I wanted to upgrade to Go 1.3 on my Desktop at work. The version of Go shipped with Ubuntu 14.10 is 1.2. I found this article talking about godeb a go program to package Go into a .deb file installable on Ubuntu.

You still need Go 1.0+ installed, otherwise the installation is straightforward:

$ go get

And it’s easy to use:

$ $GOPATH/bin/godeb list

$ sudo $GOPATH/bin/godeb install 1.3.3

You may to rebuild you Go packages after the install, the easiest is to delete the old version and let Go rebuild them when they are needed:

$ rm -rf $GOPATH/pkg/*
