<![CDATA[Qt Creator fails to launch on Ubuntu 20.04]]>New out of the box Ubuntu 20.4 install. Updated.

  • Sudo apt-get install build-essential
  • Newly downloaded commercial Qt Install
  • Creator won't run, hence any apps you write won't run

There are a number of solutions provided, but they are wrong...or incomplete. An old thread has the complete, right answer that got me unblocked.

Start Qt Creator from the command line with the QT_DDEBUG_PLUGINS environment variable set to one.

You should be able to see which library you are missing.
