[Bug 2049907] Re: tracker-extract-3 crash with SIGSYS when upgrading from 22.04 to 24.04

[Brian Murray]

This is failing to retrace due to the fact that there are mixture of
packages from Noble and Jammy. It'd be interesting to look at the
timestamp of the crash versus where we were in the upgrade process but I
suspect it was somewhere in the middle.  Subsequently, I think we should
probably just turn off whatever runs tracker-extract while the upgrade
is in progress. (There is code in ubuntu-release-upgrader to do similar
things.)

Here's part of apport's output:

Title:
  tracker-extract-3 crashes routinely during distribution upgrades

Status in tracker-miners package in Ubuntu:
  New
Status in ubuntu-release-upgrader package in Ubuntu:
  New

Bug description:
  Very similar behavior as this existing bug:
  https://bugs.launchpad.net/ubuntu/+source/tracker-miners/+bug/1983859

  Almost copy-paste of original report:

  When upgrading Ubuntu Desktop from 22.04 to 24.04, there's often
  (pretty much always) a crash from tracker-extract, as described in the
  following error report:

  https://errors.ubuntu.com/oops/7a86fbf0-b52b-11ee-b9e4-fa163e171f02

  The crash occurs during the upgrade, which means it's fairly hard to
  investigate exactly what's going on as apport fails to extract a stack
  trace, the binaries being overwritten during the upgrade.
