Description
I installed following your procedure, but when I tried to install sleuthkit-java_4.6.0-1_amd64.deb I got an error. If I try to launch Autopsy sh ./autopsy I got an error, it cannot find the sluethkit-4.6.0.jar file: ERROR: /usr/share/java/sleuthkit-4.6.0.jar not found, please install the sleuthkit-java_4.6.0-1_amd64.deb file.
So, I used Engrampa Archive Manager and I extract the file inside the sleuthkit-java_4.6.0-1_amd64.deb into the matching directories of my system (e.g. /usr/share/java, etc.) then when I ran ./autopsy it worked!
For working on local disk, you can simply run sudo ./autopsy
That's all.
Finally the problem is only with the sleuthkit-java_4.6.0-1_amd64.deb
PS.1: If you get this error: ERROR: JAVA_HOME environment variable must be defined You can logout then login in your system and the variable is set or try to write export JAVA_HOME, as written by DKARPO in this issues repo.
PS.2: Autopsy for Linux seems faster than for Windows ;-)
