[Bug 1870060] Re: systemd ProtectSystem/mount namespace makes apport fail (impact most of our default system services)

[Brian Murray]

I had to reboot for the verification to pass, but it did.

bdmurray at clean-groovy-amd64:~$ apt list apport
Listing... Done
apport/groovy-proposed,groovy-proposed,now 2.20.11-0ubuntu50.2 all [installed,automatic]

Bug description:
  [Impact]
  apport is not creating crash files for multiple system services that use ProtectSystem since Ubuntu 20.04 LTS.

  [Test Case]
  On an Ubuntu desktop system perform the following step
  1) sudo pkill -11 upowerd

  With the current version of apport there will not be a crash file for
  upowerd in /var/crash/. With the version of apport in -proposed there
  will be a crash file for upowerd in /var/crash/.

  [Regression Potential]
  In the event that the changes to /usr/share/apport/apport are bad then apport itself would crash thereby preventing us from getting any crash reports. So in addition to killing upowerd we should also test a regular application like xeyes.

  [Original Description]
  bluetoothd never leaves dumps/crash files when it crashes

  And it seems this is true for everyone. Only supplementary binaries' crash reports are shown:
