Some time ago I've completely moved to Linux (Ubuntu-based Pop_OS!). Now I have more than 500 scanned pages/images of a book which I'm going to convert to an epub. Unfortunately, ABBYY ceased any support for Linux, with Fine Reader being Windows compatible only.

No worries on the "back-end" side, since I can still use Calibre or Sigil, which support Linux out of the box... I heard about Tesseract but would like to hear from veteran book developers if they really recommend it, or is it about a typical 'beggars can't be choosers' sort of thing?
So, any tips, advice on alternative Linux-compatible OCR software that you would
recommend to accomplish the task?
Thank you!
