我启动了 Docker。

$ docker run -v /Users/ogawakiyoshi/work:/Users/ogawakiyoshi/work -it gcc /bin/bash

以下为中文语义的同义译文：

下载 Posix 测试套件 Docker 文件包，并进行 tar 解压和安装。

我用wget下载了以前写的文件。（关于那次错误的详情，请参见下一项）

# apt update; apt -y upgrade

# tar --version
tar (GNU tar) 1.30
Copyright (C) 2017 Free Software Foundation, Inc.
# tar zxvf NP_distr.Z 
tar: This does not look like a tar archive
tar: Skipping to next header
tar: Exiting with failure status due to previous errors

# tar zxvf NP_distr.Z 

gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error is not recoverable: exiting now

当在CentOS系统中执行tar命令打包时，如果出现“This does not look like a tar archive”提示，请按以下方式解决：

 

我试着解压缩了一下。

# unzip --version
caution:  both -n and -o specified; ignoring -o
UnZip 6.00 of 20 April 2009, by Debian. Original by Info-ZIP.
# unzip NP_distr.Z 
Archive:  NP_distr.Z
  End-of-central-directory signature not found.  Either this file is not
  a zipfile, or it constitutes one disk of a multi-part archive.  In the
  latter case the central directory and zipfile comment will be found on
  the last disk(s) of this archive.
unzip:  cannot find zipfile directory in one of NP_distr.Z or
        NP_distr.Z.zip, and cannot find NP_distr.Z.ZIP, period.

我尝试了在《Linux命令列表（.zip .gz .Z .bz2 tar.gz .tgz tar.Z .taz .tar.bz2 .tbz2）》（https://webkaru.net/linux/compress-uncompress-command-list/）中介绍的文件解压缩方法。

# ls
NP_distr.Z

# tar -xfZ NP_distr.Z 
tar: Z: Cannot open: No such file or directory
tar: Error is not recoverable: exiting now

# tar xfZ NP_distr.Z 
tar (child): compress: Cannot exec: No such file or directory
tar (child): Error is not recoverable: exiting now
tar: Child returned status 2
tar: Error is not recoverable: exiting now

这似乎不像是一个tar存档

# gzip --version
gzip 1.9

# gzip -dc NP_distr.Z | tar -xf -

只是更改了文件名。你能做些什么啊？

Ubuntu上使用带密码的7zip压缩工具

如果在Mac端进行文件共享并解答，则不会出错。

请使用wget。
