 to All on Tue Jul 8 14:10:01 2025
    Package: utrans-rc
    Version: 0.7-1
    Severity: serious

    If I install utrans-rc, it generates a /etc/init.d/exim4 file, which
    conflicts with the file installed by the exim4-base
    package.

    This results in this prompt when installing exim4-base.

    Configuration file '/etc/init.d/exim4'
    File on system created by you or by a script.
    File also in package provided by package maintainer.
    What would you like to do about it ? Your options are:
    Y or I : install the package maintainer's version
    N or O : keep your currently-installed version
    D : show the differences between the versions
    Z : start a shell to examine the situation
    The default action is to keep your current version.
    *** exim4 (Y/I/N/O/D/Z) [default=N] ?

    I suppose that this happens if exim4-base is unpacked but not configured
    before utrans-rc is configured, but I'm not sure.

    Thanks. I am away until Thursday, but will look then.

    Maybe the postinst should use the trigger so it happens after all
    packages are installed and configured.

    Lucas,

    Thanks for this. I am afraid I am unable to reproduce.

    There might be a potential issue in that /etc/init.d/exim is in exim4-base whereas /usr/lib/systemd/system/exim4.service is in exim4-daemon-light.

    Having said that, I cannot generate a failure by installing utrans-rc and exim4-base or exim4-daemon-light. It would seem that your error is caused by utrans-rc producing /etc/init.d/exim4 from /usr/lib/systemd/system/exim4.service
    before exim4-base is installed. But exim4-daemon-light depends on exim4-base, so
    I don't currently see how that can happen.

    Do you have a reliable reproducer?

    Thanks

    Mark

    Thanks. I suggest the following patch. It fixes the mmdebstrap reroducer for me.

    utrans-rc.postinst: use manual trigger to regenerate scripts so it happens after all other packages are configured.
