    Hi,
    I fresh install Debian 9.3 (XFCE4 gui) and try to install Qt 9.10 via qt-unified-linux-x64-3.0.2-online. But I realized that there is still SSL problem with Qt!.
    Error message like below;
    $ ./qt-unified-linux-x64-3.0.2-online.run
    [371] Warning: LicenseManager: Ssl error: "The issuer certificate of a locally looked up certificate could not be found"
    [372] Warning: Network error: [ QNetworkReply::NetworkError(SslHandshakeFailedError) ] "Failed to connect to server. Check your network connection and try again."

    And installed SSL version is:
    $ openssl version
    OpenSSL 1.1.0f 25 May 2017

    Why we have this error still?!...

    Regards,
    Mucip:)

      Hi,

      Did you also install the corresponding development package ?

          That’s not what I meant but it’s not important. I misunderstood the error. You have to install the OpenSSL-1.0.2 package from Debian.

          The 1.1 series broke ABI and API compatibility. Since 5.10 Qt will have a backend for it.

              Yes it is, but currently, the oldest supported Linux distributions still use OpenSSL 1.0.

              As to when the backend will be switched for the pre-built package, I don’t know.

              However, you can build Qt yourself to use the 1.1 backend.

                Hi @SGaist ,
                Re-compile is really difficult way I guess... :)
                Better to wait from Qt.

                  You can still just download 1.0 vesrion of OpenSSL in the meantime

                    Dear @VRonin,
                    I tryed before this. But I could not install Qt in this way either.

                    https://forum.qt.io/topic/82477/ssl-handshake-failed-error-during-installation/8

                    In anycase. Ok. I will download QpenSSL from here https://www.openssl.org/source/openssl-1.0.2n.tar.gz
                    and install again.

                    I will inform you about result...

                    Regards,
                    Mucip:)

                      .Hi,
                      Yes. I remove openssl 1.1 and install openssl 1.0 as said.
                      Now I started to install Qt 9.10...

                      Thanks...
