ocrfeeder is an Ubuntu desktop application which utilises Tesseract and other OCR engines to perform OCR. I had it running OK under Ubuntu 14 but am having problems installing it under 18.04. Problem is unmet dependencies for Python components.
Python version
2.7.15~rc1-1
Specific error message
The following packages have unmet dependencies.
ocrfeeder : Depends: python-sane but it is not going to be installed
Further investigation
I individually installed all the dependent packages for python-sane based on the documentation at https://packages.ubuntu.com/bionic/python-sane. These all installed OK except for python-numpy which gave the error message:
The following packages have unmet dependencies.
python-numpy : Depends: liblapack3 but it is not going to be installed or liblapack.so.3
Installing liblapack3 gave the error:
The following packages have unmet dependencies.
liblapack3 : Depends: libgfortran4 (>= 7) but it is not going to be installed
Installing libgfortran4 gave the error:
The following packages have unmet dependencies.
libgfortran4 : Depends: gcc-7-base (= 7.3.0-16ubuntu3) but 7.5.0-3ubuntu1~18.04 is to be installed
Any idea how to resolve this?
sudo apt update
andsudo apt upgrade
. 2) Please show us the complete output ofsudo apt install ocrfeeder
