Created attachment 1607868 [details] contents of /tmp directory from the VM where the installation failed Description of problem: When installing FC30 on a KVM virtual machine from the ISO image downloaded at https://download.fedoraproject.org/pub/fedora/linux/releases/30/Server/x86_64/iso/Fedora-Server-dvd-x86_64-30-1.2.iso, I receive the following error: "DNF error: Error in POSTTRANS scriptlet in rpm package kernel-core" Version-Release number of selected component (if applicable): Fedora 30-1.2 Host system is also running Fedora 30 on kernel 5.2.9-200.fc30 and libvirt-daemon-5.1.0-9 How reproducible: Always Steps to Reproduce: 1. Create a VM with the following command: virt-install --name fc30-base-20190818 --vcpus 2 --cpu host --memory 4096 --location /u01/kvm/datastore/iso/Fedora-Server-dvd-x86_64-30-1.2.iso --os-variant fedora29 --disk size=50 --network default --noautoconsole 2. Start the graphical install by running "virt-viewer fc30-base-20190818" 3. Install the VM as follows: - UTC time - NTP enabled - Hostname 'fc30-base-20190818' - Base server package + Guest Agents - DHCP for interface - IPv6 Automatic - Storage: - LVM + XFS (vg_root): - /boot 1G (non-LVM) - /home 4G (lv_home) - /opt 4G (lv_opt) - /var/log 10G (lv_var_log) - /var 20G (lv_var) - / rest (11G) (lv_root) - Set root pass - No additional user Actual results: Install runs OK until "Configuring kernel-core.x86_64" where it dies with the error dialog: "The following error occurred while installing. This is a fatal error and installation will be aborted. DNF error: Error in POSTTRANS scriptlet in rpm package kernel-core" There are no tracebacks only an "Exit Installer" button. Expected results: Install completed successfully Additional info: Issue does not occur in the non-graphical installer, i.e. create the VM with the following options: virt-install --name fc30-base-20190818 --vcpus 2 --cpu host --memory 4096 --location /u01/kvm/datastore/iso/Fedora-Server-dvd-x86_64-30-1.2.iso --os-variant fedora29 --disk size=50 --network default --noautoconsole --extra-args='console=ttyS0'
All RPM errors are fatal during the installation (see the bug 1565123). Reassigning to kernel.
The posttrans script runs the kernel-install which is just a wrapper around dracut. I'd like the dracut team to take the first look.
I tried to find out what is happening. Chrooting in the sysimage I launched the final posttrans script command: /bin/kernel-install add 4.18.0-80.el8.x86_64 /lib/modules/4.18.0-80.el8.x86_64/vmlinuz And it ended with error: Could not determine the kernel command line parameters. Please specify the kernel command line in /etc/kernel/cmdline! Related to: https://code.obermui.de/GitHub-Mirror/systemd/commit/88e1306af6380794842fb31108ba67895799fab4 ?
I think the issue is now fixed upsteam by the commit pointed in previous comment. In the meantime, the workaround is to add a harmless (useless) extra arg to virt-install, like “--extra-args ro”. Regards
