Why can't Go find these source files?

Question

I'm trying to compile kaniko on a raspberry pi.

I don't program in golang, but I was able to compile kaniko successfully a few weeks ago on the same raspberry pi, and even wrote myself a guide of the steps to follow, but now, following the same steps, something is broken.

kaiko requires go, but a more recent version of go then found in the raspberry pi repos, so I download and install go from scratch. go requires go to compile, so I first install it (an older version) from the repos, and then remove it after it's done compiling a more recent version of itself:

Install go:

sudo apt-get install golang
wget https://dl.google.com/go/go1.17.6.src.tar.gz 
tar -xvf go1.17.6.src.tar.gz
cd go/src
./make.bash
sudo apt-get purge golang golang-go
sudo mv -v ../bin/* /usr/local/bin
echo 'export GOPATH=~/.go' >> ~/.profile
echo 'export GOROOT=/usr/local/bin' >> ~/.profile
source ~/.profile

Compile kaniko:

sudo apt-get install git
git clone https://github.com/GoogleContainerTools/kaniko.git
cd kaniko
make

What I get is this:

It seems that go can't find the kaniko source code. Why is that? What am I doing wrong?

Answer 1

Based on the comments, my suggestion is to add $HOME/go/bin to the path and use the default GOPATH.

Go mod depends on the bin directory inside the GOPATH. It installs new packages there. The go binary itself can actually reside somewhere else. If you follow these install instruction https://go.dev/doc/install, go itself will actually be in /usr/local/go but the GOPATH is still $HOME/go.

I would also recommend, not involving apt in this at all. This looks like trouble in the form of conflicts with different installations.
