Developement Tools

Hi,

I am very new to Rocky Linux, installed 9.1.
Why is it showing blank? Could any one explain this?

$ sudo dnf groupinstall 'Development Tools'

Thanks in advance.

Is it possible you already installed it (from anaconda, etc)? Thats what it would return if you had

then it should return the output “Installed”, not expect blank something what i am getting.

Can you do:

dnf grouplist

and post the output? Either way, it’s the same in RHEL. If the group of packages is not installed, it then installs the packages that are part of that group. If it’s all installed, then it just says complete just like yours. You could always open a bug with Red Hat about it if you feel that the output should be more informative. Either way, the fact it doesn’t install anything, means that it’s all installed. Otherwise it would have installed the packages.

The grouplist command will confirm that anyway.

I’m not getting the same results. Check dnf grouplist as @iwalker suggested. There is a chance you may already have the required packages installed.

One can also:

sudo dnf group info -v 'Development Tools'

that should both list the packages in the group and whether some of them are installed.

Yes, its already installed. however sudo dnf groupinstall ‘Development Tools’ should return the output “Installed”, not expect blank something what i am getting.

As I said, it does this in RHEL, so if you think it’s not enough output and you expect that it actually needs to tell you more, you can open a bug report here with Red Hat: https://bugzilla.redhat.com/

Since Rocky is based on RHEL, and the fact it doesn’t tell you in RHEL either, that is the way you need to get it fixed. Otherwise, it’s a case of “complete” being the output that tells you it’s installed, as well as checking the grouplist. Personally I don’t see a problem with it. If there were packages to install, you would see a big list of packages. If you see nothing, then it means there is nothing to install - because it’s already installed.

Also, please format your posts properly using the tools in the post editor window since it makes it much easier for people to read what is text, and what is console output. Like what I fixed above in your posts.

Try this to show optional packages

dnf groupinstall -v ‘Development Tools’ --setopt=group_package_types=mandatory,default,optional
