When I want to be careful about running these setup scripts, especially just for trying out new software, I run them in a docker container to limit whatever damage the scripts can cause. When the script is complicated, I tend to use docker instead of trying to understand the script and then run it on the 'real' system.

Then when I really like the software and want to install it on the 'real' system, if there's much benefit in doing so, I spend more time and effort understanding the script. More often than not, I end up not doing this because there is no compelling need to install the software on the 'real' system.
