ca-certificates update
2014-12-11 - Jan Alexander Steffens

The way local CA certificates are handled has changed. If you have added any locally trusted certificates:

Move /usr/local/share/ca-certificates/*.crt to /etc/ca-certificates/trust-source/anchors/
Do the same with all manually-added /etc/ssl/certs/*.pem files and rename them to *.crt
Instead of update-ca-certificates, run trust extract-compat
Also see man 8 update-ca-trust and trust --help.
