Check if there is a problem with the network connection. Check if port 443 is blocked or if the corresponding Repository IP address is blocked by the Firewall. Check if there is a problem with the Fortimonitor.repo mirror server. Upon reviewing the logs in this particular example, the 4th cause was determined to be responsible. Upon changing the baseurl of fortimonitor.repo as follows, the installation was successful. vi fortimonitor.repo(Default settings of fortimonitor.repo) [fortimonitor.repo] name=FortiMonitor Repository baseurl=http://repo.fortimonitor.com/rpm8-stable/ enabled=1 gpgcheck=1 gpgkey=https://repo.fortimonitor.com/fortimonitor.pub The baseurl was changed to: cat fortimonitor.repo [fortimonitor.repo] name=FortiMonitor Repository baseurl=https://rocky-linux-asia-south1.production.gcp.mirrors.ctrliq.cloud/pub/rocky//8.8/BaseOS/x86_64/os/ enabled=1 gpgcheck=1 gpgkey=https://repo.fortimonitor.com/fortimonitor.pub
