Are you trying to use image builder? Compile from source?

[PerkelSimon]

usually I use those commands and everything works.

#sudo apt update
#sudo apt install -y build-essential ccache ecj fastjar file g++ gawk \
#gettext git java-propose-classpath libelf-dev libncurses5-dev \
#libncursesw5-dev libssl-dev python python2.7-dev python3 unzip wget \
#python3-distutils python3-setuptools rsync subversion swig time \
#xsltproc zlib1g-dev sshpass dos2unix zip
