The assumption that the distribution of error terms will be skewed to left or right is not a requirement for the simple linear regression model. Instead, the assumption is that the error terms are normally distributed with mean zero and constant variance. The other assumptions are that the error terms have equal variances for all values of the independent variable, the error terms are independent of each other, and the mean of the dependent variable for all levels of the independent variable can be connected by a straight line.
