Thank you for your help! Based on runtime error, the format is inst.addrepo=name,url I used this command: sudo virt-install -l http://hkg.mirror.rackspace.com/fedora/releases/34/Everything/x86_64/os/ --disk path=/dev/disk/by-id/ata-Samsung_SSD_850_EVO_250GB_S21MNSAFC02148L-part4 --name f34-uefi-dpt --ram 2048 --boot uefi --extra-args="inst.addrepo=rackspace,http://hkg.mirror.rackspace.com/fedora/updates/34/Everything/x86_64/" It is exactly what I wanted as updates are installed. Just that the option of "not install update" is greyed out in this way. _______________________________________________ test mailing list -- test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to test-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/test@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
