I just downloaded the ISO from
http://sarkpbx.com/twiki/bin/view/Main/DownLoadPages.
After mounting the ISO, the Sail RPM is 2.2.4-8.
Now I may be wrong, but on this same exact machine I installed SME 7.4 with no problem (yesterday) and SME 8.0b4 (also yesterday).
The SARK DEMO ISO crashed during package installation.
So, what does all that mean? My guess is my hardware is OK, since I did try NEW MEMORY (same problem) and NEW HARD DRIVE (same problem).
Since there is no MD5sum for it, I double checked by downloading the ISO once again and comparing it to the first one I downloaded. NO DIFFERENCES ENCOUNTERED.
That's it... I can't do any more.
