The installation script taken from https://www.rabbitmq.com/install-debian.html#apt-packagecloud fails with:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

I reproduced it on a fresh AWS t3.small instance with Ubuntu 20.04.
This came unexpected since I was able to install RabbitMQ 3.10.2 with Erlang 24.3.4 a few weeks ago.

The script taken from https://www.rabbitmq.com/install-debian.html#apt-packagecloud is the following:

#!/usr/bin/sh

sudo apt-get install curl gnupg apt-transport-https -y

## Install rabbitmq-server and its dependencies
sudo apt-get install rabbitmq-server -y --fix-missing

The expectation would be that the install script taken from https://www.rabbitmq.com/install-debian.html#apt-packagecloud runs successfully.

Same question as #4946. There were no changes to Erlang packages on Cloudsmith. There were to Launchpad after Erlang 25.0 was published: it now only provides Erlang 25 (this is how Launchpad works) and RabbitMQ Debian packages do not list 25 as supported.

We are working on a new patch release that would make Debian packages support 25.0.

You can, in the meantime:

Install from Cloudsmith
Pin Erlang version to 24.3 to avoid such surprises next year when Erlang 26 comes out

A new round of releases listed Erlang 25 as supported in Debian package metadata.

I cannot reproduce any failures or dependency conflicts using these two sets of steps:

I can confirm that everything works as expected now. Thanks so much for your support on this issue.

Hijacking existing 2-3 year old issues is not appreciated. Neither are one sentence long "problem statements". So a few "similar questions' were deleted.

Please open a new discussion with all the relevant details or seek RabbitMQ help elsewhere.
