docker load cannot load xz archive files

[mbengit]

Executing docker load < archive.xz on the command line produces this error:

exec: "xz": executable file not found in $PATH

This issue was introduced in Docker Desktop 3.1.0 and is easily reproducible on MacOS and Windows.

• I have tried with the latest version of Docker Desktop
• I have tried disabling enabled experimental features
• I have uploaded Diagnostics

It seems likely that the new Debian container added in 3.1.0 does not support xz.

[stephen-turner]

Yes, it could be that. @simonferquel PTAL.

Hi, is there any progress on a fix for this issue?
I work on a product which depends on being able to load an xz-archived image to the local docker registry, so this issue has a sizeable impact.

Hi, the fix will be available in the next release.

Hi @mat007,

Could you tell me when is planned the next release?
I am also impacted by this issue.

Thank you!

[stephen-turner]

Sorry, we don't have a firm date yet, but it will probably be towards the end of this month.

[qalinn]

@stephen-turner That means days, weeks, months? Or how does it release a new version?

[stephen-turner]

Definitely weeks, not days or months.

[qalinn]

@stephen-turner Thank you

As a workaround, you can use buildx and the default moby/buildkit:buildx-stable-1 image which appears to still hve xz in it, i.e.:

$ docker buildx create --driver docker-container --name fix-xz --use
$ docker buildx build --load -t image:tag .
