I installed Go (golang) in Ubuntu 13.10, but the available package currently installs version 1.1.2, while I need at least 1.2 for a project. Online HOWTOs were weak, and or outdated, but I found this script online. I fixed some errors in it and then posted it here to share. As always, read the script to understand what it does before you run it…

#NOTE: last line errors with: go tool dist: unknown $GOARCH x86_64 - hard-coding for great justice!
