I am trying to install elixir for the first time as mentioned in here https://elixir-lang.org/install.html#unix-and-unix-like. But I am getting this error even after I removed the previous downloaded erlang-solutions package.

I had the same problem with my Debian 9.11 section.
The problem is in
/var/lib/dpkg/info/erlang-solutions.postinst you can change
set -e to
