Thanks for the pointer to SSL_CERT_FILE. I have now changed my script to this (without the export step):
Code:
SSL_CERT_FILE=/mnt/onboard/.adds/koreader/common/turbo/ca-certificates.crt /mnt/onboard/wallabako -output "/mnt/onboard/Documents/Wallabag" -delete
This is much better since I was concerned that a software update would remove my link.
If I find the time, I'll try to do a minimalist koreader plugin to just run the script.
Nickel is pretty but KOReader is very powerful. I love the OPDS integration so I can get books from my own server or Feedbooks, ManyBooks... Now with a working Wallabag setup I'm super happy.
I'll open a request on the issue tracker for an option to delete files from the server. It would be a nice-to-have feature but I can live without.
Thank you for Wallabako!
