Installing lintr for GitHub actions - r

Question

I want to adapt the boilerplate code in the r-lib/actions repo to add a linting check to my (fake) package. I have my workflow yaml as follows:
on:
push:
branches:
- main
- master
pull_request:
branches:
- main
- master
name: lint
jobs:
lint:
runs-on: ubuntu-latest
defaults:
run:
working-directory: ./mystarwars
steps:
- uses: actions/checkout#v2
- uses: r-lib/actions/setup-r#v1
- name: Query dependencies
run: |
install.packages('remotes')
saveRDS(remotes::dev_package_deps(dependencies = TRUE), "../.github/depends.Rds", version = 2)
writeLines(sprintf("R-%i.%i", getRversion()$major, getRversion()$minor), "../.github/R-version")
shell: Rscript {0}
- name: Restore R package cache
uses: actions/cache#v2
with:
path: ${{ env.R_LIBS_USER }}
key: ${{ runner.os }}-${{ hashFiles('../.github/R-version') }}-1-${{ hashFiles('../.github/depends.Rds') }}
restore-keys: ${{ runner.os }}-${{ hashFiles('../.github/R-version') }}-1-
- name: Install dependencies
run: |
install.packages(c("remotes"))
remotes::install_deps(dependencies = TRUE)
install.packages(c("lintr"))
shell: Rscript {0}
- name: Install package
run: R CMD INSTALL .
- name: Lint
run: lintr::lint_package()
shell: Rscript {0}
However, I get errors when trying to install lintr in the "Install dependencies". This step fails (silently), so then when it reaches the "Lint" step it fails with Error: Error in loadNamespace(x) : there is no package called ‘lintr’.
This remains the case whether I use install.packages(c("lintr")) or remotes::install_cran("lintr").
HERE is the full log of the "Install dependencies" step on GitHub Actions.
