I have now discovered to my surprise that this app called tesseract is a game and has nothing to do with the OCR app.It is, however, confusingly, in the OpenSuse:Leap:15.5 repository. I installed it erroneously (what foolishness!!) after the above-mentioned error had appeared thinking that the error had originated from an incomplete tesseract installation, but have now deleted it from my installation.

This tesseract-ocr version seems to be incompatible with the installed/available version of gimagereader, leading to the error message of my original post.
a) I cannot find it in the OpenSuse repos for 15.5
b) Do you know of a trustworthy provider of the package? (With a simple installation procedure, that doesn’t need a lot of additional prerequisites, including my own knowledge!)
c) Is there a good (linux) alternative for OCR ?
