Linux: Installation of extension fails with error

[yacylover]

Hi,

I'm unable to install the volumes-backup-extension. Error msg is:

[steve@cosmos volumes-backup-extension]$ docker extension install docker/volumes-backup-extension:latest Extensions can install binaries, invoke commands and access files on your machine. Are you sure you want to continue? [y/N] y Image not available locally, pulling docker/volumes-backup-extension:latest...

I also tried to build from source but with the same error. Kernel boot arg overlay.metacopy=N or echo N | sudo tee /sys/module/overlay/parameters/metacopy
doesn't help :-(

Hi @yacylover, thanks for reporting this issue.

We're aware of it and we'll be releasing a fix in the next release of Docker Desktop (4.18).
