WARNING lchown operation not permitted [2!]

Summary

Hello world,

I just ran into something very similar to issue #1180 (closed) , but since the thread is old and closed I thought I'd open a new one instead of necroposting there. The problem is still in different stages being run by different runners, and I see the warning message when a runner downloads artifacts made by another runner. Unfortunately, when this happens, the second runner's pipeline fails: in one case, a file that is to be #included cannot be found, but it is definitely there, while in the other case I don't get a useful error message. The pipeline works when a single runner is enabled and runs it all.

Steps to reproduce

Setup a pipeline as per the YAML file below. Enable two runners for the same repository, then run a pipeline. What usually happens is that buildDependencies and build-Makefile are assigned to one of the runners, build-CMake to the other.

.gitlab-ci.yml 
stages:
    - prepare
    - build

buildDependencies:
    stage: prepare
    artifacts:
        paths:
            - fenics-hpc/install/
            - fenics-hpc/source/unicorn/
        expire_in: 1d
    script:
        - mkdir -p fenics-hpc/install
        - mkdir -p fenics-hpc/source/unicorn
          # many more commands that fill these two folders

build-Makefile:
    stage: build 
    script:
        - make -j2

build-CMake:
    stage: build
    script:
        - mkdir build
        - cd build
        - cmake ..
        - make -j2

Actual behavior

The runner running build-CMake shows the warning message when extracting artifacts from the previous stage, plus other warnings down below, and ultimately fails to complete the step.

Expected behavior

All the steps complete normally

Environment description

They are both shell runners, a linux/amd64 and a linux/armhf.

I don't have a .toml configuration file, or I am using the default.

Used GitLab Runner version

One runner is running version 11.5.1 [I don't have access to it], the other one version 11.2.
