[solved] Systemd pager prints all input

I did some system maintenance yesterday I had to use `systemctl --no-pager` all the time as the pager / less cannot be interacted with. Instead all input is just printed at the bottom of the terminal. I.e. `j` or `^[OB` is printed if I try to navigate down via `j` or the arrow down key. I cannot say since when this is the case. The only thing still working is `ctrl+c`.

I have neither $SYSTEMD_PAGER nor $SYSTEMD_LESS set, and even if I set them to their default values ("less" and "FRSXMK") nothing changes.
This behavior is terminal agnostic (I have confirmed it in termite, gnome-terminal and on the tty). If I use less directly, everything works as expected.
I've verified with `ps` the the used pager really is less. The problem exist as the regular user and as root.

Does it happen as well if you switch to a different shell (e.g. bash to zsh/zsh to bash)?

Re: [solved] Systemd pager prints all input

No, it doesn't. Thanks a lot. I could locate the problem to a broken perl package in my $PATH I completely forgot I had installed..
