Can't extract latest civicrm-4.7.22-drupal.tar.gz to install
I tested those two downloads, and found:


The two tar.gz files are identical (MD5=26e2db3c52d105659acc293cc2ffc74c for civicrm-4.7.22-drupal.tar.gz)
Yes, there's an invalid symlink in the file.


That "bad" symlink might offend some tools (and might trigger anti-virus warnings) but it's harmless and should not affect the CiviCRM files you've downloaded. It links a README in one of our packages from that package's docs dir to the package root, and we strip that docs folder out of the code we ship.

I have opened an issue (CRM-20884) &amp; submitted a small fix (PR10676) to resolve that missing symlink in some upcoming release.

Thanks for raising this! You did the right thing to question what you were seeing. FWIW, I recommend downloading from https://civicrm.org/download in favour of SourceForge.
