 You could try using --skip-broken to work around the problem
** Found 1 pre-existing rpmdb problem(s), 'yum check' output follows:
python-requests-2.6.0-10.el7.noarch has missing requires of python-urllib3 >= ('0', '1.10.2', '1')
Could not automatically sync with Anolis OS repositories.
        Check the output of 'yum distro-sync' to manually resolve the issue.
