[rabbitmq-discuss] Having trouble installing on Ubuntu

[Jason Carver]

> strace'ing sounds like an excellent plan.


I should preface this by saying that I am not well versed in rabbitmq or
system administration, so I may be doing something dumb here... I attempted
an strace like so:

First, a: `ps aux | grep rabbitmq` to find the phantom rabbitmq process that
apt-get install seems to have left running, followed by a `sudo kill ####`
to get rid of it

Then a `sudo strace rabbitmq-server` to start the trace.


Here are the results from strace:

> You should provide the erlang dependencies here.
If I'm reading aptitude correctly, it says that it will pull in "erlang-base
1:13.b.1-dfsg-2ubuntu1" as a dependency.

Is that enough information?

Cheers,
Carver
