[Bug 1821415] Re: pkexec fails in a non-graphical environment

[Launchpad Bug Tracker]

This bug was fixed in the package apport - 2.20.11-0ubuntu50.6

---------------
apport (2.20.11-0ubuntu50.6) groovy; urgency=medium

  * data/general-hooks/ubuntu.py: tag bugs from Raspberry Pi images and RISCV
    images appropriately. (LP: #1920837)
  * apport/hookutils.py: spawn pkttyagent so that log files can be gathered as
    root in a non-graphical environment (LP: #1821415). Thanks to Iain Lane
    for the patch.
  * apport/hookutils.py: root access is needed to read the
    casper-md5check.json file so switch to using that. (LP: #1922937)

Bug description:
  [Impact]
  The plymouth apport source package hooks wants to gather log files as the root user and apport provides a policy kit policy for collecting that information. This works fine in a graphical environment but not in a non-graphical one.

  [Test Case]
  1) ssh into an Ubuntu Desktop install of Ubuntu 20.04 LTS or Ubuntu 20.10
  2) sudo touch /var/log/plymouth-debug.log
  3) ubuntu at disco:~$ ubuntu-bug plymouth

  *** Collecting problem information

  The collected information can be sent to the developers to improve the
  application. This might take a few minutes.
  ..........==== AUTHENTICATING FOR com.ubuntu.apport.root-info ===
  Authentication is required to collect system information for this problem report
  Authenticating as: Ubuntu (ubuntu)

  polkit-agent-helper-1: error response to PolicyKit daemon: GDBus.Error:org.freedesktop.PolicyKit1.Error.Failed: No session for cookie
  ==== AUTHENTICATION FAILED ===
  Error executing command as another user: Not authorized

  This incident has been reported.

  With the version of apport from -proposed you will not see the
  "AUTHENTICATION FAILED" error and the plymouth-debug.log file will be
  collected.

  [Where Problems Could Occur]
  It's possible that the spawned pkttyagent process does not get cleaned up properly and could be left running. When testing the SRU we should confirm it is not still running.
