That doesn't match my experience at all; people usually realize that there are tons of reasons not to use the repo version. Perhaps you want a newer Python than the crusty old one that comes with 18.04. perhaps you want to test something that doesn't exist in the repos (the horror!). Docker and Elastic both recommend using their repos or building from source rather than using the geriatric versions in the Ubuntu repos.
