@pyama86 Thank you for your feedback. I could not reproduce it in my environment. Please let me know your OS/ARCH and the result of the following command.

$ docker image ls --no-trunc ubuntu:latest

[pyama86]

# docker image ls --no-trunc ubuntu:latest
REPOSITORY   TAG       IMAGE ID                                                                  CREATED      SIZE

As shown above. Recently, there have been issues that started occurring after updating to the latest version of Docker due to a vulnerability in runc. Therefore, there might be some relation to Docker.

# docker -v
Docker version 25.0.2, build 29cf629

@pyama86 Thank you for the information. This bug may have been addressed in the latest version. I hope testing it in your environment to confirm.
