<title>Reporting Bugs in Ubuntu Server Edition</title>
19
While the Ubuntu Project attempts to release software with as few
20
bugs as possible, they do occur. You can help fix these bugs by
21
reporting ones that you find to the project. The Ubuntu Project
22
uses <ulink url="https://launchpad.net/">Launchpad</ulink>
23
to track its bug reports. In order to file a bug
24
about Ubuntu Server on Launchpad, you will need to

<title>Reporting Bugs With ubuntu-bug</title>
33
The preferred way to report a bug is with the
34
<application>ubuntu-bug</application> command. The ubuntu-bug
35
tool gathers information about the system useful to developers in
36
diagnosing the reported problem that will then be included in the
37
bug report filed on Launchpad. Bug reports in Ubuntu need to be
38
filed against a specific software package, thus the name of the
39
package that the bug occurs in needs to be given to ubuntu-bug:
43
<command>ubuntu-bug PACKAGENAME</command>
47
For example, to file a bug against the openssh-server package, you would do:
51
<command>ubuntu-bug openssh-server</command>
55
You can specify either a binary package or the source package
56
for ubuntu-bug. Again using openssh-server as an example,
57
you could also generate the report against the source package
58
for openssh-server, openssh:
62
<command>ubuntu-bug openssh</command>
67
See <xref linkend="package-management"/>
68
for more information about packages in Ubuntu.
73
The ubuntu-bug command will gather information about the system in
74
question, possibly including information specific to the specified
75
package, and then ask you what you would like to do with collected
80
<command>ubuntu-bug postgresql</command>
82
*** Collecting problem information
84
The collected information can be sent to the developers to improve the
85
application. This might take a few minutes.
88
*** Send problem report to the developers?
90
After the problem report has been sent, please fill out the form in the
91
automatically opened web browser.
93
What would you like to do? Your options are:
94
S: Send report (1.7 KiB)
96
K: Keep report file for sending later or copying to somewhere else
98
Please choose (S/V/K/C):

The options available are:

Send Report submits the collected information to Launchpad as
110
part of the the process of filing a bug report. You will be
111
given the opportunity to describe the situation that led up to
112
the occurrence of the bug.
116
*** Uploading problem information
118
The collected information is being sent to the bug tracking system.
119
This might take a few minutes.
122
*** To continue, you must visit the following URL:

136
If you choose to start a browser, by default the text based web
137
browser <application>w3m</application> will be used to finish filing
138
the bug report. Alternately, you can copy the given URL to a

currently running web browser.

After viewing the report, you will be brought back to the same

<emphasis role="bold">Keep Report File</emphasis> Selecting Keep
176
Report File causes the gathered information to be written to
177
a file. This file can then be used to later file a bug report
178
or transferred to a different Ubuntu system for reporting.
179
To submit the report file, simply give it as an argument to
180
the ubuntu-bug command:

<title>Reporting Application Crashes</title>
213
The software package that provides the ubuntu-bug utility,
214
<application>apport</application>, can be configured to trigger
215
when applications crash. This is disabled by default, as capturing
216
a crash can be resource intensive depending on how much memory
217
the application that crashed was using as apport captures and
218
processes the core dump.
222
Configuring apport to capture information about
223
crashing applications requires a couple of steps. First,
224
<application>gdb</application> needs to be installed; it is not
225
installed by default in Ubuntu Server Edition.
229
<command>sudo apt-get install gdb</command>
233
See <xref linkend="package-management"/>
234
for more information about managing packages in Ubuntu.
238
Once you have ensured that gdb is installed, open the file
239
<filename>/etc/default/apport</filename> in your text editor,
240
and change the <emphasis>enabled</emphasis> setting to be
241
<emphasis role="bold">1</emphasis> like so:
245
# set this to 0 to disable apport, or to 1 to enable it
246
# you can temporarily override this with
247
# sudo service apport start force_start=1
248
enabled=<userinput>1</userinput>
250
# set maximum core dump file size (default: 209715200 bytes == 200 MB)
255
Once you have completed editing
256
<filename>/etc/default/apport</filename>,
257
start the apport service:
261
<command>sudo start apport</command>
265
After an application crashes, use the
266
<application>apport-cli</application> command to search for the
267
existing saved crash report information:
271
<command>apport-cli</command>
273
*** dash closed unexpectedly on 2010-03-11 at 21:40:59.

If you were not doing anything confidential (entering passwords or other
276
private information), you can help to improve the application by
280
What would you like to do? Your options are:
282
I: Cancel and ignore future crashes of this program version
284
Please choose (R/I/C):
288
Selecting <emphasis>Report Problem</emphasis> will walk you through
289
similar steps as when using ubuntu-bug. One important difference
290
is that a crash report will be marked as private when filed on
291
Launchpad, meaning that it will be visible to only a limited set
292
of bug triagers. These triagers will review the gathered data for private
293
information before making the bug report publicly visible.
296
<!-- Include a bit here on using apport-retrace for generating a
297
full stack trace locally, for situations when the application
298
does contain confidential information that should not be
299
submitted to launchpad? -->
