Autopsy 3.x is a Windows only release at this point. This package is an effort at troubleshooting linux issues.

The Autopsy Forensic Browser is a graphical interface to the command line
digital forensic analysis tools in The Sleuth Kit. Together, The Sleuth Kit and
Autopsy provide many of the same features as commercial digital forensics tools
for the analysis of Windows(tm) and UNIX file systems (NTFS, FAT, FFS, EXT2FS,
and EXT3FS).

The Sleuth Kit and Autopsy are both Open Source and run on UNIX platforms. As
Autopsy is HTML-based, the investigator can connect to the Autopsy server from
any platform using an HTML browser. Autopsy provides a "File Manager"-like
interface and shows details about deleted data and file system structures.
