I deal with biology researchers trying to install various analysis programs. Python has caused me some pain recently. Its not easy, some use python 2.7 some packages use python 3.0. Many use different environments (pyenv/conda..). I ended up with a separate environment for each package..

To be fair java based software install isn't much better.

R is oddly a standout, in ease of installing packages. (Except the one time it didn't work, but in this case it wasn't much worse than anything else).

In general software distribution could be made much better.
