У меня есть экземпляр Ubuntu-18.04 aws. Я установил в нем Erlang / OTP 21 [erts-10.1] по этой ссылке https://hostpresto.com/community/tutorials/how-to-install-erlang-on-ubuntu-16-04/, но всякий раз, когда я пытаюсь установить ejabberd на тот же экземпляр, я получаю ошибку, подобную этой
ubuntu@ip-172-11-11-11:~$ sudo apt-get install make gcc libexpat1-dev libyaml-dev automake libssl-dev erlang build-essential libncurses5-dev openssl zlib1g-dev libgd-dev libwebp-dev fop xsltproc unixodbc-dev -y

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
erlang : Depends: erlang-diameter but it is not going to be installed
Depends: erlang-eldap but it is not going to be installed
Depends: erlang-ftp but it is not going to be installed

E: Unable to correct problems, you have held broken packages.
Поэтому я решил удалить erlang с помощью этих команд:
sudo apt-get purge erlang*
sudo apt-get remove erlang
sudo apt-get remove --auto-remove erlang
sudo apt-get purge erlang
Но даже после запуска, когда я пишу erl в командной строке, я получаю
Erlang/OTP 21 [erts-10.1] [source] [64-bit] [smp:1:1] [ds:1:1:10] [async-threads:1] [hipe]

BREAK: (a)bort (c)ontinue (p)roc info (i)nfo (l)oaded

Где я ошибся и как теперь полностью удалить erlang?
EDIT
