My goal is to run OpenStack Pike on Raspberry Pi 3B+.

I've chosen SLES 15 as SLES 12 doesn't seem to run on this hardware. (I tried and it didn't even boot.)

Now, I am following the installation guide at https://docs.openstack.org/install-g...aging-obs.html
I ran into issues while trying to install RabbitMQ.
This is my first time using SUSE and I'm not too familiar with fighting dependencies and managing packages either.

So, I've currently made the following assumptions and discoveries while fighting the issue:

1. RabbitMQ doesn't run out of the box when following the installation guide.
2. RabbitMQ requires Erlang
3. Erlang requires libcrypto.so.1.0.0
4. libcrypto.so.1.0.0 is provided by libopenssl1_0_0

5. Aha! SLES 15 comes with libopenssl1_1, so I have already libcrypto.so.1.1

Internet suggested the following trick:

Code:
$ ln -s /usr/lib64/libcrypto.so.1.1 /usr/lib64/libcrypto.so.1.0.0
However, this didn't work - I did the test suggested at https://github.com/lfex/dockerfiles/issues/9:

Code:
$ erl
1> crypto:start().
I'm getting the NIF message about missing libraries.

And if I understood correct, the reason was that the new version of libcrypto is missing some symbols that Erlang would need.
So, now I'm trying to install libopenssl1_0_0 to have the correct libcrypto available.

Code:
$ wget http://download.opensuse.org/repositories/security:/tls/SLE_15/x86_64/libopenssl1_0_0-1.0.2p-49.1.x86_64.rpm
$ zypper in /home/uname/Downloads/libopenssl1_0_0-1.0.2p-49.1.x86_64.rpm

Resolving package dependencies...
Nope, doesn't work as such. No idea how to fix the _tmpRPMcache_ issue?
So let's try directly with RPM:

Code:
$ rpm -ih -vv http://download.opensuse.org/repositories/security:/tls/SLE_15/x86_64/libopenssl1_0_0-1.0.2p-49.1.x86_64.rpm

I'm missing multiple different versions on libc.so.6?
How come there are multiple versions of GLIBC_X.Y that I need?

Lastly:

Code:
$ ldd --version

Where to go from here?
I've been trying to figure this out for two days now and I'm not sure if I'm even anywhere near the right track towards the solution.

It all starts from:

Code:
$ zypper install rabbitmq-server
Problem: nothing provides libcrypto.so.1.0.0()(64bit) needed by erlang-19.3.2-1.1.aarch64
