Contact maintainers of Cloud VPS projects with instances still running Debian Bullseye to migrate to a supported operating system.
List of projects(79 in all) as at June 4th, 2026
+++++ Message +++++++
Hello <Admin>,
We are reaching out to you because you are listed as an admin of the Cloud VPS <projects> below.
Some VMs in your project are still running on Debian Bullseye[0].
The migration from Debian Bullseye has been underway across Cloud VPS projects for a while now, and most affected projects have already completed their migrations.
Debian Bullseye will reach the end of its Long Term Support(LTS) on August 31, 2026.
In order to keep our platforms secure we need to move to Debian Bookworm or Trixie.
As part of this migration, it may be worth evaluating whether your workload is a good fit for Toolforge.
If feasible, migrating to Toolforge can reduce future maintenance burden, as operating system upgrades are handled by the platform.
All affected instances in these projects need to be upgraded by July 31st, 2026.[1]
After July 31st, instances that remain on Bullseye may be subject to deprecation or cleanup efforts starting August 1st, 2026.
<List of projects>
If you have already migrated your project, thank you!
Please reach out for help if you're unclear what this means, or how to upgrade[2].
