You can try to call it with strace or from gdb to see what happens.
Do you have anything related to Qt in your PATH?

Sudhir Khanger

@jsulm I don't have anything related with Qt in PATH.

How do I trouble shoot the run file in gdb?

I tried gdb then file qt-unified-linux-x64-2.0.3-online.run and exec-file also.

"/location/to/qt-unified-linux-x64-2.0.3-online.run" is not a core dump: File format not recognized

One way, is run it like:

gdb /location/to/qt-unified-linux-x64-2.0.3-online.run

Then, at the gdb prompt, type run and hit enter.

To use strace:

strace /location/to/qt-unified-linux-x64-2.0.3-online.run

Cheers.

That suggests the installer itself is corrupt - ie didn't download correctly.

-rwxrwxr-x. 1 sudhir sudhir 3910591 Apr 13 09:34 qt-unified-linux-x64-2.0.3-online.run

Looking at https://download.qt.io/archive/online_installers/2.0/qt-unified-linux-x64-2.0.3-online.run.mirrorlist the file should be 30392080 bytes - yours appears to be about one tenth of that.

Try downloading the installer again, then check one of the md5 / sha sums.

Cheers.

Sudhir Khanger

@Paul-Colby Thanks. I should have check that myself. I have tried downloading the image several times. It downloads very slowly and eventually dies. Maybe the download page is broken. Even from mirror downloads break at 3.4MB.

Sudhir Khanger

Okay after several tries I was able to download uncorrupted installer image. Thank you.

Glad to hear you got it working :)

Don't forget to mark this topic as "Solved" :)

Sudhir Khanger

@Paul-Colby The main download is still broken but I would mark it as solved. Thanks for helping out.
