I installed the version of apport from xenial-proposed and no longer received a Traceback when running the test case.

The problematic change is the dropping of supplemental groups in data/apport. This results in a PermissionError as it is not the root user who is calling /usr/share/apport/apport. [Test Case] The least convulted test case involves using the generate-sigsegv-crash.py script from apport-test-crashes. This ends up using a command similar to '/usr/share/apport/apport -p 4077 -s 11 -E /usr/bin/gnome-calculator < /tmp/20.10-gnome-calculator.core' which then will encounter the Traceback. 1) Comment out "check_lock()" in /usr/share/apport/apport (This is necessary as we are not running as root) 2) Put a copy of generate-sigsegv-crash.py on disk. 3) Run 'python3 /tmp/generate-sigsegv-crash.py cat' 4) Observe the following Traceback: Traceback (most recent call last): File "/tmp/tmpvkt5d266/apport", line 599, in <module> drop_privileges(True) File "/tmp/tmpvkt5d266/apport", line 125, in drop_privileges os.setgroups([]) PermissionError: [Errno 1] Operation not permitted With the version of apport from -proposed you'll receive no such Traceback. [Regression Potential] If there is an error in the python code we code see a new traceback for any and all crashes being generated, so ensure regular crash generation works too. apport-test-crashes code is here: https://code.launchpad.net/~daisy-pluckers/error-tracker-deployment/test-crashes/ To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apport/+bug/1906565/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
