I don't think that will make a difference, 5.7 is the version shipping
with ubuntu now. The only one important is mysql-server and you have 5.7
so that should be OK. The latest mysql is version 8. I am using mariadb
which is at version 10. It seems ubuntu ships newer versions of mariadb
than of mysql.
Perhaps you have some network problem. Using ethernet try plugging it
differently, into a different router if possible. Also try different cables.
