[Bug 1427600] Re: apport-unpack: ValueError: ['UserGroups'] has no binary content

[Launchpad Bug Tracker]

This bug was fixed in the package apport - 2.20.11-0ubuntu27.3

---------------
apport (2.20.11-0ubuntu27.3) focal; urgency=medium

  * apport_python_hook.py: if python apt modules are not built for the python
    version then do capture the crash. (LP: #1774843)
  * apport/report.py: If the user is not a part of any system groups then
    set UserGroups to 'N/A'. (LP: #1427600)

Bug description:
  [Impact]
  apport-unpack crashes when trying to unpack a crash

  [Test Case]
  On a system running 20.04 LTS:
  1) create an additional user who is only a member of their own group e.g.
  bdmurray at clean-focal-amd64:~$ id crashy
  uid=1001(crashy) gid=1001(crashy) groups=1001(crashy)
  2) Launch a process as that user
  3) kill -11 that process
  4) Confirm there is a crash file in /var/crash for that process
  5) Run apport-unpack on that .crash file

  With the version of apport from -proposed you will not get another
  crash file when unpacking the crash file.

  [Regression Potential]
  We are just setting UserGroups to 'N/A' as opposed to having it be completely empty so there isn't any chance for regression.

  When running apport-unpack to get at a core dump

  laney at raleigh> sudo apport-unpack _usr_lib_x86_64-linux-gnu_urfkill_urfkilld.0.crash ~/temp/zozoz
  [sudo] password for laney:
  Traceback (most recent call last):
    File "/usr/bin/apport-unpack", line 73, in <module>
      pr.extract_keys(f, bin_keys, dir)
    File "/usr/lib/python3/dist-packages/problem_report.py", line 253, in extract_keys
      [item for item, element in b64_block.items() if element is False])
  ValueError: ['UserGroups'] has no binary content
  laney at raleigh> apport-cli --version
  2.16.2

  It's not terrible, because most files are unpacked (those which sort
  before UserGroups, I guess).
