I updated the Dockerfile for ubuntu replacing the PATH assignment in the 
following way:

# TeXLive binaries location
ARG texlive_bin="/opt/texlive/texdir/bin"
RUN TEXLIVE_ARCH="$(uname -p)-$(uname -s | tr '[:upper:]' '[:lower:]')" && \
    mkdir -p ${texlive_bin} && \
    ln -sf "${texlive_bin}/${TEXLIVE_ARCH}" "${texlive_bin}/default"

# Modify PATH environment variable, prepending TexLive bin directory
ENV PATH="${texlive_bin}/default:${PATH}"

Build args are not useful, because they cannot be changed based on the 
architecture, therefore I used a symbolic link to place the right directory 
within PATH.

However, I noticed that the directory /usr/share/lua/5.4 is not created 
when building the pandoc/core:edge images (that use Lua 5.4), so the module 
re.lua is not copied to the host. Is something related to changes 
introduced by Lua 5.4 ?

Moreover, while edge images build works, building from 2.19.2 fails.

Can issue a PR for updating the Dockerfile (at least for Ubuntu) to include 
the TeXLive path change ?

Cheers,

Claudio
