Error executing oz install in ARM architecture environment

[gastanki]

English is not my native language, please forgive me.

When I installed oz through the master branch in the ARM architecture, everything went smoothly at first until I executed the command;
The command I am executing is oz-install -a centos76.auto -d 4 centos76.tdl .
Error message:Fedora/Red Hat installs can only be done using a boot. iso (netinst) or DVD image (LiveCDs are not Supported) .

I conducted an investigation and found that the problem lies in the Guest.py file_ Copy_ Iso function;

At present, it seems that oz itself has put iso into the fds device;guestfs_ tar_ out function decompresses it to iso_contents path;However, the decompressed data is not complete.
I am interested in_ copy_ Iso function break point;guestfs_ tar_ out function runs normally and exits execution;

I executed the mount command to mount ISO, but did not find any file loss, which means my ISO file is complete;

How to continue troubleshooting incomplete decompression iso of thisguestfs_ tar_ out function.
