Hey! I have a question about this script.

When I'm running “apt-get update” after adding the source to the list I see this line in the output:
Hit http://repo.mysql.com trusty InRelease
and
Hit http://repo.mysql.com trusty/mysql-5.7 amd64 Packages

But when I do “apt-cache search mysql-server-5.7” i see nothing. And “apt-cache show mysql-server” it gives me version 5.5

What could've possibly went wrong during that script so I miss the 5.7 package?
