Soumettre un rapport d'anomalie dans Ubuntu Server Edition

The Ubuntu Project, and thus Ubuntu Server, uses Launchpad as its bugtracker. In order to file a bug, you will need a Launchpad account. Create one here if necessary.

Reporting Bugs With apport-cli

The preferred way to report a bug is with the apport-cli command. It must be invoked on the machine affected by the bug because it collects information from the system on which it is being run and publishes it to the bug report on Launchpad. Getting that information to Launchpad can therefore be a challenge if the system is not running a desktop environment in order to use a browser (common with servers) or if it does not have Internet access. The steps to take in these situations are described below.

The commands apport-cli and ubuntu-bug should give the same results on a CLI server. The latter is actually a symlink to apport-bug which is intelligent enough to know whether a desktop environment is in use and will choose apport-cli if not. Since server systems tend to be CLI-only apport-cli was chosen from the outset in this guide.

Bug reports in Ubuntu need to be filed against a specific software package, so the name of the package (source package or program name/path) affected by the bug needs to be supplied to apport-cli: 

apport-cli PACKAGENAME

Consultez Gestion des paquets pour plus d'informations sur la gestion des paquets dans Ubuntu.

Once apport-cli has finished gathering information you will be asked what to do with it. For instance, to report a bug in vim: 

apport-cli vim

*** Collecting problem information

The collected information can be sent to the developers to improve the
application. This might take a few minutes.

*** Send problem report to the developers?

After the problem report has been sent, please fill out the form in the
automatically opened web browser.

What would you like to do? Your options are:
  S: Send report (2.8 KB)
  V: View report
  K: Keep report file for sending later or copying to somewhere else
  I: Cancel and ignore future crashes of this program version
  C: Cancel
Please choose (S/V/K/I/C):

The first three options are described below:

  • Send: submits the collected information to Launchpad as part of the process of filing a new bug report. You will be given the opportunity to describe the bug in your own words. 

    *** Uploading problem information

The collected information is being sent to the bug tracking system.
This might take a few minutes.

*** To continue, you must visit the following URL:

  https://bugs.launchpad.net/ubuntu/+source/vim/+filebug/09b2495a-e2ab-11e3-879b-68b5996a96c8?

You can launch a browser now, or copy this URL into a browser on another computer.


Choices:
  1: Launch a browser now
  C: Cancel
Please choose (1/C):  1

    The browser that will be used when choosing '1' will be the one known on the system as www-browser via the Debian alternatives system. Examples of text-based browsers to install include links, elinks, lynx, and w3m. You can also manually point an existing browser at the given URL.

  • View: displays the collected information on the screen for review. This can be a lot of information. Press 'Enter' to scroll by screenful. Press 'q' to quit and return to the choice menu.

  • Keep: writes the collected information to disk. The resulting file can be later used to file the bug report, typically after transferring it to another Ubuntu system.

Problem report file: /tmp/apport.vim.1pg92p02.apport

    To report the bug, get the file onto an internet-enabled Ubuntu system and apply apport-cli to it. This will cause the menu to appear immediately (the information is already collected). You should then press 's' to send: 

    apport-cli apport.vim.1pg92p02.apport

    To directly save a report to disk (without menus) you can do: 

    apport-cli vim --save apport.vim.test.apport
    Report names should end in .apport .

    If this internet-enabled system is non-Ubuntu/Debian, apport-cli is not available so the bug will need to be created manually. An apport report is also not to be included as an attachment to a bug either so it is completely useless in this scenario.

Faire un rapport de plantage d'une application

The software package that provides the apport-cli utility, apport, can be configured to automatically capture the state of a crashed application. This is enabled by default (in /etc/default/apport).

After an application crashes, if enabled, apport will store a crash report under /var/crash: 

-rw-r----- 1 peter    whoopsie 150K Jul 24 16:17 _usr_lib_x86_64-linux-gnu_libmenu-cache2_libexec_menu-cached.1000.crash

Use the apport-cli command without arguments to process any pending crash reports. It will offer to report them one by one. 

apport-cli

*** Send problem report to the developers?

After the problem report has been sent, please fill out the form in the
automatically opened web browser.

What would you like to do? Your options are:
  S: Send report (153.0 KB)
  V: View report
  K: Keep report file for sending later or copying to somewhere else
  I: Cancel and ignore future crashes of this program version
  C: Cancel
Please choose (S/V/K/I/C): s

If you send the report, as was done above, the prompt will be returned immediately and the /var/crash directory will then contain 2 extra files: 

-rw-r----- 1 peter    whoopsie 150K Jul 24 16:17 _usr_lib_x86_64-linux-gnu_libmenu-cache2_libexec_menu-cached.1000.crash
-rw-rw-r-- 1 peter    whoopsie    0 Jul 24 16:37 _usr_lib_x86_64-linux-gnu_libmenu-cache2_libexec_menu-cached.1000.upload
-rw------- 1 whoopsie whoopsie    0 Jul 24 16:37 _usr_lib_x86_64-linux-gnu_libmenu-cache2_libexec_menu-cached.1000.uploaded

Sending in a crash report like this will not immediately result in the creation of a new public bug. The report will be made private on Launchpad, meaning that it will be visible to only a limited set of bug triagers. These triagers will then scan the report for possible private data before creating a public bug.
