VB 5.1 won't start - could not find Qt platform plugin "xcb"

I just made a clean (older version existed, but was uninstalled and config files deleted) install of
virtualbox-5.1_5.1.0-108711~Ubuntu~trusty_i386.deb (downloaded here) on
Linux Mint 17.3 (Ubuntu Trusty based).
The installation went apparently well, except that when I try to launch VB, I get following error message:
Code: Select all
user@computer ~ $ VirtualBox U%
Qt FATAL: This application failed to start because it could not find or load the Qt platform plugin "xcb".
Available platform plugins are: xcb.
Reinstalling the application may fix this problem.
Aborted
Reinstalling it (once or twice) doesn't fix the problem; Besides, Synaptic package manager tells me some form of xcb
is installed. Apparently Virtualbox just doesn't find it.
I also tried to uninstall it, remove all configuration files, and reinstall it; The problem remains the same.
As I already said, this is
Linux Mint 17.3 (Ubuntu "Trusty" based), 32-bits, kernel #37~14.04.1-Ubuntu SMP Thu Oct 22 09:37:25 UTC 2015.
Here is (in case it helps) what the terminal said during installation:
Code: Select all
user@computer ~/Downloads $ sudo dpkg -i virtualbox-5.1_5.1.0-108711~Ubuntu~trusty_i386.deb
[sudo] password for user:

The vbox-install.log is too long to paste, so I added it as attachment:
Thank you for any insights and solutions.

You can try solution from
this thread:
P=/usr/lib/virtualbox; sudo LD_LIBRARY_PATH=$P:$P/plugins/platforms $P/VirtualBox

Anyway, it looks like a bug in the deb package.

Thanks!
Though I sure hope they will fix this bug soon?
Having to use LD_LIBRARY_PATH to run VirtualBox is suboptimal...

Take a look at ticket
#15634. I believe it is the same problem and there is a test build for you to test and contribute to the bug by posting your experience with the test build.

Will do. Downloaded the 5.1.1-108841 installer and will try it out tomorrow.

Apparently this problem has nothing to do with ticket #15634. All builds I tried since are all broken the same way, they all don't recognize Qt5 on Ubuntu 14.04 LTS, and apparently it's not going to be fixed.
So, it's LD_LIBRARY_PATH or the highway?
Isn't there a more elegant way to make VirtualBox work?
Could somebody please tell me which QT5 module contains that darn "xcb" plugin VirtualBox is asking for, so I might try to (re)install it manually?

Sorry? That went completely over my head. First, I didn't say what you quoted, and then, what's your point exactly?

Never mind, it was meant as a joke, hence the smiley
The "joke" was that you're looking for elegance in a Linux related forum. Not Linux' strongest suit.

The new version 5.1.2 with Fix #15634 did not solve the problem with the launch. I created a new ticket:

Great, thanks. Let's hope they get to fix it.
Apparently it's not bothering a lot of people, I would had expected droves of people complaining by now...

The bug was specific to 32-bit systems. Fix scheduled for 5.1.4.
