Status changed to 'Confirmed' because the bug affects multiple users.

[Dmitry Shachnev (mitya57)]

Hi!

Do you have a file in /var/crash? Can you run ubuntu-bug command and pass that file as an argument?

[Valentyna (valia0906)]

I have file and run command, send bug report maybe this needed
# cat _usr_bin_gnome-flashback.1000.uploaded
0b68a1cc-0c76-11ef-8b36-fa163ec8ca8c

[Dmitry Shachnev (mitya57)]

Thank you. Unfortunately your report was not processed because you have not all updates installed (in particular, distro-info-data is old).

Can you install all updates and try again please?

[Valentyna (valia0906)]

I have installed all updates and send report again
/var/crash# cat _usr_bin_gnome-flashback.1000.uploaded

[Dmitry Shachnev (mitya57)]

Unfortunately, it still thinks that your distro-info-data is too old.

Can you try to run the command provided by Alberts in the upstream bug?

[Valentyna (valia0906)]

I have done apport-retrace and wrote it to file
