Hi guys, Updating Pharo from the update stream failed many times and keep on failing for me... But maybe it's just me... So I picked the unstable link from the web site (http://www.pharo-project.org/pharo-download/unstable-core) This drives me to a 13091 image. The first thing I do is select the 'update system' menu... Err, it fails... It seems related to broken sources... Well the image points to which source file ? can't remember the incantation, let just browse it... Err, no source, I can't browse. No matter, I set the browser to decompile mode... Err, this does not work, I still can't browse code. Hmm very bad starting experience, I know what unstable means, but I was dreaming of other words like continuous development. So ket's open an older image (my own updated 1.2) to find the incantations. (Scanner>>#scanTokens:) fileIndex -> 1, so it seems that the source file is corrupted. (SourceFiles at: 1) -> MultiByteFileStream: '/Users/nicolas/Smalltalk/Squeak/pharo/PharoV10.sources' Well, for my previous Pharo images, this very file works ! How damned can be the file be changed and the version not incremented ? Is it me who did something wrong ? Or the update process somewhere did condense the sources ? Or did someone elese messed with the sources ? Is it a known problem ? Any help appreciated. Nicolas
