I tested this in an Ubuntu 18.04 lxc container and removed the policykit-1 package. With the version of apport in -updates I received the Traceback which appears in the bug description. After that I installed the version of apport from -proposed and I did not receive a Traceback.

This was worked around in Ubuntu 19.10 by not gathering any information that would require root access. Test Case --------- 1) Install multipass. 2) `multipass launch http://cloud-images.ubuntu.com/minimal/daily/bionic/current/bionic-minimal-cloudimg-amd64.img -n reproducer` 3) `multipass shell reproducer` 4) `ubuntu-bug cloud-init` Expected behaviour: Usual bug reporting flow (though, currently, I would really expect to see just the issue reported in bug 1861450). Actual behaviour: ERROR: hook /usr/share/apport/package-hooks/cloud-init.py crashed: Traceback (most recent call last): File "/usr/lib/python3/dist-packages/apport/report.py", line 198, in _run_hook symb['add_info'](report, ui) File "/usr/share/apport/package-hooks/cloud-init.py", line 6, in add_info return cloudinit_add_info(report, ui) File "/usr/lib/python3/dist-packages/cloudinit/apport.py", line 123, in add_info attach_cloud_init_logs(report, ui) File "/usr/lib/python3/dist-packages/cloudinit/apport.py", line 57, in attach_cloud_init_logs 'cloud-init-output.log.txt': 'cat /var/log/cloud-init-output.log'}) File "/usr/lib/python3/dist-packages/apport/hookutils.py", line 444, in attach_root_command_outputs sp = subprocess.Popen(_root_command_prefix() + [wrapper_path, script_path]) File "/usr/lib/python3.6/subprocess.py", line 729, in __init__ restore_signals, start_new_session) File "/usr/lib/python3.6/subprocess.py", line 1364, in _execute_child raise child_exception_type(errno_num, err_msg, err_filename) FileNotFoundError: [Errno 2] No such file or directory: 'pkexec': 'pkexec' (As alluded to above, this also demonstrates bug 1861450 after the traceback is emitted.) Regression Potential -------------------- Little as we are just returning and empty list if pkexec is not available, however it is always possible that the code is misformated or that there is a logic error in it. A regression test would be to run the ubuntu-bug cloud-init on a system with pkexec installed.
