I Try to Yum Updates in Cent Os, but seem same result, Error
You could try using --skip-broken to work around the problem
** Found 36 pre-existing rpmdb problem(s), 'yum check' output follows:
1:NetworkManager-1.18.0-5.el7_7.2.x86_64 has missing requires of NetworkManager- libnm(x86-64) = ('1', '1.18.0', '5.el7_7.2')
1:NetworkManager-team-1.18.4-3.el7.x86_64 has missing requires of NetworkManager (x86-64) = ('1', '1.18.4', '3.el7')
1:NetworkManager-tui-1.18.4-3.el7.x86_64 has missing requires of NetworkManager = ('1', '1.18.4', '3.el7')
binutils-2.27-43.base.el7.x86_64 is a duplicate with binutils-2.27-41.base.el7_7 .3.x86_64
I Will try to fix the Yum update maybe can help
