Installation from current online installer won't open

[Alan Mason]

I had a previous installation of Qt Creator on a Debian 10 laptop. I installed a larger SSD and reinstalled using the newest online installer. Now even Qt Creator will not open.
If I go to the folder where it is installed and launch from terminal I get the following error:
amason@t800:~/Qt/Tools/QtCreator/bin$ sudo ./qtcreator
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.

Aborted

Any help would be appreciated.

Hi and welcome to devnet,

You are likely missing some libraries. Call ldd on the plugin and you'll see what you need to add.
