Dear openSUSE community, I'm facing issues using self signed certificates on openSUSE Leap 15.3. I have a certificate 'gnuhealth-selfsigned.crt' in PEM format and a hostname 'susetest'. Actually I want to use the update-ca-certificates command. I tried copying the certificate into /usr/share/pki/trust/anchors/ and /usr/share/pki/trust/ as .crt and renamed to .pem. For all four scenarios the output of 'sudo update-ca-certificates -v' does not contain something like "1 added" and 'wget https://susetest' does still complain about a selfsigned certificate afterwards. Finally I managed to get it working by running 'cat /path/gnuhealth-selfsigned.crt | sudo tee -a /var/lib/ca-certificates/ca-bundle.pem'. Since this file says "Do not edit!" I'm sure this was not the proper way but I don't know how to do it properly either. Does someone have an idea what i did wrong with update-ca-certificates? The certificate was created using OpenSSL. Kind regards Gerald
