How to uninstall Erlang on Ubuntu:

sudo apt-get purge erlang*

Uninstall Erlang on Fedora:

sudo yum remove erlang*

If you installed erlang from source using the default home directory, you would need to rm -rf /usr/local/erlang/.

Additional cleanup might me required if you had manually copied libraries or executable to other folders, like */lib or */bin.
