Description
The Intel® Quartus® Prime software version 18.1 requires additional libraries to be installed for Ubuntu 18.04 LTS.
Resolution
To work around this problem, make sure the following libraries are installed for Ubuntu 18.04 LTS:
libc6:i386, libncurses5:i386, libxtst6:i386, libxft2:i386, libc6:i386, libncurses5:i386, libstdc 6:i386, libc6-dev-i386, libxft2, lib32z1, lib32ncurses5, lib32bz2-1.0, libpng12, libqt5xml5, liblzma-dev
Since libpng12 is no longer available via the apt-get method, download and install libpng12 from this location https://packages.ubuntu.com/xenial/amd64/libpng12-0/download
This information is scheduled to be updated in the Intel® FPGA Software Installation and Licensing document in a future release.
