The Cloud VPS server wlmitvisual01 under the wlm-it-visual project is still running debian-11.0-bullseye, deprecated in 2022.
As recently announced ( T428196 ) we need to migrate it to Toolforge or to a new VPS with Debian Trixie:

Debian Bullseye will reach the end of its Long Term Support(LTS) on August 31, 2026.[1]
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 the project needs to be upgraded by July 31st, 2026.
After July 31st, instances that remain on Bullseye may be subject to deprecation or cleanup efforts starting August 1st, 2026.
