/usr/share/apport/whoopsie-upload-all:PermissionError:/usr/share/apport/whoopsie-upload-all@168:collect_info:process_report

It's the most reported 19.10 issue on e.u.c at the moment

I personally noticed this with a crash file with the following permissions:

-rw-r----- 1 bdmurray whoopsie 194K Feb 7 15:22 _usr_bin_seeded-in-ubuntu.1000.crash

whoopsie-upload-all, which runs as root, is unable to append to the crash file due to /proc/sys/fs/protected_regular being set to 1. Changing that file to 0 allows whoopsie-upload-all to run. Here's a simple test case, thanks Steve!

# echo 0 > /proc/sys/fs/protected_regular
# python3 -c "foo = open('/var/crash/_usr_bin_reportbug.1000.crash', 'ab')"
# echo 1 > /proc/sys/fs/protected_regular
# python3 -c "foo = open('/var/crash/_usr_bin_reportbug.1000.crash', 'ab')"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
PermissionError: [Errno 13] Permission denied: '/var/crash/_usr_bin_reportbug.1000.crash'

This bug was fixed in the package apport - 2.20.11-0ubuntu18

apport (2.20.11-0ubuntu18) focal; urgency=medium

  * data/whoopsie-upload-all: append to the crash report using fdopen and open
    from os to cope with protected_regular being set to 1. (LP: #1848064)

With the version of apport in -proposed we can see that crash reporting still works with /proc/sys/fs/protected_regular set to 0.

We can also see that crash reporting works with /proc/sys/fs/protected_regular set to 1.

Ok, the verification looks good. As per request I will be releasing this slightly earlier - I think 5+ days is enough of a wait anyway.

The verification of the Stable Release Update for apport has completed successfully and the package is now being released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.

This bug was fixed in the package apport - 2.20.11-0ubuntu8.5

  * Fix autopkgtest failures since recent security update: (LP: #1854237)
    - Fix regression in creating report for crashing setuid process by getting
      kernel to tell us the executable path rather than reading
      /proc/[pid]/exe.
    - Fix deletion of partially written core files.
    - Fix test_get_logind_session to use new API.
    - Restore add_proc_info raising ValueError for a dead process.
    - Delete test_lock_symlink, no longer applicable now that the lock is
      created in a directory only root can write to.
