Summary

The standalone downloads from the Crowd website for versions 3.0.1 are gzipped twice.

The Mac version of tar will handle this without issue and a tar -zxf will work as expected. However, on linux tar will fail to unzip and untar the download.

Environment

• CentOS 7 (all linux versions most likely)

Steps to Reproduce

1. Download standalone atlassian-crowd-3.0.1.tar.gz with using Firefox
2. Attempt to extract using tar -zxf

Expected Results

File is extracted to directory.

Actual Results

$ tar -zxf atlassian-crowd-3.0.1.tar.gz
tar: This does not look like a tar archive
tar: Skipping to next header
tar: Exiting with failure status due to previous errors

Note

See Artur Pawelczyk's comment on JSWSERVER-15845.

Workaround

1. Use gunzip and then rename to get tar working:

   $ gunzip atlassian-crowd-3.0.1.tar.gz
   $ mv atlassian-crowd-3.0.1.tar atlassian-crowd-3.0.1.tar.gz
   $ tar -zxf atlassian-crowd-3.0.1.tar.gz
   

2. Use other browser to download the tar file
