Several things are wrong here.

The log shows you importing a book in KF8 format, not KFX, so it has nothing to do with this plugin.

Even if the book was in KFX format, this plugin has nothing to do with DRM removal.

Providing help with DRM removal is not allowed on MobileRead. You need to ask for help at the website where you obtained the DRM removal plugin, Apprentice Alf's Blog or Apprentice Harper's GitHub.

After updating calibere the plugins seem to have been removed and i can no longer remove DRM. Help?

What version of calibre were you on, and what did you upgrade to?

Start calibre in debug mode and post the startup log

If you updated to calibre 5 from a version before that then some of your plugins may be incompatible and also need to be updated. If the KFX Input plugin appears to be missing then I recommend that you download the latest version from the first post in this thread and install it.

For help with DRM removal and the associated plugin ask for help at either Apprentice Alf's Blog or Apprentice Harper's GitHub.

Sorry for the delay. I was on vacation and am getting caught up.

This is the thread for the KFX Input plugin which is not involved in this error. I see that you have also posted in correct, KFX Output plugin thread, so I will respond there.

Is there a source for information on the KPF file format, as generated by Kindle Create (instead of downloads from Amazon) ? I am trying to create .kpf files from PDF using a Linux workflow -- instead of having to insert the PDF into a Windows or Mac interactive application.

The only aspect of KPF that Amazon has documented is the Ion format in which much of the content is encoded. Documentation for that is here: Amazon Ion. However that is only one small part of KPF. There is no actual documentation of KPF format as far as I know.

I was able to reverse engineer the format enough to write my KFX Input and Output plugins mostly by trial and error. However I don't know anywhere close to enough about it to generate a KPF file except by using the Amazon applications that can produce it, Kindle Create and Kindle Previewer.

The Kindle Previewer has a command-line interface that can be invoked by other programs to produce KPF files. It is documented in the Kindle Previewer User Guide. That is what my KFX Output plugin uses to produce KPF. But that only works for reflowable books based on either EPUB or MS Word as a source format. There is no provision for generating Fixed Layout KPF based on PDF.
