Ubuntu 20.04 can't install esl-erlang due to a GPG signing error

[tory-kk]

Hello,
Got the same issue as in #63 today while installing Ubuntu 20.04:

$ sudo apt-get update
Ign:5 http://binaries.erlang-solutions.com/debian focal InRelease
Get:6 http://binaries.erlang-solutions.com/debian focal Release [3132 B]
Hit:7 http://binaries.erlang-solutions.com/debian focal Release.gpg

GPG error: http://binaries.erlang-solutions.com/debian focal Release: The following signatures were invalid: BADSIG D208507CA14F4FCA Erlang Solutions Ltd. <[email protected]>

W: Some index files failed to download. They have been ignored, or old ones used instead.

Installation was done:

wget -O /tmp/erlang-solutions_2.0_all.deb https://packages.erlang-solutions.com/erlang-solutions_2.0_all.deb
dpkg -i /tmp/erlang-solutions_2.0_all.deb

apt-get update # <-- this step fails

We are using https://packages.erlang-solutions.com/erlang-solutions_2.0_all.deb distribution because our legacy component requires Erlang version 20.* and we cannot upgrade it to any newer version.
