SSL handshake failed error during installation
-
I am following this https://www.ics.com/blog/getting-started-qt-and-qt-creator-linux to install Qt on KDE Ubuntu.
But SSL handshake fails when I login and I cannot seem to resolve this. Here is a screenshot. https://drive.google.com/open?id=0B_CFF1scHyiSMFRwQXhVeWx4eW8 and https://drive.google.com/open?id=0B_CFF1scHyiSUWMtR3N0SjM3clU.I did find some ssl certificate related stuff on the Internet but nothing helped. Please guide me on what should I do.

Hi and welcome to devnet,
What version of Qt are you using ?
What version of OpenSSL do you have installed ?
How did you install Qt ?
Which version of Ubuntu/Kubuntu is it ? -
@SGaist Hello!
I am installing Qt 5.9.1
OpenSSL 1.1.0f
I installed Qt using open source online installer and ubuntu 16.04This problem occurred when I was using the wifi network of our college campus. I switched to mobile data and now the installation works fine.
Thanks. -
Currently Qt 5 can't work with OpenSSL >= 1.1.0. They broke API and binary compatibility. There's a new backend in the works. In between you need to install a 1.0.X version beside your 1.1.X version.

@SGaist I did not understand why? I installed before on my Debian 9 but now I make new Debian 9 machine and try to install QT5 online installer. But I could not install now! But I installed before?!
What did they change? And do I need to install old OpenSSL?! Is there any other solution?

What did you not understand ?
Try Installing libssl1.0

Dear SGaist,
I checked;mucip@debian-ev:~$ openssl version
OpenSSL 1.1.0f 25 May 2017I followed the below website and install openssl 1.0.0.
https://www.computersnyou.com/3155/update-install-openssl-source-latest-version/Now the situation is;
mucip@debian-ev:~$ openssl version
OpenSSL 1.0.0s 11 Jun 2015But I can not update maintenance tool and I can not even run qt-unified-linux-x64-3.0.1-online.run from my computer?!
Where am I wrong?!
Regards,
Mucip:) -
Instal the libssl1.0.2 package.
-
You should start it from the console to see if there's more debugging output.
-
Dear SGaist,
I run it from console and output is:mucip@debian-ev:~/Qt$ ./MaintenanceTool
[7561] Warning: QFile::rename: Empty or null file nameBy the way when I want to run new qt online installer;

Looks like the OpenSSL libraries are correctly working. Can you run
ldd qt-unified-linux-x64-3.0.1-online.runjust to be sure ? -
Dear SGaist,
Looks like OK?

And am I first person who is faced with this problem?!...
Is there anybody out there who can use Debian 9 and Qt?...Regards,
Mucip:) -
Debian 9 switched to OpenSSL 1.1 which will be supported by Qt 5.10. You should not have any problem if you use the Qt version provided by Debian but it will likely be a bit older.
Otherwise if you'd like to have cutting edge Qt, KDE Neon is also a possibility.
-
Dear SGaist,
Unfortunately I do not think that this problem is about Debian 9. Because I installed Qt 5.9 on Debian 9 on 23th June 2017.
But somehow I can not install new one or even update now?! Same Debian 9 and same Qt 5.9
There must be something changed by Qt side I guess?!By the way there isn't any problem on Windows platform.
I can not understand this. We say "Qt is platform independent" but I can not install it on Debian?!...
Regards,
Mucip:) -
No, more likely something changed on your system, and likely in OpenSSL.
You can't compare installation on Windows and Debian, those are two radically different platforms with different requirements.
In any case, the custom certificate error might lead to something. I'd recommend taking a look at the bug report system to see if there's something related. If not please open a new report providing all the possible details about your system and the currently installed versions of OpenSSL (all of them).
