Hello: I wanted to give the TripleO a try, so started follow our installation guide for Ussuri, and eventually made it to "openstack undercloud install". It fails with something like this: Aug 28 10:10:53 undercloud puppet-user[48657]: Error: /Stage[main]/Ironic::Pxe/File[/var/lib/ironic/tftpboot/ipxe.efi]: Could not evaluate: Could not retrieve information from environment production source(s) file:/usr/share/ipxe/ipxe-x86_64.efi Aug 27 20:05:42 undercloud puppet-user[37048]: Error: /Stage[main]/Ironic::Pxe/Ironic::Pxe::Tftpboot_file[pxelinux.0]/File[/var/lib/ironic/tftpboot/pxelinux.0]: Could not evaluate: Could not retrieve information from environment production source(s) file:/tftpboot/pxelinux.0 Does anyone have an idea what it wants? I added a couple of packages on the host system that provided the files mentioned in the message, but it made no difference. Ussuri is conteinerized anyway. Since I'm very new to this, I have no clue where to look at all. The nearest task is a wrapper of some kind, so the install-undercloud.log looks like this: 2020-08-28 14:11:31.397 60599 WARNING tripleoclient.v1.tripleo_deploy.Deploy [ ] TASK [Run container-puppet tasks (generate config) during step 1 with paunch] *** 2020-08-28 14:11:31.397 60599 WARNING tripleoclient.v1.tripleo_deploy.Deploy [ ] Friday 28 August 2020 14:11:31 -0400 (0:00:00.302) 0:06:28.734 ********* 2020-08-28 14:11:32.223 60599 WARNING tripleoclient.v1.tripleo_deploy.Deploy [ ] changed: [undercloud] 2020-08-28 14:11:32.325 60599 WARNING tripleoclient.v1.tripleo_deploy.Deploy [ ] 2020-08-28 14:11:32.326 60599 WARNING tripleoclient.v1.tripleo_deploy.Deploy [ ] TASK [Wait for container-puppet tasks (generate config) to finish] ************* 2020-08-28 14:11:32.326 60599 WARNING tripleoclient.v1.tripleo_deploy.Deploy [ ] Friday 28 August 2020 14:11:32 -0400 (0:00:00.928) 0:06:29.663 ********* 2020-08-28 14:11:32.948 60599 WARNING tripleoclient.v1.tripleo_deploy.Deploy [ ] WAITING FOR COMPLETION: Wait for container-puppet tasks (generate config) to finish (1200 retries left). . . . If anyone could tell roughly what is supposed to be going on here, it would be great. I may be able figure out the rest. Greetings, -- Pete
