Connect won't start due to missing Qt platform plugin "xcb"

This KB is for customers attempting to run Connect 3.7.4 on Ubuntu 16.04 LTS.

When starting Connect, you will receive the following error message:

This application failed to start because it could not find or load the Qt platform plugin "xcb" in "". Available platform plugins are: xcb. Reinstalling the application may fix this problem. 
Aborted (core dumped)

To rectify this, do the following:

  1. Back up the current lib file:
    # mv ~/.aspera/connect/lib/libstdc++.so.6  ~/.aspera/connect/lib/libstdc++.so.6.BCK
    
  2. Replace it with the system version of the file:
    # cp /usr/lib/x86_64-linux-gnu/libstdc++.so.6 ~/.aspera/connect/lib/
    

Connect should now be able to start.
