How do I install erlang OTP 25 on ubuntu?

I am trying to install erlang 25 (and elixir 1.13) on my ubuntu VM, but the default version installed by apt is erlang 24.
I’ve tried both :

sudo wget https://packages.erlang-solutions.com/erlang-solutions_1.0_all.deb && sudo dpkg -i erlang-solutions_1.0_all.d
sudo apt update

and

sudo wget https://packages.erlang-solutions.com/erlang-solutions_2.0_all.deb && sudo dpkg -i erlang-solutions_2.0_all.d
sudo apt update

but in both case, running apt-cache policy esl-erlang didn’t show the desired version. I have recently installed erlang 25 on a identical vm, and I don’t remember struggling at all, so I’m guessing there’s a simple way of doing it that I just forgot ?

I hope you can help me, thank you !

    From the Erlang OTP repo, you should do:

    apt-get install erlang

    If you decide to compile from source:

    git clone https://github.com/erlang/otp.git
cd otp
git checkout maint-25    # current latest stable version
./configure
make
make install

    Alternatively, you can use Kerl:

    curl -O https://raw.githubusercontent.com/kerl/kerl/master/kerl
chmod a+x kerl

    and place kerl in your PATH so that you can invoke it from the terminal (remember to source your .bashrc or similar if you update your PATH variable there, or open a new terminal to reload the PATH env), i.e.,

    export PATH=<path-to-kerl>:$PATH

    I would recommend the usage of the Erlang Version Manager, thanks to which you can compile and install any Erlang OTP version you need, regardless of what the default version is currently available for your Linux distro.

    Installation of Erlang Version Manager:

     $ git clone https://github.com/robisonsantos/evm /tmp/evm/
 $ cd /tmp/evm/
 $ /tmp/evm/install
 $ echo 'source ~/.evm/scripts/evm' >> ~/.bashrc
 $ bash

    Installation of the specific Erlang OTP version:

     $ evm install 25.1.1 -y
 $ evm default 25.1.1
