To all Singularity users,
On Tuesday September 12, Docker released a new version of Docker image metadata. This means that any new images built on Docker Hub cannot currently be downloaded using a singularity
pull or other commands like
bootstrap when updated Docker registries are queried.
@v) has created an interim fix for the problem and we have merged it into the development branch. Pending further testing we plan to merge this fix into master and create a new minor release (2.3.2). We will make another announcement as soon as it is ready to install.
Thanks for your patience!
The Singularity team
