I have recently installed Quartus standard edition 20.1 on Ubuntu 18.04.5 LTS.
After adding the path to cyclone v file to install the device, following error dialog box appeared .
First the error_window appeared and after clicking the okay button. the next error window opened.
After that it promoted for a reboot, but after reboot it asked for the license file again and then showed no device installed.
Kindly look into it.
Could you install following libraries?
Install libc6:i386, libncurses5:i386, libxtst6:i386, libxft2:i386, libstdc+
+6:i386, libc6-dev-i386, lib32z1, lib32ncurses5, lib32bz2-1.0, and libpng12
Note: • For Ubuntu 18.04, additionally install libqt5xml5 and liblzma-dev libraries.
Once done, reinstall Quartus Prime. You may need to refer to document below related to
Intel® FPGA Software Installation and Licensing. Please follow all the procedures that should be good already.
Then make sure the device .qdz file is in same directory with Quartus installer. Install the device support.
