Installing Go 1.2 on Ubuntu 13.10
+
Lakukan
  
−
Newer Ubuntu distributions ship with various versions of the Go language. Ubuntu 13.10, for instance, has an available golang-1.1.2 package. But the most recent version of Go is 1.2.
+
$ sudo apt-get install golang-go
−
 
+
$ sudo apt-get install bzr
−
The easiest way to install Go 1.2 on your system is by using the godeb tool. Here's how.
+
$ cd $GOPATH
−
 
+
$ sudo go get launchpad.net/godeb
−
==Overview==
 
−
 
 
−
godeb is a small tool that grabs the latest version(s) of Go and dynamically constructs a debian package that can be installed on your local Ubuntu/Debian machine.
 
−
 
 
−
There is one caveat to godeb, though: Recent versions of Ubuntu already have the golang package, and the packages that godeb creates will conflict with Ubuntu's package. Here we do a little work to fix that.
 
−
 
 
−
==Installing godeb==
 
  
−
The basics of the godeb project are described on the author's blog. If you need a binary package for godeb, check there.
+
Cek
  
−
Assuming that you have already installed golang via apt-get, it's just as easy to install godeb as a go package:
+
$ $GOPATH/bin/godeb --help
  
−
$ sudo apt-get install bzr
+
atau
−
$ cd $GOPATH
 
−
$ sudo go get launchpad.net/godeb
 
  
−
You should probably test that godeb works before proceeding:
+
/usr/lib/go/bin/godeb --help
  
−
$ $GOPATH/bin/godeb --help
 
  
−
Uninstalling golang
+
==Uninstall golang==
  
−
Since the Ubuntu golang package will conflict, and since we've already build out godeb tool, we can now uninstall golang:
+
Sekarang uninstall golang untuk menggunakan go yang terbaru melalui godeb
  
−
  $ sudo apt-get remove golang
+
  $ sudo apt-get remove golang-go
 +
$ sudo rm -Rf /usr/share/go/src/pkg
 +
$ sudo rm -Rf /usr/share/go/src/pkg
 +
$ sudo rm -Rf /usr/share/go/src/
 +
$ sudo rm -Rf /usr/share/go/
 +
$ sudo rm -Rf /usr/share/go
 
  $ sudo apt-get autoremove
 
  $ sudo apt-get autoremove
  
−
This will remove Go from your system, but will leave your $GOPATH alone.
+
==Buat Go Debian Package==
−
Building a New Go Debian Package
 
  
−
Now we can use godeb to create a new package:
+
Lakukan
  
 +
$ sudo su
 
  $ $GOPATH/bin/godeb install
 
  $ $GOPATH/bin/godeb install
  
−
This will attempt to fetch the latest Go distribution from golang.org and then build a debian package. If all goes will, it will use dpkg to install it for you.

OH NO! IT BROKE!

On my systems, part way through godeb's installation I received an error that looks like this:

This error indicates that the dpkg program won't install our newly created Go package because it conflicts with the golang package.

Looking at your filesystem, you should see a package file like go_1.2-godeb1_amd64.deb. If you made it that far then you are actually in good shape. We can easily resolve the error above.
+
$ sudo dpkg -i --force-overwrite go_1.2-godeb1_amd64.deb

All we need to do now is tell dpkg that we want it to install even though there could be a conflict:

−
$ sudo dpkg -i --force-overwrite go_1.2-godeb1_amd64.deb

The force-overwrite flag tells dpkg to cause this package to overwrite any files installed by the Ubuntu golang package.

    The conflict is because golang is a virtual package. You need to run apt-get autoremove after you uninstall it so that the actual packages get removed as well. Then, no manual dpkg required!
