Classifying ubiquity bugs as duplicates can be difficult because similar tracebacks can have many different causes resulting from different hardware or configuration. It generally necessary to examine the syslog and partman files to fine the exact cause of a crash and this may need to be done by a developer.

To help the process along we can list candidates for duplication on this page and gather data about them to build a case for merging them in each category.

ValueError: invalid literal for int():

Example: https://launchpad.net/distros/ubuntu/+source/ubiquity/+bug/53783

Seen in versions: Dapper and earlier

Notes: Most of these bugs have had their titles changed to 'debconf frontend went away'. These are *not* firm duplicates, but they share the line ValueError: invalid literal for int(): at the end of their traceback

Triaging plan: Many of these bugs do not have useful logs, and most look unlikely to get them (after repeated requests). It is normally not advisable to mark as duplicate duplicate bugs where the cause is not fully understood. In this case we plan to group the reports that have the same traceback, that do not have logs and look unlikely to get them. This move has been cleared with the package maintainer, as should be cone in such cases. The reason for grouping them will also be marked clearly.
