I'd like to find out if there are differences between yum update and dnf upgrade.
I am using CentOS 7. I haven been using BOTH commands at the same time.
And I just tried it again and this is what happened:
yum update

Dependencies resolved.
Nothing to do.
To me it seems they are showing different updates. But I could be wrong.

What are you expecting? Neither is offering any new packages to update. They should be the equivalent command. You just went out of your way and installeddnfon CentOS before it migrated there from Fedora.

Thank you Aaron. One of the reasons that I installed dnf was because I was told that yum is going outdated, and I should start using dnf. Now I have been curious which one actually shows a better updating results. - Denny

Second,yumwill not go away while CentOS 7 is still current. The earliest you'll see it go away and be superseded bydnfis with RHEL8/CentOS8.

You should first run update, then upgrade.
Read Updating Packages from the Command Line with yum
What is the technical differences between “update†and “upgrade†with yum?
update:
If run without any packages, update will update every currently installed package. If one or more packages or package globs are
specified, Yum will only update the listed packages. While updating
packages, yum will ensure that all dependencies are satisfied. […]
If […] the --obsoletes flag is present yum will include package obsoletes in its calculations - this makes it better for
distro-version changes, for example: upgrading from somelinux 8.0 to
somelinux 9.
upgrade:
Is the same as the update command with the --obsoletes flag set.
In CentOS, what is the difference between yum update and yum upgrade?
Yum vs DNF
Compared to Yum, DNF offers:
- Better dependency management
- Support Extensions other than Python
- Documented API
- Lower memory usage
- Less automatic synchronization of metadata with repositories, a process that users often complain "happens too often and takes too much time."
