[DEPRECATION WARNING]: The TRANSFORM_INVALID_GROUP_CHARS settings is set to allow bad characters in group names by default, this will change, but still be user configurable on deprecation. This feature will be removed in version 2.10. Deprecation warnings can be disabled by setting deprecation_warnings=False in ansible.cfg. [WARNING]: Invalid characters were found in group names but not replaced, use -vvvv to see details

TASK [ros : Setup the source lists] ********************************************************************************** [WARNING]: Consider using 'become', 'become_method', and 'become_user' rather than running sudo

TASK [ros : Set up keys] ********************************************************************************************* [WARNING]: Consider using the get_url or uri module rather than running 'curl'. If you need to use command because get_url or uri is insufficient you can add 'warn: false' to this command task or set 'command_warnings=False' in ansible.cfg to get rid of this message.

TASK [ros : Update and upgrade apt packages] ************************************************************************* [WARNING]: The value True (type bool) in a string field was converted to 'True' (type string). If this does not look like what you expect, quote the entire value to ensure it does not change.

TASK [robots : Rules for realsense download] ************************************************************************* [WARNING]: Consider using the get_url or uri module rather than running 'wget'. If you need to use command because get_url or uri is insufficient you can add 'warn: false' to this command task or set 'command_warnings=False' in ansible.cfg to get rid of this message.
