After updating Eclipse Photon to 2018-09, the startup shows a screen for requirements update (attached: Req.png).

When accepting the update, Oomph shows an error (Fail.png).

Any pointers to correct the situation?

Yes, unfortunately the Photon installation created with the Photon installer really wants to be a Photon installation so if you manually update it, it will complain that it's no longer Photon with this rather user-unfriendly overly-technical dialog. You could tell it to "Skip" and to "Remember my decision" to keep your manual updates as is. If you let it "perform" it will try to downgrade your installation back to Photon, which is unlikely to be what you want (and apparently fails in your case).

At EclipseCon I discussed this with other folks at the Planning Council and I think it will be better if the product catalog is generated so that the upper bounds are removed from the requirements such that this dialog will not appear when you manually update.

Thanks.

If I jettison the installation after saving the selections to a p2f file, and installing the 2018-09 release with the installer, then reloading all plugins from the p2f file, will it then be happy?

Yes.

Though Oomph as bunch of useful features that would make this all easier to do automatically.

https://wiki.eclipse.org/Eclipse_Oomph_Authoring

For example you could use Navigate -> Open Setup -> Installation, then double click the Installation object to bring up the Properties view and edit the Product Version to choose a newer version of the same product you already installer. You might pick the 2018-09 version, or Latest Released version so that the installation will automatically update when there is a new release. After saving this, you can do Help -> Perform Setup Tasks to do your update (or to check for updates in general).

If there are things you always install, you can create a p2 task for that in your user.setup, using Navigate -> Open Setup -> User to do that. E.g., I have this in my user.setup so that I always install vi plugin when I create a new installation with the installer.

<?xml version="1.0" encoding="UTF-8"?>
<setup.p2:P2Task
    xmi:version="2.0"
    xmlns:xmi="http://www.omg.org/XMI"
    xmlns:setup.p2="http://www.eclipse.org/oomph/setup/p2/1.0"
    label="VI">
  <requirement
      name="com.mbartl.viplugin.eclipse.feature.group"
      optional="true"/>
  <repository
      url="http://viplugin.com"/>
</setup.p2:P2Task>

Of course Oomph can also automatically clone the projects on which you work, import them into your workspace, and organize them into working sets so that you never need to manually setup an IDE and can instead create a fresh new properly installed, properly configured installation and workspace easily and automatically.
