Root CA Zertifikat importieren
Entsprechend der Beschreibung hier müssen folgende Punkte ausgeführt werden.
Given a CA certificate file foo.crt, follow these steps to install it on Ubuntu:
1. Create a directory for extra CA certificates in /usr/share/ca-certificates:
sudo mkdir /usr/share/ca-certificates/extra
2. Copy the CA .crt file to this directory:
sudo cp foo.crt /usr/share/ca-certificates/extra/foo.crt
3. Let Ubuntu add the .crt file's path relative to /usr/share/ca-certificates to /etc/ca-certificates.conf:
sudo dpkg-reconfigure ca-certificates
- To do this non-interactively, run:
sudo update-ca-certificates
In case of a .pem file on Ubuntu, it must first be converted to a .crt file:
openssl x509 -in foo.pem -inform PEM -out foo.crt
