pkg-map incompatible with new install-packages element

[Abel Lopez]

The latest update to install-packages I3f182aa3aae0a79b2f3ea4e66c1878ad12878b0a
 takes input from a file in /tmp/package-installs.json

Unfortunately, this includes error messages, like "Missing package name for distro", which package-installs takes literally and errors out as
E: Unable to locate package Missing
E: Unable to locate package package
E: Unable to locate package name
E: Unable to locate package for
E: Unable to locate package distro
E: Unable to locate package ubuntu
install failed with error Reading package lists...

Simply commenting out the setting of the error fixes it, but it would be nice to redirect this output to console and not the file.

    Ignore stderr from pkg-map

    The latest update to package-install captures both stderr and stdout
    from pkg-map, unfortunately, pkg-map has a 'missing-ok' option
    which causes it to print an error message on stderr.
    The result is that package-install tries to look for packages named
    "Missing", "package", "name", etc.

This is reopened, turns out the original patchset fixed the issue properly, but the subsequent suggestions from the community that created patchset 4 doesn't fix the bug

May have spoken too soon,
