Analysis:

For 1) chromium: it is likely an oversight that the chromium web browser users/ducumentation so often refers to as 'chromium' is in the Ubuntu repos as 'chromium-browser'. However, a user might confusingly get the below output when trying to install the suggested chromium package:

    $ sudo apt-get install chromium
    Reading package lists... Done
    Building dependency tree
    Reading state information... Done
    Package chromium is not available, but is referred to by another package.
    This may mean that the package is missing, has been obsoleted, or is only available from another source
    However the following packages replace it:
    chromium-bsu

    E: Package 'chromium' has no installation candidate
    ---

    Installing chromium-bsu will work but leaves the user with an unrelated package installed...

For 2) hal we have a similar situation:

    $ sudo apt-get install hal
    Reading package lists... Done
    Building dependency tree
    Reading state information... Done
    Package hal is not available, but is referred to by another package.
    This may mean that the package is missing, has been obsoleted, or
    is only available from another source
    However the following packages replace it:
    hal-info

    E: Package 'hal' has no installation candidate
    ---

    Installing hal-info will work but leaves the user with an unrelated package installed...

A simple change to the pepperflashplugin-nonfree 'suggests' entree can correct both situations.
