I am assuming that the error comes from the line:

preBuildCommands "$DUB run --compiler=$$DC unit-threaded -c gen_ut_main -- -f generated/ut_dub_main.d -d $DUB"

in the unittest configuration as suggested for using unit-threaded. The question is why does the symbol DUB not need to be defined locally or on Travis-CI, but only on GitLab?

On Travis-CI and locally Dub find where it is, why does it not do this on GitLab? It is at /usr/bin/dub in all cases.

What is the docker image that you use ?  If it is an older version maybe that the $DUB env variable is not yet supported by the dub version that's installed (it exists since 2.084.0 according to [1]).

In my .gitalab-ci.yml I use 'dlang2/ldc-ubuntu' [2] or 'dlang2/dmd-ubuntu' [3] which give always recent versions of D.

I am using ubuntu:focal. ubuntu:bionic has ldc 1.8 which is far too old. Focal has ldc 1.20.

I think the dub version is 1.19.<something>

I am having to manually symbolically link /usr/bin/gcc and /usr/bin/cc so I suspect the installation of focal is not going quite right. Especially as I have to manually set a TZ variable to avoid a lock up.

I shall have to investigate these docker images in favour of working with a bare Ubuntu.

$DUB is a variable but not an environment variable.
This is also the background why the environment variable $DC needs to be escaped here.

Kind regards

Yes because that works reasonably well on gitlab.
The only problem is that you might have to setup other things as their ubuntu image is very light. Software like zip or even git are not there by default.

A simple example of `.gitlab-ci.yml` file to support D is

---
job:
  image: dlang2/dmd-ubuntu
  before_script:
  # tools that are not in their base ubuntu image
  - apt-get update -y
  - apt-get install -y supplemental_package_x
  - apt-get install -y supplemental_package_y
  # similarly to what's done on most of the other CI services
  script:
  - bash some_script.sh
  - dub build
  - dub test
  # - etc.
