I think I have managed to make the certificate known to curl following the instructions here: https://help.ubuntu.com/community/OpenSSL
copying it to /usr/share/ca-certificates/ adding it to /etc/ca-certificates.conf running sudo update-ca-certificates However I still think the error output of curl or it's documentation needs updating (certainly the reference to curl-ca-certificates.crt is misleading). I was already ready to give up and only found this solution by chance. -- curl does not find ssl certificates, reports wrong default location https://bugs.launchpad.net/bugs/403461 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
