The code only does anything if HOME is not present. This has been in Artful and Bionic since 2016-09-16. [Other Info] Upstream merge proposal: https://code.launchpad.net/~smoser/ssh-import-id/trunk.lp1570997/+merge/326692 === End SRU Template === I've modified /usr/bin/ssh-import-id to show a stack trace rather than unhelpful message: TypeError: join() argument must be str or bytes, not 'NoneType' Then, running: $ env -u HOME ssh-import-id smoser Traceback (most recent call last): File "/usr/bin/ssh-import-id", line 62, in <module> main() File "/usr/bin/ssh-import-id", line 45, in main k = import_keys(proto, username, parser.options.useragent) File "/usr/lib/python3/dist-packages/ssh_import_id/__init__.py", line 204, in import_keys local_keys = key_list(read_keyfile()) File "/usr/lib/python3/dist-packages/ssh_import_id/__init__.py", line 135, in read_keyfile output_file = parser.options.output or os.path.join(os.getenv("HOME"), ".ssh", "authorized_keys") File "/usr/lib/python3.5/posixpath.py", line 89, in join genericpath._check_arg_types('join', a, *p) File "/usr/lib/python3.5/genericpath.py", line 143, in _check_arg_types (funcname, s.__class__.__name__)) from None TypeError: join() argument must be str or bytes, not 'NoneType' I came to find this by trying to launch an instance with: $ ec2metadata --user-data #!/bin/sh exec >/my.log 2>&1 cat /proc/uptime date -R ssh-import-id smoser The basic issue is that the environment that cloud-init runs in does not have HOME set.
