No plugin to handle input format: doc - Calibre

Asked by Abs

I am trying to convert a doc to an epub using calibre via the command line but I get this error.

Traceback (most recent call last):
  File "site.py", line 61, in main
  File "site-packages/calibre/ebooks/conversion/cli.py", line 341, in main
  File "site-packages/calibre/ebooks/conversion/cli.py", line 300, in create_option_parser
  File "site-packages/calibre/ebooks/conversion/plumber.py", line 734, in __init__
ValueError: No plugin to handle input format: doc
I haven't been able to find any answers or documentation about this. Any help appreciated.

I am using shell_exec to run this command via PHP.

Saucy is EOL and no longer supported in any way. I suggest you upgrade to Trusty which is LTS and supported til April 2019

Can you help with this problem?
