Installing Go 1.2 on Ubuntu 13.10
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.
The easiest way to install Go 1.2 on your system is by using the
godeb tool. Here's how.
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.
The basics of the godeb project are described on the author's blog. If you need a binary package for
godeb, check there.
Assuming that you have already installed
apt-get, it's just as easy to install
godeb as a go package:
$ cd $GOPATH $ go get launchpad.net/godeb
You should probably test that
godeb works before proceeding:
$ $GOPATH/bin/godeb --help
Since the Ubuntu
golang package will conflict, and since we've already build out
godeb tool, we can now uninstall
$ sudo apt-get remove golang
This will remove Go from your system, but will leave your
Building a New Go Debian Package
Now we can use
godeb to create a new package:
$ $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:
processing https://go.googlecode.com/files/go1.2.linux-amd64.tar.gz package go_1.2-godeb1_amd64.deb ready Selecting previously unselected package go. dpkg: regarding go_1.2-godeb1_amd64.deb containing go: go conflicts with golang golang (version 2:1.1.2-2ubuntu1) is present and installed. dpkg: error processing go_1.2-godeb1_amd64.deb (--install): conflicting packages - not installing go Errors were encountered while processing: go_1.2-godeb1_amd64.deb error: while installing go package: exit status 1
This error indicates that the
dpkg program won't install our newly created Go package because it conflicts with the
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.
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
force-overwrite flag tells
dpkg to cause this package to overwrite any files installed by the Ubuntu
Once you've run the above command you should be able to run
go version to verify that the correct Go version was installed.
Update 2014-04-08: Daniel Hunsaker explained the real solution to
dpkg failure, and provided a a better solution:
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!
Update 2014-03-04: Thanks to Jeff Graham for suggesting a fix to a typo.
