[systemd-devel] nspawn: No Return key in machinectl login?

[Tobias Hunger]

Hello,

I am having a problem with one of my containers set up with
systemd-nspawn. For some reason the return key will not work most of
the time (19 out of 20 attemps) after doing machinectl login into that
machine.

This effects not all programs: bash works, fish-shell does not. Sudo
password entry does not work either. Git is broken (but hardly ever
requires user input, so that is not that tragic;-), vi works fine.

I only have this one one container image, even though it is built
based on an image that is also used by container images that work
fine. So I think the image should have all the important bits and
pieces in place.

I am kind of lost that close to the termcap:-) Does somebody have any
ideas on how I can debug this?

I did try editing the agetty set-up by container-getty at .service to use
different terminfos (in fact the infocmp is with "linux" instead of
the default "$TERM"), but no change.

Best Regards,
Tobias
