Build Error on 0.4.22 - go version issue

[NJITman]

According to docs, the go version needed for build 0.4.22 is go 1.12.7.

Go Version

go version go1.12.7 linux/amd64
git sha of code: 4e981576b71665f2a9ba71fbf479204802a03a37
Linux raft 5.2.8.a-1-hardened #1 SMP PREEMPT Fri Aug 9 20:17:59 CEST 2019 x86_64 GNU/Linux
built on Tue 13 Aug 2019 07:12:44 AM PDT

Installed go 1.12.7 and verified operation. Using the following steps to install and build go-ipfs.

export GO111MODULE=on
git clone https://github.com/ipfs/go-ipfs
cd go-ipfs
go get github.com/ipfs/go-ds-s3/plugin@latest
echo "s3ds github.com/ipfs/go-ds-s3/plugin 0" >> plugin/loader/preload_list
make build
go mod tidy
make build
make install

During go get step, I get about 10 errors like the following, each with different go version requirements. So, it looks like 1.12.7 is too low a version for several of the modules.

# github.com/hashicorp/go-multierror
/root/go/pkg/mod/github.com/hashicorp/[email protected]/multierror.go:115:9: undefined: errors.As
/root/go/pkg/mod/github.com/hashicorp/[email protected]/multierror.go:120:9: undefined: errors.Is
note: module requires Go 1.13

or

go build crypto/ed25519: no Go files in 
# github.com/decred/dcrd/dcrec/secp256k1/v4
/root/go/pkg/mod/github.com/decred/dcrd/dcrec/secp256k1/[email protected]/loadprecomputed.go:53:22: undefined: io.ReadAll
note: module requires Go 1.16

When I run make build, I get the following error (the failing module is one of the ones above):

build github.com/ipfs/kubo/cmd/ipfs: cannot load crypto/ed25519: cannot find module providing package crypto/ed25519
go version go1.12.7 linux/amd64
bin/check_go_version 1.17
fatal: go version '1.12.7' should be at least '1.17'
=> Please take a look at https://golang.org/doc/install to install or upgrade go.
make: *** [mk/golang.mk:80: check_go_version] Error 1

I tried a completely new install using go 1.18.4 and although that removed all of the go get errors for version mismatch, it failed during make build with Error 2. I would have to setup that install again to provide additional error details.

This is all being done on a EC2 instance running Ubuntu 20.04.

Ended up using plugin version 0.12.1 with go version 1.17 and everything worked fine. Not sure why the plugin version 0.42.22 is referencing go version 1.12.7, but that combo definitely does not work.

That's saying: if you want to use this plugin with the 0.4.22 go-ipfs build uploaded at dist.ipfs.io, you need to build with go 1.12.7. However:

1. That's just an example. You shouldn't be using go-ipfs 0.4.22 at this point, the latest version is 0.14.0.
2. If you wanted to build against go-ipfs 0.4.22, you'd need to use https://github.com/ipfs/go-ds-s3/tree/release/v0.4.22 (not master).
