Incident Description

A wxwidgets2.8 lucid SRU has been breaking other packages depending on it. Those needed to be rebuilt. Despite the fact that this need was identified early, the SRU reached lucid-updates.

Crisis Response Team

• Ubuntu SRU Team

Events

• 2010-07-20 Devid Antonio Filoni uploads wxwidgets2.8 2.8.10.1-0ubuntu1.1 to lucid-proposed, fixing bugs 379573 and 559822

• 2010-07-27 wxwidgets2.8 2.8.10.1-0ubuntu1.1 accepted in lucid-proposed

• 2010-07-28 pgadmin3 reported unusable for those that upgraded to lucid-proposed or maverick in bug 610975

• 2010-08-06 Thierry Carrez mentions the regression on bugs 379573 and 559822

• 2010-08-06 Devid Antonio Filoni mentions we can rebuild pgadmin3 later, after packages acceptance

• 2010-08-06 Devid Antonio Filoni uploads wxwidgets2.8 2.8.10.1-0ubuntu1.2 to lucid-proposed, re-fixing bug 559822

• 2010-08-17 wxwidgets2.8 2.8.10.1-0ubuntu1.2 accepted in lucid-proposed
• 2010-08-20 Jean-Baptiste Lallement marks 2.8.10.1-0ubuntu1.2 verification-failed due to regression
• 2010-08-22 Devid Antonio Filoni changes verification-failed to verification-done, with comment "Fix works fine. In order to fix that regression we have to rebuild pgadmin3 package, that cannot be fixed in wxwidgets2.8."
• 2010-08-24 Jean-Baptiste Lallement mentions SRU regression policy but the package was already pushed to -updates
• 2010-08-24 Martin Pitt pushes quick rebuilds for the affected packages in order to quickly fix the situation without pulling off the wxwidgets2.8 update

Successes

• Regression was identified, and the SRU bug was marked verification-failed
• Quick handling of the issue by jean-Baptiste and Martin ensured a small window of vulnerability to the issue

Problems

• The package should not have reached -updates before the corresponding needed rebuilds were ready

Recommendations

• The person who uploads the fix should not be allowed to edit verification-failed -> verification-done ?
