Sometimes its required to build from source:

apt-get install -y autoconf git wget libssl-dev realpath libsqlite3-dev libmysqlclient-dev

wget https://github.com/Kitware/CMake/releases/download/v3.16.3/cmake-3.16.3.tar.gz && tar xvf cmake-3.16.3.tar.gz && \
cd cmake-3.16.3 && ./configure --parallel=16 && \
make -j16 && make install && \
cd ..

git config --global credential.helper store

# Patchelf
wget http://nixos.org/releases/patchelf/patchelf-0.10/patchelf-0.10.tar.bz2 && \
tar xf patchelf-0.10.tar.bz2 && \
cd patchelf-0.10 && \
./configure && \
make install

# Create TeaSpeak
git clone https://git.did.science/WolverinDEV/TeaSpeak-Parent.git server && cd server && \
git submodule update --init --recursive
./libraries/build.sh




# -------- Troubleshooting ----------
If go raises an error/crashes install a newer version:
$ sudo add-apt-repository ppa:gophers/archive
$ sudo apt-get update
$ sudo apt-get install golang-1.11-go
sudo update-alternatives --install /usr/bin/go go /usr/lib/go-1.11/bin/go 1
