Thanks for this.

I can't immediately see the package that might be causing the conflict here.

AFAIK this should still work, but apt might need a bit of help to find the
solution you want: it uses the first/default option which can lead it down the
systemd route.

My suggestions:

 - Ensure you have the correct apt sources and remove any pinning or held

 - apt update

 - Manually install the new elogind, libelogind and libpam-elogind.

 - apt upgrade

 - apt dist-upgrade

If you find apt is trying to install systemd at any of these steps, we need to
identify the package that has a hard systemd dependency and deal with it.

HTH. Let me know how you get on.
