What does this mean?

I do this a number of times but being a newbie, dont exactly know, what yum is trying to do?

Trying to increase my understanding of Linux or may be Yum.......

Thank You

Metadata I believe would be things like file history and build numbers, so I would suggest it is checking the versions of packages you have to check if they are up to date before trying to update them.

A combination of the repo files that list where to get updates from eg /etc/yum.repos.d (RHEL/centos) and the rpm database.

Thanks r3sistence for the try........

Ok.............

It means the repository configuration files stored in yum.repos.d

which are present there because of the repositories for which i have configured yum.


Thank You!

Yum checks for updates by comparing it's own local metadata with the data in all of the configured remote repositories. Usually this is done done only once a day, if yum is used multiple times during the day.

Linux

i have a question:

What if a package is available in two different repositories?
Which one will be used to install the package?
