I use dnf priority to isolate the core system from 3rd party software.
It means a 3rd party package cannot upgrade a baseos package.
Here is my /etc/yum.repos.d/rocky.repo
[baseos] name=Rocky Linux $releasever - BaseOS mirrorlist=https://mirrors.rockylinux.org/mirrorlist?arch=$basearch&repo=BaseOS-$releasever$rltype gpgcheck=1 enabled=1 countme=1 metadata_expire=6h gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-Rocky-10 priority=10
The rule is that if a [repository] has "enabled=1" then add "priority=X" to establish it's hierarchy among other repos.
The hierarchy usually is:
priority=10 for [baseos]
priority=20 for [appstream]
priority=20 for [crb]
priority=30 for [extras]
priority=40 for [epel]
priority=50 for [google-chrome]
priority=90 for [fedora]
Install epel repo, the Fedora Special Interest Group (with priority=40).
dnf install epel-release
Install Gnome Desktop
dnf group install Workstation systemctl set-default graphical.target systemctl enable gdm.service # Create $HOME template directories, e.g. Documents, Downloads, Music, Trash as $HOME/.local/share/Trash # Run as regular user xdg-user-dirs-update
Create /etc/yum.repos.d/google-chrome.repo
[google-chrome] name=google-chrome baseurl=https://dl.google.com/linux/chrome/rpm/stable/x86_64 enabled=1 gpgcheck=1 gpgkey=https://dl.google.com/linux/linux_signing_key.pub priority=50
Install software from RESF repos
dnf install emacs thunderbird google-chrome-stable dnf group install "Development Tools"
Add flathub and use Gnome Software to add more programs.
Ristretto, Gimp, Evince, File Roller, LibreOffice, Vlc, Meld, FileZilla
After reboot adjust few settings
Settings -> Displays -> Unknonw Display : disable it to avoid hidden window going offscreen. Settings -> Power -> Power Saving -> Screen Blank:never, Automatic Suspend:Off, Power Button Behavior:Power Off
Install KVM.
For setting up KVM with a Bridge Interface read kvm-centos.
For setting up KVM with NAT forwarding (aka "virtual networks") read libvirt networking.
For setting up KVM in general on rockylinux-10 read kvm-on-rocky-linux-10.
dnf groupinstall "Virtualization Host" dnf groupinstall "Development Tools" dnf install virt-install virt-manager virt-top virt-viewer libguestfs-tools net-tools bridge-utils wget curl usermod -aG libvirt $USER usermod -aG kvm $USER systemctl start libvirtd systemctl enable libvirtd lsmod | grep kvm virsh net-list --all brctl show # Setup host NAT forwarding vi /etc/sysctl.conf net.ipv4.ip_forward = 1
Install VirtualBox-7.1
dnf install install kernel-devel kernel-headers gcc gcc-c++ glibc make bzip2 \
dkms perl elfutils-libelf-devel libX11-devel libXt libXmu
curl http://download.virtualbox.org/virtualbox/rpm/rhel/virtualbox.repo -o /etc/yum.repos.d/virtualbox.repo
vi /etc/yum.repos.d/virtualbox.repo
# add priority=50
dnf install VirtualBox-7.1
VBoxManage -v
cd /tmp
curl -O http://download.virtualbox.org/virtualbox/7.1.12/Oracle_VirtualBox_Extension_Pack-7.1.12.vbox-extpack
VBoxManage extpack install Oracle_VirtualBox_Extension_Pack-7.1.12.vbox-extpack
# agree the license terms
Do you agree to these license terms and conditions (y/n)? y
VBoxManage list extpacks
# if the modules need to be rebuilt, then usually run
/sbin/vboxconfig
# VirtualBox is in conflict with QEMU/KVM and both cannot run at the same time.
# Remove kvm modules before starting a VM image.
lsmod | grep kvm
rmmod kvm_intel
rmmod kvm
Add own RHEL repository.
