Thank you for the tip kovid!
verbose output gives me:
Traceback (most recent call last):
File "/usr/lib/calibre/calibre/web/feeds/recipes/collection.py", line 222, in get_builtin_recipe_by_title

context.load_cert_chain(cert_file, key_file)
SSLError: [SSL] PEM lib (_ssl.c:2525)
seems a certificate problem?
As I got the url in the verbose output I tried:
wget
https://status.calibre-ebook.com/rec...mes_sub.recipe
and it did not work. It says that it doesn't trust the certificate. But the wget command doesn't work on my MINT-Linux either where the update of the recipes works during ebook-convert.
Any hint for whats going on in Rasbian?
