OS / ENVIRONMENT

Fresh Debian 11 setup

SUMMARY

If lsb_release isn't installed (which is not on Debian 11), the rolewill fail:

fatal: []: FAILED! => {"msg": "The conditional check '(ansible_lsb.id != 'Univention' or ansible_distribution_release != 'stretch')' failed. The error was: error while evaluating conditional ((ansible_lsb.id != 'Univention' or ansible_distribution_release != 'stretch')): 'dict object' has no attribute 'id'\n\nThe error appears to be in '/tmp/semaphore/.ansible/roles/adfinis-sygroup.icinga2_agent/tasks/installation.yml': line 38, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n- name: configure icinga apt repository\n ^ here\n"}

STEPS TO REPRODUCE

Run role against Debian 11 Host
