[Message part 1 (text/plain, inline)]

Hello,

When I click the 'fetch news' button in calibre it always fails to download the news. However, some news sites like kde news and ars technica produce a pdf with the ssl error in it, while fetching cnet will produce a conversion error box with a message "Failed: fetch news from CNET news".

Hi,

I'm trying to reproduce this, but no luck, I'm able to fetch news (cnet
also).

Is it possible that you are testing this in a foreigen environment?
(Is so, you might need to `SSL_CERT_DIR=/etc/ssl/certs calibre` ...)

It appears that calibre does not have SSL_CERT_DIR or SSL_CERT_FILE
(see 'openssl') in its native-search-paths. So I'd suggest adding that,
installing calibre again and logging out and in again (to update the
environment variables).

Greetings,
Maxime
