tl;dr: We will likely downgrade
arm32 on Ubuntu Focal support to Tier 3 for Foxy.
As we approach the release of Foxy Fitzroy in three weeks, we have identified an unexpected backlog of effort related to supporting 32-bit ARM platforms (
arm32) for Ubuntu Focal. Our intent for Foxy, as written in REP-2000, has been to keep Ubuntu Focal on
arm32 as a Tier 2 supported platform, and to upgrade its support by officially adding binary
.deb packages. But as we prioritize finishing the Foxy release, QA, and testing work for the Tier 1 platforms, at this point it seems likely that we will not be able to address the current open issues on
arm32. As a result we expect to downgrade Ubuntu Focal
arm32 from Tier 2 to Tier 3 for Foxy.
Based on the usage data we have available, we expect this change to affect a small minority of users. If you are one of them, please let us know.
Apologies for the late notice.
