Error Installing Qt 5.15.2 on Linux Mint LMDE 4 (Debian 10.10)

[ad5xj]

I am attempting to install Qt 5.15.2 on a machine running Linux Mint LMDE 4 64-bit (Debian 10.10).
There are a couple problems:

1. The shortcuts to the Maintenance Tool and QtCreator do not get added to the Programming menu
2. If I attempt to start QtCreator manually from a terminal it cannot load the "xcb" modules even though they exist.

A check with synaptic verifies that.

So where do I look now?

BTW installation is from the online installer app qt-unified-linux-x64-4.1.1-online.run (verified)

Debian 10.10

You need xcb >= 1.11: https://doc.qt.io/qt-5/linux-requirements.html

As it turns out Debian 10.10 on which Mint LMDE 4 is built has libxcb v 1.14-2

There might be something else missing.

Start Qt Creator with the QT_DEBUG_PLUGINS environment variable set to 1 to get more information about what is going on.
