can someone direct me to a help about installing packages? I'm still drying to install chrome

edit

Another option is install gnome-software,

$ sudo dnf install gnome-software

Then install the google-chrome third-party repository,

• Open gnome-software
• Open the application menu (Super+F10 on gnome desktop), since you are on fedora-kde-spin , click on the top left corner icon and select "Software Repositories".
• On the pop-up windows enable "Third Party Repositories", then close the windows.
• Open the application menu and select "Software Repositories" again.
• Now enable "google-chrome" repository, close the windows.
• Now click on the magnifying glass, then type chrome, if you have problems searching chrome close the app and reopen it.
• Then install "Chrome browser".

By command line

Enable the third party repositories

$ sudo dnf install fedora-workstation-repositories

Then enable google-chrome (repo id) repository, remember the repo-id not the repo-name that is a tiny mistake in the previous link, but you can check the documentation, if you don't know the repo id run
$ dnf repolist disabled first.

$ sudo dnf config-manager --set-enabled google-chrome

Then install google-chrome-stable (package name)

$ sudo dnf install goole-chrome-stable

Command line key installation for RPM

On an RPM-based system (Fedora, SUSE, Mandriva, RHEL, etc.), download the key and then use rpm to install it.

wget https://dl.google.com/linux/linux_signing_key.pub

sudo rpm --import linux_signing_key.pub

You can verify the key installation by running:

rpm -qi gpg-pubkey-7fac5991-*

To manually verify an RPM package, you can run the command:

rpm --checksig -v packagename.rpm
