### Bug Description Launching the core24 image intermittently fails and is blocking up our CI. ### To Reproduce 1. `lxc remote add craft-com.ubuntu.cloud-buildd-daily https://cloud-images.ubuntu.com/buildd/daily --protocol simplestreams` 2. `lxc launch craft-com.ubuntu.cloud-buildd-daily:core24` It often will start working after 5-10 attempts of retrying the second step. The next troubleshooting step is to run `lxc launch --debug craft-com.ubuntu.cloud-buildd-daily:core24` then reach out to the LXD and/or cloud image teams. ### part yaml _No response_ ### Relevant log output ```shell logger.debug( "Failed to launch instance %s, retrying %s.", instance_name, retry_count, ) logger.debug(str(error)) # Ignore first 3 failed "create" attempts that other craft-providers # are creating the same instance. # LXD: Instance is busy running a "create" operation if retry_count >= 2 or ( error.stderr and '"create"' not in error.stderr.decode() ): > raise LXDError( brief=f"Failed to launch instance {instance_name!r}.", details=errors.details_from_called_process_error(error), ) from error E craft_providers.lxd.errors.LXDError: Failed to launch instance 'itest-SERAAXYI'.
