Breaking dependencies for rabbitmq-server on Ubuntu 18.04 due to update for erlang from 1:24.3.4-1 to 1:25.0-1

The current update is unstalling rabbitmq-server & erlang. I will not get reinstalled due to missing dependencies.

Installed is:

E: Unable to correct problems, you have held broken packages.

We are aware of this but there is nothing that can be done in this package.

RabbitMQ Debian package does not specify 25 as supported. It would be fine but on Launchpad PPA, as soon as 25.0 published, the previous 24.3 version was deleted by Launchpad itself. No other package hosting service works this way.

We won't be issuing updates for Ubuntu 18.04 for much longer since that distribution is 4 years old. But we plan on bumping the allowed version range for RabbitMQ packages.

@moerkey If my understanding is correct, you're using Cloudsmith to provision Erlang and you get the latest version, that is 25.0 currently. RabbitMQ Debian package does not support Erlang 25 as @michaelklishin pointed out. You should use version pinning to make sure to stick to e.g. Erlang 24.3.x.

Thank you for your help so far. We will use version pinning in the meantime.

But I don't really get it. Who defines the dependencies? https://www.rabbitmq.com/install-debian.html is saying that Ubuntu 18.04 is still supported.

We are using the repos from CloudSmith. The packages erlang-* and rabbitmq-server are provided by you?! So don´t you define these dependencies?

Packages themselves define the dependencies. However, the user controls what repositories will be searched for the packages, what versions may be forced via pinning, and so on.

We are not aware of any problems with Cloudsmith, only a combination of Launchpad and any other soure.

As of last night, a new round of RabbitMQ releases lists Erlang 25.0 as supported, so Erlang can be installed from Launchpad again.

I don`t get it. We are using the lists from CloudSmith. Why are you repeating with Launchpad? So the problem is that the packages on CloudSmith have wrong dependencies defined. Am I wrong?

JFYI: I retested it. The packages on CloudSmith are updated too. Problem solved. Thank you.

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

Of course you can not. The package rabbitmq-server was fixed 8h ago.

I am well aware of that as I released it.

I cannot go back in time but you may be the only person who run into an issue with Cloudsmith. There were no other reports. There were multiple from Launchpad users.

But I don't really get it. Who defines the dependencies? https://www.rabbitmq.com/install-debian.html is saying that Ubuntu 18.04 is still supported.

We are using the repos from CloudSmith. The packages erlang-* and rabbitmq-server are provided by you?! So don´t you define these dependencies?

We provide both Erlang and RabbitMQ packages, through Cloudsmith in this case. It's just we pushed Erlang 25 packages before we pushed a version of the RabbitMQ Debian package that says it supports Erlang 25. So people would pull the latest Erlang and RabbitMQ packages would end up with Erlang 25 and RabbitMQ that says it does not support it. We're sorry about this and this should be fixed now.

rabbitmq / erlang-debian-package

Breaking dependencies for rabbitmq-server on Ubuntu 18.04 due to update for erlang from 1:24.3.4-1 to 1:25.0-1 #32
