You could try using –skip-broken to work around the problem
You could try running: rpm -Va –nofiles –nodigest

To solve this problem I also added the package shown in each line “Error: Package:”

yum downgrade samba-libs-4.6.2-12.el7_4 samba-client-libs-4.6.2-12.el7_4 samba-client-4.6.2-12.el7_4 samba-common-libs-4.6.2-12.el7_4 samba-common-tools-4.6.2-12.el7_4 samba-common-4.6.2-12.el7_4 libsmbclient-4.6.2-12.el7_4 libwbclient-4.6.2-12.el7_4

On CentOS, you need to install the repository file that it is included in the extras repository

Check which package provides the library that you want.

On Red Hat Linux you can check running yum whatprovides. On my case, I need to install libnl to solve my problem

When you update your Fedora desktop, you may receive a message complaining about a public key for Google Chrome not installed on your system

Public key for google-chrome-stable-41.0.2272.76-1.x86_64.rpm is not installed

Update the repository file and add the gpgkey parameter. If you want to install, you can also create this file and then yum install google-chrome-stable

root@fedora:~ # vi /etc/yum.repos.d/google-chrome.repo

Then run again yum update or yum install google-chrome-stable and it will automatically import the public key
