Hi, could you add a line in the main post about the python script requiring at least 150 MB free space in userspace? After mysterious "package script failed (1)" errors from MRInstaller and "Hu oh... Got return code 1 . . .

" messages in mrinstaller.log, I trawled through these forums and was in the middle of composing a long error report when I noticed the install.sh and the 150 MB requirement in it. Noticing I had only 140 MB or so, I tried freeing up some more and voila, installed flawlessly.
Given the puny 2GB of PW, it's easy to fill it up leaving too little space; so, just a mention of this in the original post would help people check for this as a possible source of error.
