What is the preferable distribution for target variable in a regression task? If my target variables do not conform such distribution, how can i fix that? Is there a problem in regression which is equivalent to class imbalance in classification?

Usually normal distribution is used to fitted with target distribution, but if it is a multimodal, you can try Gaussian Mixture Models (GMMs). But if it is unimodal, but non-symmetric you can try fitting parameterized distribution through MLE (see Fitting a gamma distribution with (python) Scipy), or try transforming your variable through non-linear transformations such as log transform or box-cox transformation)
