Subject: bug#52305: calibre unable to fetch news

From: rdes <[email-masked]>
Date: Sun, 05 Dec 2021 13:24:31 +0000

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".
