We are trying to create an ISO image using the repository. For the testing purpose, we are using the centos mirror “CentOS Mirror” and added it to the repository for a build.
We have configured the smart proxy with DHCP, TFTP in the foreman with katello. while configuring the host with the same name, we are getting an error of “has already taken”.
We have created a new hostname and configured it with a smart proxy. When initiating the build process, we are getting the “Unable to set DHCP entry” and “Failed to perform a rollback on Remove DHCP Settings” error.
We figured out that the proxy is already running in another DHCP connection which is created along with the installation of foreman with katello in the server. We have also check all the host list details in the foreman and we couldn’t find any running proxy on the server.
How do we rectify this error to initiate the build process…?
