We get questions about the normality of residuals from models, e.g., Dependent variable - bimodal? Often, as in this example, it turns out that the OP wants to perform inference on model parameters and believes that residuals need to be normally distributed for inference to be valid.

I would have expected to find a highly voted question in the tag that I could use to VTC as a duplicate, but I couldn't find it.

Where is our canonical answer to questions about normality of residuals and inference?

whuber pointed to a very nice search. It seems to me like the following thread is the most useful one for our purposes here: Regression when the OLS residuals are not normally distributed.
