Bug Description

[ Impact ]

The Ubuntu Error Tracker has been receiving reports about a problem regarding apport. This problem was most recently seen with package version 2.20.11-0ubuntu17, the problem page at https://errors.ubuntu.com/problem/5cc81a1cde2a921ad2adcc00e2f8d13f2c9f76e8 contains more details, including versions of packages affected, stacktrace or traceback, and individual crash reports.
If you do not have access to the Ubuntu Error Tracker and are a software developer, you can request it at http://forms.canonical.com/reports/.

As of 2022-11-24, 33,559 crashes of this type were reported in Ubuntu 18.04 (bionic).

[ Test Plan ]

Check that the fixed version does not appear on https://errors.ubuntu.com/problem/5cc81a1cde2a921ad2adcc00e2f8d13f2c9f76e8.

[ Where problems could occur ]

Worst case - in any part of the bug reporting/collection procedure, since that is what's changing.

ProcMaps contains the following, "Error: [Errno 13] Permission denied: 'maps'", when the maps file is not readable. This is not parseable by the regular expression in the function _build_proc_maps_cache, and was verified not to be parseable by the code in bionic.

So while this crash is appearing more frequently with Eoan and Focal, it is not a new crash.

This bug was fixed in the package apport - 2.20.11-0ubuntu19

---------------
apport (2.20.11-0ubuntu19) focal; urgency=medium

  * apport/report.py: do not return a duplicate signature when we are unable
    to access ProcMaps as that is necessary to create one. (LP: #1866347)
  * apport/ui.py: Always allow users to use ubuntu-bug or apport-collect
    regardless of the Problem Reporting setting as they are manually invoked
    and not automatically generated like a crash report. (LP: #1814611)

This apport bug happens very often on Ubuntu 18.04 (bionic): 87 occurrences in the past day making it on rank 4. So we should fix it in bionic.
