For the last few days I had a very interesting (read: ultra annoying) issue with Windows 10 on my Surface Pro. No matter which network I was connecting to, I could never see the internet anymore.

Logic dictates that there was perhaps an issue with the router, but since it happened on other networks as well, this couldn’t have been the case. I could even ping the router, but no matter what else I tried, Windows didn’t see the internet.

How to fix duplicate packages in yum

by

From time to time, the yum package manager may encounter issues with duplicate packages that are erroneously installed on a system. This manifests in a yum update going awry, telling us something along the lines of this:

yum update

--> Finished Dependency Resolution
Error: Package: ntp-4.2.6p5-22.el7.centos.2.x86_64 (@updates)

           Removing: ntpdate-4.2.6p5-22.el7.centos.2.x86_64 (@updates)
               ntpdate = 4.2.6p5-22.el7.centos.2
           Updated By: ntpdate-4.2.6p5-25.el7.centos.x86_64 (base)
               ntpdate = 4.2.6p5-25.el7.centos
 You could try using --skip-broken to work around the problem
** Found 41 pre-existing rpmdb problem(s), 'yum check' output follows:

You may at times install all other packages via yum update –skip-broken, but it will still leave some trouble on the system. Best to take care of it.

Here’s how I’ve managed to do it on many occasions:
