Below are a list of steps I preformed to install the Keybase client application on a Chromebook using the crouton chroot environment.
Since the Chromebook I have (Samsung XE303C12) is an ARM based device I could not use the pre-compiled
binaries of the Keybase client provided. Also the client is written in Go and
requires version of Go >= 1.5.
I followed the descriptions found at the following pages
First, let's see if we can use the Go version provided by the Ubuntu precise distribution provided by crouton.
localhost:~$ sudo apt-get install golang
...
Selecting previously unselected package golang-src.
(Reading database ... 44403 files and directories currently installed.)
Unpacking golang-src (from .../golang-src_2%3a1-5_armhf.deb) ...
Selecting previously unselected package golang-go.
Unpacking golang-go (from .../golang-go_2%3a1-5_armhf.deb) ...
Selecting previously unselected package golang-doc.
Unpacking golang-doc (from .../golang-doc_2%3a1-5_all.deb) ...
Selecting previously unselected package golang.
Unpacking golang (from .../golang_2%3a1-5_all.deb) ...
Setting up golang-src (2:1-5) ...
Setting up golang-go (2:1-5) ...
Setting up golang-doc (2:1-5) ...
Setting up golang (2:1-5) ...Now, let's check the version.
localhost:~$ go version
go version go1To bad. The default Go installation will not work.
localhost:~$ sudo apt-get remove golang
localhost:~$ sudo apt-get autoremoveSo, it seems I have to build Go myself.
First checkout the Go sources.
localhost:~$ cd projects/
localhost:~/projects$ git clone https://go.googlesource.com/go go-latest
localhost:~/projects$ cd go-latest/Since Keybase says it needs Go >= 1.5 and the Go website shows 1.6.3 as the latest stable release. We will use that.
localhost:~/projects/go-latest$ git checkout go1.6.3 localhost:~/projects/go-latest$ cd src/
localhost:~/projects/go-latest/src$ ./all.bash
##### Building Go bootstrap tool.
cmd/dist
ERROR: Cannot find /home/pieter/go1.4/bin/go.
Set $GOROOT_BOOTSTRAP to a working Go tree >= Go 1.4.Wait, what?? To build Go 1.6.3 I need to have Go 1.4?
Ok, lets try that in a different directory.
Let's clone the Go repository and checkout the go1.4 version.
localhost:~/projects$ git clone go-latest go-1.4
localhost:~/projects$ cd go-1.4
localhost:~/projects/go-1.4$ git checkout go1.4
localhost:~/projects/go-1.4$ cd src/
localhost:~/projects/go-1.4/src$ ./all.bash At the end some of the tests failed since it was trying to contact some HTTP resource, however my network was down at the time (I am actually doing on a campsite with limited network connectivity). Anyway, I assume the build was succesfull since most of the core tests succeeded.
localhost:~/projects/go-1.4/src$ cd ../pkg/tool/linux_arm
localhost:~/projects/go-1.4/pkg/tool/linux_arm$ ./dist banner
---
Installed Go for linux/arm in /home/pieter/projects/go-1.4
Installed commands in /home/pieter/projects/go-1.4/bin
*** You need to add /home/pieter/projects/go-1.4/bin to your PATH. Yep, Go 1.4 succeeded.
Now, we can build the 1.6.3 version with the previously build 1.4 version.
Go back to the go-latest repo and set the GOROOT_BOOTSTRAP environment variable.
localhost:~/projects/$ cd go-latest/src
localhost:~/projects/go-latest/src$ export GOROOT_BOOTSTRAP=/home/pieter/projects/go-1.4/Now we can build the 1.6.3 version. Run the all.bash script and wait...
localhost:~/projects/go-latest/src$ ./all.bash After some time you should see
ALL TESTS PASSED

Installed Go for linux/arm in /home/pieter/projects/go-latest
Installed commands in /home/pieter/projects/go-latest/bin
*** You need to add /home/pieter/projects/go-latest/bin to your PATH.Let's test it.
localhost:~$ export PATH=/home/pieter/projects/go-latest/bin:$PATH
localhost:~$ go version
go version go1.6.3 linux/armSuccess!
Modify .bashrc with Go specific stuff so go is in our path next time we log in.
# GO specific stuff
export PATH=/home/pieter/projects/go-latest/bin:$PATHNext, to build other Go projects (like our Keybase client)
we need to define a working directory and set this as the GOPATH variable. Within this directory we also have a bin folder which will later contain the keybase executable.
localhost:~$ mkdir ~/projects/go-path
localhost:~$ cd projects/go-path/
localhost:~$ mkdir binAdd GOPATH and the bin folder to the PATH
So, update the .bashrc file.
# GO specific stuff
export PATH=/home/pieter/projects/go-latest/bin:$PATH
export GOPATH=/home/pieter/projects/go-path/
export PATH=$GOPATH/bin:$PATHNow, we can finally build the Keybase client.
Below are the build steps as taken from the Keybase site.
Since, we have Go version 1.6.3 the GO15VENDOREXPERIMENT=1 setup is actually not needed, but I will keep it here anyway.
localhost:~$ GO15VENDOREXPERIMENT=1 go get github.com/keybase/client/go/keybase
localhost:~$ GO15VENDOREXPERIMENT=1 go install -tags production github.com/keybase/client/go/keybaseThese two steps do not provide any output or progress, so at first I was a bit confused what was going on.
However, when I paused the process (<CTRL+Z>) and moved it to the backgroun (bg) I could see
a lot of activity using top command.
After this we can see the keybase executable in the bin folder in our GOPATH directory.
localhost:~$ ls -lh ~/projects/go-path/bin/
total 30M
-rwxrwxr-x 1 pieter pieter 30M Aug 2 22:03 keybaseSo, let's test it.
localhost:~$ keybase version
Client: 1.0.16Yeah, succes!
Start the keybase service and run it in the background.
localhost:~$ keybase service&Login
localhost:~$ keybase loginRun some commands
localhost:~$ keybase id pkitslaar
