I give again a try to bootstrap (after my last summer fail). Here how far I went: 1. Fetched the repo https://github.com/pharo-project/pharo. I have to fetch a fresh one as updating my repo failed with the git command pull/fetch/merge/reset hard does not work. Incredible how simple thinks does not work simply with git. Do people really like git or pretend to because everyone is using it. 2. Followed instructions to build a bootstrap. BUILD_NUMBER=42 BOOTSTRAP_ARCH=32 sh ./bootstrap/scripts/bootstrap.sh The resulting image bootstrap-cache/bootstrap.image is built after 1 or 2 hours. Its size is 3,4MB, when started there is only blank screen, I guess it is the expected outcome. 3. Followed instructions to load pharo environment:  BUILD_NUMBER=42 BOOTSTRAP_ARCH=32 ./bootstrap/scripts/build.sh Several attempts were needed and the build.sh script is fragile and fail when at the repeated attempts, some cleaning were needed. I suggest two things : 1. you add -p to your mkdir commands (in build.sh and get-vm.sh scripts) as it make your script less fragile ! 2. Also checking for the existence of the Pharo.source will avoid to have duplicted uncessary downloaded source file version. (Pharo.source1, Pharo.source2): if test ! -e PharoV60.sources   then       wget http://files.pharo.org/sources/PharoV60.sources fi Now the image is building, will see next.
