Phased updates can cause build regressions on Ubuntu Jammy #670
Comments
See: ros-infrastructure/ros_buildfarm#969 And discussion on event happening: https://osrf.slack.com/archives/C5UEHBHD2/p1659110534293569 |
Last week we had an issue related to this. The issue is not related necessarily with phased updates but rather with how phased updates work vs our current workflow with docker. |
Bug Report Track
Phased updates are available on
apt
since Ubuntu 21.04. This has caused build regressions events on our buildfarms at ci.ros2.orgPhased updates knowledge base:

Events
June 7th, first time appearance,
Linux CI was totally broken for that day

Fix for the problem: #667
June 21st, second time appearance,
Linux CI was partially affected, the problem "fixed itself" and there was no CI downtime because the nodes were using the ccache.
This wasn't expected to occur because with the previously attached PR we opted out of phased updates.
