I am trying to run observerfrom iex, but I'm not sure why it is not working. A few days ago, he worked without problems. I regularly update my Ubuntu with the ability, so there may be a problem. Here is the error received from iex:

Any help?
Update:
There are strange things. I removed the Elixir packages with capabilities. Then I installed esl-erlang from the erlang solution repository (I think). Installed version - RC version !!! What for? Some dependencies have been installed with this package, for example libwxbase-3.0. In addition, I installed Elixir with no dependencies. But the observer is still not working.
There is an erlang-observer package, but it cannot be installed using esl-erlang.
Thanks in advance
