How to extract filename.tar.gz file

Question

I want to extract an archive named filename.tar.gz.

Using tar -xzvf filename.tar.gz doesn't extract the file. it is gives this error:

gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error exit delayed from previous errors

Answer 1

Check to make sure that the file is complete. This error message can occur if you only partially downloaded a file or if it has major issues. Check the MD5sum.
