Hi, I have installed Pharo on Ubuntu 15.10 (64 bits) with help of another user who ask me to report the troubles we have encountered.
By following the instruction on the page http://pharo.org/gnu-linux-installation (and make "sudo apt-get install pharo-vm-core" then "sudo apt-get install pharo-launcher"), the file vm-display-X11 was missing. Then we have try "sudo apt-get install pharo-desktop pharo-launcher", we got the VM but without "PharoV40.sources", it was from 1 to 3 only. So we have donwload it from sources and fix it manually " wget -O- get.pharo.org/50+vm | bash sudo cp ~/pharo/pharo-vm/PharoV40.sources ../../share/pharo-vm/ sudo ln -s ../../share/pharo-vm/PharoV40.sources " Cordially, Marion Noirbent
