Hello I am new to that forum.
I just had the same problem and it cost me about half an hour to solve it.
Maybe after setup up the esl-erlang repository i found a packet in synaptic package manager called erlang-wx. This installed the correct library but not in
/usr/local/lib/erlang/lib/wx-1.8.1/priv as requested by iex error message.
Therefore I created a softlink in that directory to point to the installed lib
from erlang-ex at /usr/lib/erlang/lib/wx-1.8.4/priv// and now observer is working.
Thank you for posting the question.

Hey! Just a heads up for everybody. On ubuntu 16.04 upgrade to esl-erlang 21.1.3 broke observer. You have to downgrade to 21.1 to fix it

True, thanks @khaskelberg et al
On ubuntu,
After esl-erlang removal go for
apt-get install esl-erlang=1:21.1

The issue was fixed. Latest esl-erlang update (1:21.1.3-2) contains fixes.
This helped me to fix my docker stack, and I use your solution in my Dockerfile with this script:
#!/bin/bash
set -eu
################################################################################
# VARS
################################################################################
erlang_lib_dir=/usr/local/lib/erlang/lib
erlang_wx=$( find ${erlang_lib_dir} -name 'wx-*' )
erlang_wx_version=${erlang_wx##*/}
erlang_wx_dir=/usr/lib/erlang/lib/"${erlang_wx_version}"
################################################################################
# EXECUTION
################################################################################
printf "\n\nERLANG WX VERSION: $erlang_wx_version\n"
if [ -d "${erlang_wx_dir}" ]; then
# https://elixirforum.com/t/observer-start-is-not-working-on-ubuntu/6018/21?u=exadra37
rm -rvf "${erlang_lib_dir}/${erlang_wx_version}"
ln -s "${erlang_wx_dir}" "${erlang_lib_dir}"
fi
Thanks
Did anyone faced this issue on CentOS 7.3? Installing wxWidgets didnāt help.
Still working fine here on redhat (7?) with wxWidgets 2.9 installed.
In Debian and Alpine I noticed that when you install the wxWidgets with the operating system tooling you get it installed in a different path and missing the folder priv if I am not in mistake, thus you may have the same issue in Centos.
You need to compare the folder where wx-version is installed, between a working Centos version and the Cewntos 7.3, and if you find any of the issues I mentioned you will need to find a way of fixing them.
My solution in the end was to compile Erlang from the git repo, and have all the necessary dependencies already installed.
I have wrote a bash script to compile Erlang from a git branchā¦ its still a work in progress, thus it will be only merged when I have finished my Elixir Docker Stack, but you can see it at this commit or just here:
#!/bin/bash
set -eu

Just sharing what worked for me in case someone else is facing the same issue in the same setup:
- OS: Ubuntu 20.04 LTS
- Elixir: 1.12.0
- Erlang/OTP 24 [erts-12.0.2]
Solution:
sudo apt install libwxgtk-webview3.0-gtk3-0v5
