I'm trying to access the bootstrap site and I get an error with sha384 hashes. How can I solve the problem?

Question

linux

I have linux firefox trying to access sites:
bootstrap-4.ru
https://v4-alpha.getbootstrap.com/
getting an error

None of the “sha384” hashes in the integrity attribute match the content of the subresource.

In general, the question is what kind of garbage)) I can’t find a solution)) can anyone come across ???

Answer 1

It looks like the sites you are trying to visit did not update the integrity attributes in styles and scripts. They link to the beta version of bootstrap4, and there is no beta label on getbootstrap.com .
