I suggest you to stop using evilsperm's VM wich seems to be outdated. Latest pre-compiled PSL1GHT environnement : Precompiled PSL1GHT (v2) for Linux x86_64 (64bits) : psl1ght-v2-x86_64.tar.bz2 (MD5 : a78fb73f2ee60b3344ad5fe4edf9467f) Source : http://ps3devwiki.com/wiki/PSL1GHT But the best way, if you do not want to install GNU/Linux on your PC, is to create yourself a VM with the latest debian stable and follow these instructions : http://psl1ght.net/wiki/TutorialInstall:Debian If you want to update PSL1GHT : http://www.psxbrew.net/wiki/Update_PSL1GHT Use the official GIT repository wich includes @deroad 's commits (Jul 08, 2012 - Jul 18, 2012) : https://github.com/ps3dev ps : Your problem is a user rights issue, use the command sudo or execute it under root access (su -).
