- == Fixed ==
-  * '''[fixed in dapper-updates and Edgy]''' Crash if /boot is on XFS: [[https://launchpad.net/bugs/47848|Bug 47848]]
- 
-  This can be recognised by grub-installer exiting 10 or 30, and /var/log/partman or /var/log/installer/syslog (look for "mountpoints:" in the latter) indicating that / is on XFS and there is no non-XFS /boot filesystem. Feel free to mark such bugs as duplicates of #47848, with text such as: {{{
- Thanks for your report. Due to some reliability problems with GRUB and XFS, you need to use a non-XFS root filesystem or create a non-XFS /boot filesystem. The fact that the partitioner doesn't warn you about this up-front is also bug 47848, and is fixed in 6.06.1.
- }}}
- 
-  * '''[fixed in dapper-updates and Edgy Knot 1]''' Crash if system partitions are not reformatted: [[https://launchpad.net/bugs/47046|Bug 47046]]
- 
-  This can be recognised by an OS``Error exception being thrown from the `copy_all` function, usually "File exists" or similar, and a "mountpoints:" line in /var/log/installer/syslog that includes a tuple with a standard filesystem (e.g. /, /boot, /usr, or /var; not /home or /media/*) as the first item and False as the second item. Feel free to mark such bugs as duplicates of #47046, with text such as: {{{
- Thanks for your report. At present, you must reformat system partitions (e.g. /, /boot, /usr, or /var) during installation; the fact that the partitioner doesn't warn you about this is also bug 47046, and is fixed in 6.06.1. If you are upgrading an existing installation, then please see http://wiki.ubuntu.com/DapperUpgrades rather than using this installer.
- }}}
- 
-  * '''[fixed in dapper-updates and Edgy]''' Crash if some packages on running live session are unconfigured: [[https://launchpad.net/bugs/47859|Bug 47859]]
- 
-  This can be recognised by a dpkg error in /var/log/installer/syslog while installing language packs, and a crash in the `install_language_packs` function. Feel free to mark such bugs as duplicates of #47859, with text such as: {{{
- Thanks for your report. This is also bug 47859, and can be worked around by not installing [substitute the package that broke here] in the live session before running the installer. This is fixed in 6.06.1.
- }}} If one of the packages that broke was `ntp`, then use the following text: {{{
- Thanks for your report. This is also bug 47859, and can be worked around by not choosing to install NTP support while running the installer. It can be installed after rebooting into the newly-installed system by right-clicking on the date/time applet and selecting "Adjust Date & Time". This is fixed in 6.06.1.
- }}}
- 
-  * '''[fixed in dapper-updates and Edgy Knot 1]''' Crash when installing in Chinese but with a non-Chinese-speaking country: [[https://launchpad.net/bugs/47687|Bug 47687]]
- 
-  This can be recognised by Chinese characters scattered through /var/log/installer/syslog and: {{{
- ubiquity: ['sh', '-c', '/usr/lib/ubiquity/localechooser/post-base-installer && /usr/lib/ubiquity/localechooser/prebaseconfig'] exited with code 1
- }}} Feel free to mark such bugs as duplicates of #47687, with text such as: {{{
- Thanks for your report. This is also bug 47687, and occurs when you select a Chinese language (either Simplified or Traditional) but then select a non-Chinese-speaking country on the timezone/country selection page. This is fixed in 6.06.1, so you can work around it by upgrading all packages with 'ubiquity' in their names on the running live CD before starting the installer.
- }}}
- 
- 
-  * '''[fixed in dapper-updates and Edgy Knot 1]''' Crash with certain kinds of disk attached: [[https://launchpad.net/bugs/48732|Bug 48732]]
- 
-  This can be recognised by the following at the end of the traceback (ignoring line and byte number differences): {{{
-   File "/usr/lib/python2.4/site-packages/ubiquity/components/partman.py", line 214, in run
-     if not self.frontend.set_disk_choices(self.choices(question),
-   File "/usr/lib/python2.4/site-packages/ubiquity/filteredcommand.py", line 189, in choices
-     choices = unicode(self.db.metaget(question, 'choices'), 'utf-8')
- UnicodeDecodeError: 'utf8' codec can't decode bytes in position 204-205: invalid data
- }}} Feel free to mark such bugs as duplicates of #48732, with text such as: {{{
- Thanks for your report. This is also bug 48732, and occurs due to strange model names on certain disks. This is fixed in 6.06.1, so you can work around it by upgrading all packages with 'ubiquity' in their names on the running live CD before starting the installer.
- }}}
- 
-  * '''[fixed in dapper-updates and Edgy Knot 1]''' Crash when gparted crashes: [[https://launchpad.net/bugs/48856|Bug 48856]]
- 
-  This can be recognised by the following at the end of the traceback: {{{
-     print >>self.gparted_subp.stdin, "apply"
- AttributeError: 'NoneType' object has no attribute 'stdin'
- }}} Feel free to mark such bugs as duplicates of #48856, with text such as: {{{
- Thanks for your report, which is also bug 48856. The program used for advanced partitioning, gparted, appears to have crashed. The version of the installer present in Ubuntu/Edubuntu/Xubuntu 6.06.1 deals with this more gracefully. If you can reproduce the gparted crash by running it directly from the System -> Administration menu, then please file a separate bug against gparted.
- }}}
- 
-  * '''[fixed in dapper-updates and Edgy Knot 1]''' Crash when qtparted crashes: [[https://launchpad.net/bugs/47194|Bug 47194]]
- 
-  This can be recognised by the following at the end of the traceback: {{{
-     print >>self.qtparted_subp.stdin, "apply"
- AttributeError: 'NoneType' object has no attribute 'stdin'
- }}} Feel free to mark such bugs as duplicates of #47194, with text such as: {{{
- Thanks for your report, which is also bug 47194. The program used for advanced partitioning, qtparted, appears to have crashed. The version of the installer present in Kubuntu 6.06.1 deals with this more gracefully. If you can reproduce the qtparted crash by running it directly from K Menu -> System, then please file a separate bug against qtparted.
- }}}
- 
-  * '''[fixed in dapper-updates and Edgy Knot 1]''' Crash when hw-detect fails to load a module: [[https://launchpad.net/bugs/48524|Bug 48524]]
- 
-  This can be recognised by the following in `/var/log/installer/syslog` just before the traceback: {{{
- ubiquity: ['/bin/hw-detect'] exited with code 1
- }}} (AND ONLY THAT EXIT CODE!) and the following as the last message about `hw-detect` in `/var/log/syslog`: {{{
- Aug 24 18:02:10 ubuntu hw-detect: Detecting hardware...
- }}} Feel free to mark such bugs as duplicates of #48524, with text such as: {{{
- Thanks for your report. This is also bug 48524, and occurs due to a failure to handle module load errors on certain hardware. This is fixed in 6.06.1, so you can work around it by upgrading all packages with 'ubiquity' in their names on the running live CD before starting the installer.
- }}}
- 
-  * '''[fixed in Feisty Herd 2]''' Crash if language packs are uninstallable in certain ways: [[https://launchpad.net/bugs/61912|Bug 61912]]
- 
-  This can be recognised by the following traceback from `install.py` (in 6.06, you'll need to look in `/var/log/installer/syslog`): {{{
-   File "/usr/share/ubiquity/install.py", line 1347, in ?
-     install.run()
-   File "/usr/share/ubiquity/install.py", line 335, in run
-     self.install_language_packs()
-   File "/usr/share/ubiquity/install.py", line 807, in install_language_packs
-     self.mark_install(cache, lp)
-   File "/usr/share/ubiquity/install.py", line 734, in mark_install
-     assert cache._depcache.BrokenCount == 0
- AssertionError
- }}} If `self.mark_install` is not present in the traceback, then it is a different bug. Otherwise, feel free to mark such bugs as duplicates of #61912, with text such as: {{{
- Thanks for your report. This is also bug 61912, and occurs due to a failure to handle uninstallable language packs. You can typically work around this by installing in English or by disconnecting from the network during installation.
- }}}
- 
-  * '''[fixed in Hardy Heron]''' Crash when autopartitioning and disk is too small: [[https://launchpad.net/bugs/48355|Bug 48355]]
- 
-  This can be recognised by {{{IOError: [Errno 28] No space left on device}}} being thrown inside the `copy_all` function, and `stepPartAdvanced` not appearing in /var/log/installer/syslog; also check the end of /var/log/partman to make sure that the size of the disk is smaller than about 2.5GB (I'm not sure of the exact figure). Feel free to mark such bugs as duplicates of #48355, with text such as: {{{
- Thanks for your report. I'm afraid that one of your partitions seems to be too small to complete an Ubuntu desktop installation successfully. Bug 48355 notes that the partitioner should have warned you about this. This has been fixed in Hardy Heron.
- }}}
- 
-  * '''[fixed in Hardy Heron - ubiquity version 1.7.9]''' Ubiquity dialogs too large for 800x600 display: [[https://launchpad.net/bugs/38442|Bug 38442]]
- 
-  The timezone map used in ubiquity was a static size and larger than 800x600 so it was challenging to use ubiquity with hardware that would use a display resolution lower than that.  It is possible that some duplicate bug reports still exist and they should be marked as a duplicate of 38442 with text such as: {{{
- Thanks for taking the time to report this bug and helping to make Ubuntu better.  This bug is a duplicate of bug 38442 and is being marked as such.  Incidentally, this issue is resolved in Hardy Heron as the timezone map can scale down to 674x434. 
- }}}
- 
-  * '''[fixed in Hardy Heron ]''' Login sound plays while installing from the Live CD [[https://launchpad.net/bugs/178057|Bug 178057]]
- 
-  During the installation process the login sound was being played multiple times.  This was not strictly a ubiquity bug but rather a bug in debian-installer-utils.  However, most of the bug reports about it will be filed about ubiquity.
