[Python-modules-team] Bug#939324: elixir: cannot be installed without Erlang from unstable

[Michal Sidor]

Source: elixir
Version: 1.9.1.dfsg-1~bpo10+1
Severity: normal

Dear Maintainer,

I tried installing elixir 1.9.1.dfsg-1~bpo10+1 from buster-backports.
Apt marked it broken and told me to upgrade erlang-base to a version
only available in unstable, even though installed version seemed to
match the requirement.

I think it may have something to do with #930497 because non-backports
elixir 1.7.4-0.1 depends on

erlang-base (>= 1:19) | erlang-base-hipe (>= 1:19),

while elixir 1.9.1.dfsg-1~bpo10+1 depends on

erlang-base:any (>= 1:20) | erlang-base-hipe:any (>= 1:20)

and it seems buster versions of erlang don't have Multi-Arch: allowed.

I'm not familiar enough with Debian packaging to try and suggest a fix.
