That was the systemś answer:

Reinstalling the application may fix this problem.

See if you have the following directory with the plugins libraries,

$ ls /usr/lib/x86_64-linux-gnu/qt5/plugins/platforms

There should be a libqxcb.so listed in that directory if you have them.

Also try setting the following in your environment

$ export QT_DEBUG_PLUGINS=1

- then try running freeview again and see what it reports.

- R.

Hello, I am working with Ubuntu 18.

I did what you asked to me, but the results are the same:

jcrn12@jcrn12-VirtualBox:~$ sudo apt-get install qt5-default  qtcreator
Reading package lists... Done

qtcreator is already the newest version (4.5.2-3ubuntu2).
qt5-default is already the newest version (5.9.5+dfsg-0ubuntu2.1).

Then, I tried:

jcrn12@jcrn12-VirtualBox:~$ libxcb.so.1 => /lib64/libxcb.so.1 
bash: /lib64/libxcb.so.1: Permission denied

What could be the next step?

Thanks a lot,

JC.

Are you working on Ubuntu 18 ?
