SSL handshake failed error during installation

Mucip

Dear SGaist,
I installed

mucip@debian-ev:~$ openssl version
OpenSSL 1.0.2l 25 May 2017
mucip@debian-ev:~$

But I still can not update!
I attached the picture of situation.

regards,
Mucip:)

SGaist

You should start it from the console to see if there's more debugging output.

Mucip

Dear SGaist,
I run it from console and output is:

mucip@debian-ev:~/Qt$ ./MaintenanceTool
[7561] Warning: QFile::rename: Empty or null file name

By the way when I want to run new qt online installer;

mucip@debian-ev:~/Downloads$ ./qt-unified-linux-x64-3.0.1-online.run
[5096] Warning: LicenseManager: Ssl error: "The issuer certificate of a locally looked up certificate could not be found"
[5097] Warning: Network error during login: [ QNetworkReply::NetworkError(SslHandshakeFailedError) ] "SSL handshake failed"
[5097] Warning: Unhandled connection failure: QNetworkReply::NetworkError(SslHandshakeFailedError)

I completely confused!...

Regards,
Mucip:)

SGaist

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

Mucip

Dear SGaist,
Looks like OK?

So, what is wrong?!
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:)

SGaist

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.

Mucip

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:)

SGaist

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).

Kart

I am not sure about this. Just go through this link and it might help you..

Mucip

Dear name_qt,
I can't understand very well?! Should I really rebuild all qt with libnss?!
I just want to use standart qt installation from instalaltion file which I downloaded from qt/download.

Regards,
Mucip:)

Kart

Yes @Mucip. I had this issue in Ubuntu. I was able to solve it by doing a rebuild with libnss.
You can refer this bug report too.

Mucip

Dear name_qt,
In any case, the qt company should do that, shouldn't they?
Well, qt is platform independent! But I can not install it on Debian 9?!
This is paradox, isn't it?!...

Regards,
Mucip:)

Kart

Yes @Mucip. As @SGaist have already said, i believe this problem will be solved in Qt 5.10.

Mucip

Dear name_qt,
I hope so.
Because I am very sad because of this bad situation.

Regards,
Mucip:)

Mucip

Dear @Kart ,
Qt 5.10 released but still same error!... :(

Regards,
Mucip:)

johng17

when starting to install qt in ubuntu, I faced the ssl handshake issue at logging step. I skip this test and can proceed to install.

huseyinkozan

This works:

LC_ALL=C ./qt-unified-linux-x64-3.0.5-online.run

Mucip

Hi @huseyinkozan
Yes. It works like a charm.

Mucip:)
