The traceback happens when trying to print the usage for the apport command. However, the real issue is why is apport not being called correctly. Looking at a few of the crash reports we can see a pattern similar to the following: PythonArgs ['/usr/share/apport/apport', '14750', '11', '0', '1', '14750', '!opt!VBoxGuestAdditions-6.1.4!bin!VBoxClient', '(deleted)'] The "(deleted)" bit is likely coming from the %E part of the core pattern. From man core. Since kernel 5.3.0, the pipe template is split on spaces into an argument list before the template parameters are expanded. In earlier kernels, the template parameters are expanded first and the resulting string is split on spaces into an argument list. This means that in earlier kernels executable names added by the %e and %E template parameters could get split into multiple arguments. So the core dump handler needs to put the executable names as the last argument and ensure it joins all parts of the executable name using spaces. Executable names with multiple spaces in them are not correctly represented in earlier kernels, meaning that the core dump handler needs to use mechanisms to find the executable name. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apport in Ubuntu. https://bugs.launchpad.net/bugs/1884150 Title: /usr/share/apport/apport:AttributeError:/usr/share/apport/apport@424:parse_arguments:print_usage:_print_message Status in apport package in Ubuntu: New Bug description: The Ubuntu Error Tracker has been receiving reports about a problem regarding apport.
