GUI works, command line fails

[endo32]

Hi,

I have been successfully using the GUI version of Calibre on my windows computer and am able to download the Wall Street Journal as well as other newspapers daily. Works great, however I'd like to move it to my linux NAS that is on all the time.

Every newspaper downloads correctly using the ebook-convert command line utility except the Wall Street Journal. I'm only using the built-in recipes... nothing custom. I have tried troubleshooting but I just can't seem to find the issue. Any assistance you can provide would be appreciated!

This error occurred with 64-bit versions 2.85.1 and 3.0.0.

Command:

/opt/calibre/ebook-convert "The Wall Street Journal.recipe" /srv/dev-disk-by-label-Share4/calibre-downloads/wsj.azw3 --username="blah@gmail.com" --password "123" --output-profile kindle_voyage

The error message is below (using full verbosity):

The GUI and the command line use exactly the same code to download recipes. In fact the GUI runs a background worker process to do the actual download. You are specifying the username and password correctly? If they have special characters remember to enclose them in quotes.
