virtualbox suddenly stopped working, Segmentation fault (core dumped)

Question

I was working with virtualbox on ubuntu 14.04 suddenly it closed and didn't start afterward. when I tried to load it from terminal it showed me LibQtCore.so.4 file too short, which I've fixed it by reinstalling all needed libraries.

but after rebuilding libraries when I try to open virtualbox from terminal I get :

Segmentation fault (core dumped)

And there is no clue what should I do to fix this. Also my vlc and clementine players has the same status.

what should I do to fix this?

Just to be sure, do a memtest to see if your RAM is failing. — fkraiem, Jan 06 '18 at 05:23
@fkraiem sure i will, but i don't it's ram problem. I have 32 gig ram. and never had a problem with it. — Mohammad_Hosseini, Jan 06 '18 at 05:24
@NerdOfCode I've just tried, I removed it entirly and result was the same. — Mohammad_Hosseini, Jan 06 '18 at 05:56
It seems you ignore message about Qt. Try to reinstall corresponding package with sudo apt-get install --reinstall libqtcore4. You can try to scan your system with debsums like in my other answer. — N0rbert, Jan 06 '18 at 10:25
@N0rbert I've reinstalled qt libraries and followed your approach and the other answer approach too, but still no success. — Mohammad_Hosseini, Jan 08 '18 at 08:21

I have had similar issues with virtualbox myself.

I was running on the latest virtualbox 5.2.6 on my ubuntu 16.04.

I did a purge and autoremove all of its libraries+virtualbox.

Installed previous stable version - 5.1.32 and its extensions.

Everything worked fine ever since.

Try to run these commands:

sudo apt-get update
sudo apt-get install -f
sudo apt-get purge virtualbox-5.2.x
sudo apt-get autoremove
sudo apt-get install virtualbox-5.1

if you can't install it from commandline then go to their website: https://www.virtualbox.org/wiki/Downloads

Download the 5.1.32 for ubuntu 14.04/16.04 install the .deb file package by:

sudo dpkg -i virtualbox-5.1_5.1.32-120294_Ubuntu_xenial_amd64.deb

Let us know how it goes.
