In Ubuntu 18.04, Audacity is in a loop, where no matter what location I type into the dialog, it keeps saying
Audacity could not find a safe place to store temporary files.
Audacity needs a place where automatic cleanup programs won't delete the temporary files.
Please enter an appropriate directory in the preferences dialog.1 Answer
If you install audacity via the snap package manager, it does not work. It must be installed with apt
So the solution was
sudo snap remove audacity
sudo apt-get install audacity -y
