    Wrong copy-paste (to match what is given below), but this is the

    while this is a valid package name: with an "apt" command, I get:

    libnsl-dev libnsl-dev:i386 libnsl2:i386 libtirpc-dev libtirpc-dev:i386

    libtirpc3:i386
    [...]

    The package name is listed above.

    Package: dpkg
    Version: 1.22.5
    Severity: important

    I get the following error:

    cventin:~> dpkg -s libc6-dev
    dpkg-query: error: --status needs a valid package name but 'libc6-dev' is not: ambiguous package name 'libc6-dev' with more than one installed instance

    while this is a valid package name: with an "apt" command, I get:

    The following packages were automatically installed and are no longer required:

    ^^^^^^^^^^
    libtirpc3:i386
    [...]

    The package name is listed above.

    "apt-cache show libc6-dev" also lists this package.

    apt behaves differently, this has been also a known discrepancy, but
    then they operate in general differently when it comes to their CLI
    arguments anyway.

    The difference is bad for the user, making simple copy-paste
    impossible, and usage more difficult: the user doesn't know
    in advance whether the package name given by apt needs to be
    completed for dpkg (systematically adding the main architecture
    does not work for "Architecture: all" packages).

    That's why dpkg is and has always been internally consistent, and
    always arch-qualifies Multi-Arch:any packages (and more recently also
    foreign arch:any packages), so that its output can always be used as
    its input, even during a cross-upgrade of dpkg itself. As mentioned
    above, it's unfortunate that apt implemented a different interface.

    Thanks,
    Guillem
