Hello Augustin,
it seems like there is no action on this bug report, unfortunately.

So I followed the instructions in #1137654. For the record, the public
key for verification can be found here:
https://developers.hp.com/hp-linux-imaging-and-printing/hplipDigitalCertificate.html

To install the plugin, I did *not* call hp-plugin. As already
discovered in #1137654 this fails.

Instead I obtained "hplip-3.26.4-plugin.run". As I was able to verify
the authenticity with the key obtained above, I executed it (as
non-root!) and it installed the plugin without problem.

And now scanning works again!

I CC'ed 1137654, as this might make printer installation possible as
well.

That would be perfect! Using #1137654 with my instructions above
hopefully make this possible.

Greetings
