I use Ubuntu 18.04, and I want to find an OCR programme to use with my scanner. Research showed me that Tesseract was the most usual choice,
so I found and followed several different installation procedures,
none of which gave me a working OCR program. Further research showed
that there are several known problems with this, and no two people
seemed to have the same problem or fix. Eventually I gave up, having
wasted hours getting nowhere.
So I am looking for either a definitive way to get this working, or
more likely, an alternative OCR program.
The destination will usually be LibreOffice Write.
Advice or helpful suggestions welcome, please.

I can only assume that nobody uses OCR on Ubuntu. Oh well.

Have you looked at Vuescan? Its not FOSS, but it should work with
most SANE-compatible scanners and says it does OCR.
I've used it for slide scanning (Fedora Linux, Minolta Scan Dual IV)
and it did what I wanted it to do. The program was straight forward
to use.

No, but I'll take a look. Thanks.

OCRmypdf works and comes with a working Dockerhub image. It is based
on Tesseract.
<https://hub.docker.com/r/jbarlow83/ocrmypdf/>
I've been meaning into set it up as a service on a shared folder,
where my scanner depositing scans. The OCR worked ok, but I had a bit
of trouble determining an event handler for when the scanner PDF file
writing was actually completed. I had a few problems a few months
ago, and gave up, but some of them seem to have resolved themselves,
so I'll give it another go.

OK. I just looked. I'm actually building my own Docker Image (presumably because I wanted to use it on a rPi). It's very simple Dockerfile
---
FROM ubuntu:latest
RUN apt-get update && apt-get install -y --no-install-recommends \
python3 \
python3-pip \
ocrmypdf
RUN pip3 install --no-cache-dir \
watchdog==0.10.2
COPY watcher.py .
ENTRYPOINT ["/usr/bin/ocrmypdf"]
---
I can't speak to your set up, but "apt install ocrmypdf" includes
Tesseract. The Dockerfile is basically doing the ocrmypdf install on
virgin Ubuntu:20.04. It works, I just tested it.

Now working on a Raspberry Pi.
I can store a PDF scan direct to a network share from the Scanner
console, no PC needed.
I have OcrMyPDF running in a Docker container on the rPi, watching
the folder. This automatically adds OCR text to the PDF and moves it
to an appropriate folder.
Now all I need to do is write something to give the scans appropriate filenames, inferred from the OCR text.
Little things please little minds :-)
You are working at the extreme edge of my programming knowledge, so if
I try this, I might get lost!
