Error: Package: mysql-community-server-5.7.40-1.el6.x86_64 (mysql57-community)

Requires: libsasl2.so.2()(64bit)

You could try using --skip-broken to work around the problem

You could try running: rpm -Va --nofiles --nodigest

Cause:

Baseurl in repo config file is mapped to old release.

Solution:

# cat /etc/yum.repos.d/mysql.repo

[mysql57-community]

name=MySQL 5.7 Community Server

## baseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/6/$basearch/

baseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/7/$basearch/

enabled=1

gpgcheck=0

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql
