Lotus Version

v1.21.0-rc1

Repro Steps

Try to build the docker image of lotus.

docker build --build-arg LOTUS_TEST_IMAGE=filecoin/lotus-all-in-one:v1.21.0-rc1-debug --build-arg FFI_BUILD_FROM_SOURCE=0  -f Dockerfile --target lotus-all-in-one \
	-t filecoin/lotus-all-in-one:v1.21.0-rc1-debug --build-arg GOFLAGS=-tags=debug .

Describe the Bug

When I try to build a lotus docker image, it fails with below error:

Step 12/79 : RUN make clean deps
 ---> Running in df52d903b86e
Makefile:14: Your Golang version is go1.18.8
Makefile:15: *** Update Golang to version to at least 1.19.7.  Stop.
The command '/bin/sh -c make clean deps' returned a non-zero code: 2
make: *** [Makefile:232: docker/lotus-all-in-one] Error 2

I think requirement is coming from one of the dependencies and as long as user builds Lotus manually outside docker, it will work if they are using go v1.19.x
But, docker is strict in the sense it will use defined image of v1.18.x in the Dockerfile.

@rjan90 Hey, I am not able to build Lotus with go 1.18 even outside the container. I think we should update the go.mod file to 1.19 for v.1.21-0-rc1

root@c9ea3db2f2aa:/lotus# make clean all
Makefile:14: Your Golang version is go1.18.8
Makefile:15: *** Update Golang to version to at least 1.19.7.  Stop.
root@c9ea3db2f2aa:/lotus# go version
go version go1.18.8 linux/amd64

Hey @LexLuthr I updated go.mod here, so now it should be updated for the v1.21.0-rc2: https://github.com/filecoin-project/lotus/pull/10594/files#diff-33ef32bf6c23acb95f5902d7097b7a1d5128ca061167ec0716715b0b9eeaa5f6
