We are likely assuming the source image is compliant enough with the LSB[1] which references the Filesystem Hierarchy Standard[2] that specifies a /bin directory which includes the tar command[3].

Any improvement in LSB compliance would be beneficial for the UOS distribution.

I have found the cause of the problem, which is because tar does not exist in the working directory.

I wonder if there are requirements on the base image when building from the base image.

 Thank you.

Hi

We are using diskimage-builder to make a custom image, There is a problem in extract_image, The question is chroot: failed to run command 'bin/tar': No such file or directory, I found the /bin/tar file in the working directory /tmp/ tmp.00yldwe1xt. But errors are still being reported. It's not clear if this is a custom image problem, There are also requirements for custom images.
