pak doesn't work with latest versions of littler in docker images

Strugglebussing while trying to upgrade rocker versions (from r-ver:4.2.3 to 4.4.1) and I think I've narrowed it down to either a pak or a littler issue:

FROM rocker/r-ver:4.4.1

RUN install2.r -e -r https://r-lib.github.io/p/pak/stable/source/linux-gnu/x86_64 pak

# littler's "r" doesn't work but somehow normal R does work ... ?
RUN r -e "pak::pkg_install('dplyr')"

returns this error on build:

This error seems to stem from https://github.com/r-lib/pak/blob/64a34ee61afa3885057fbf5dde41863549a6b3e3/src/library/pkgcache/R/bioc.R#L295 where it fails to call download.file?
