Virtualbox doesn't start, xcb error

[ajavibp]

Hello,
I'm crazy because of a VirtualBox error that I can not solve.

Qt FATAL: This application failed to start because it could not find or load the Qt platform plugin "xcb"
in "".
Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, xcb.
Reinstalling the application may fix this problem.

Of course, reinstallation does not help at all, I even got to have a full purge and it keeps the error when reinstalling.
ldd -r /usr/lib/virtualbox/VBoxRT.so shows no problems (pastebin).
ldd /usr/lib/x86_64-linux-gnu/qt5/plugins/platforms/libqxcb.so shows no problems (pastebin).
Going manually to version 5.1.18 serves as a workaround, but I would not like to keep it that way.
Thank you very much in advance for your help.

How did you install vbox  ? Straight from debian or downloaded from oracle ?

I have no problems (debian version)  and use it daily to test siduction and my builds

You could try as root after purge

Code Select Expand

updatedb


then reinstall

Code Select Expand


piper@x1:~$ apt policy virtualbox

Thanks piper for your support.
I usually install it directly from debian, but I have also tried it from Oracle. Any version after 5.1.18 causes me the same error.

Of course, I already tried also with the advice of the links that you send me. That's why I said I'm crazy about this error. I use other programs that use Qt, like Kile, without any problems.

just a guess, biut check you ~/.virtuelbox folder if you have 0byte files.

[ajavibp]

After the purge and reinstall I have no .virtualbox folder (neither similar names) 

[ajavibp]

I still can not get the virtualbox of the repositories to work. At the moment it only works for me if I install virtualbox-5.1_5.1.26-117224-Debian-wheezy_amd64 directly.
Any ideas?

virtualbox-5.1_5.1.26-117224-Debian-wheezy_amd64 is absolute wrong!

You need the stretch package as minimum!

[ajavibp]

If curious, but wheezy is the only works for me. I tried stretch, ubuntu and, of course, repository versions. 5.0 version has module compilation problems, and 5.1 doesn't start because rhe 'xcb' error. I tried all the solutions that I saw in Google too
