Package: ppp-deb
To recreate this issue... boot the latest Debian 12 netinst ISO and at
the boot menu hit escape then at the boot: prompt type in...
installgui modules=ppp-udeb
Then d-i will start and after choosing language etc... it'll try to find
any see PPPoE concentrators and say they're not detected.
After you can go to 'Execute a shell' and you'll find that they're
actually there and it shouldn't be a problem...
~ # ip link set ens192 up
~ # pppoe-discover -I ens192
Service-Name: datasuite12.13
Access-Concentrator: datasuite12.13

I even made a stupid animated GIF to show these steps in action...

It seems someone else 14 years ago wrote about this in bug #587850 but
nothing was resolved and he was told to talk to his ISP.
In this case I work for the ISP, so I'm pretty confident in the fact
that the PPPoE concentrator is there.
I can do more tests if you've got idea where to go from here.
