07. Installing packages with dependencies dnf
DNF Does Not stand For anything. It was created to solve longstanding problems with yum, such as dependency resolutions and interaction with online repositories. Furthermore, Yum's API is poorly documented, and after several bouts of poorly-managed refactoring, it has become difficult to keep the program slim and well-specified.
DNF has also improved on lower memory reduction and less automatic synchronization of metadata with respositories.
Actions
Here are five subcommands that you can use with dnf.
1) General
Here are some general commands about the dnf package itself.
- --version
- Check the version of DNF installed.
- repolist
- List all enabled repositories on your system. Add all at the end to view disabled repositories as well.
- list
- List all available packages on the repos and installed packages.
2) Searching
#dnf search vim ... vim-minimal.x86_64 : A minimal version of the VIM editor ...
3) Query

4) Installing
Instaling is similar to how it was done in yum.
#sudo dnf install vim-minimal
5) Upgrading/Updating
In dfn, upgrading and updating mean the same thing.
# Update just vim-minimal#dnf update vim-minimal # Update all installed software#dnf upgrade
