Installing
Quartus II 13.0sp1
Ubuntu 20.04
The installer won't launch unless you install 32-bit libc:
sudo apt-get install libc6-i386
Once installed, the application won't launch without libpng12, and libpng16 is what ships with Ubuntu. Luckily there is a PPA:
sudo add-apt-repository ppa:linuxuprising/libpng12 sudo apt update sudo apt install libpng12-0
