Unable to start up docker stack past v1.92.2

[matrixbot]

This issue has been migrated from #16716.

---

Description

When upgrading, it doesn't look like we're able to upgrade pass v1.92.1, since v1.92.2 is now using debian bookworm. Under bookworm, we're seeing this issue when we try to run the stack: docker-library/python#835

Would it be possible to add a -bullseye specific docker image release for newer versions, until the upstream Docker issue is resolved?

Anything else that would be useful to know?

We saw this exact issue with another one of our service: OrcaCollective/OpenOversight#332

[antonok-edm]

looks like there are some comments on the original issue that didn't make it back here...

As another data point in support of "update the packages on the host", I encountered this issue running the Docker container on Alpine 3.13, but updating again to Alpine 3.14 resolved it.
