tar -xvf file.tar.gz失败，原因是：gzip：stdin：not in gzip format

Question

我用命令tar压缩了一组文件：tar -czvf file.tar.gz file/然后复制到usb（ext4格式），我检查了是否可以解压缩它。重新安装系统后，在挂载usb时发生了一些错误，我fsck /dev/sdc1成功安装了并将其复制到pc。当我解压缩它时tar -xvf file.tar.gz，错误再次发生：

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

我不知道如何挽救数据。需要任何帮助。谢谢。

Answer 1

@sitexa , I got this error when file is not fully downloaded(transferred).

tar xvfz apache-tomcat-8.5.12.tar.gz
gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error is not recoverable: exiting now

This error is coming due to file is not completely downloaded.
