DE0-Nano Quartus Lite 19.1.0 Linux - Programming Failed - Error (209040): Can't access JTAG chain

The problem seems to be caused by a SW issue..

Following the suggestion posted here

https://electronics.stackexchange.com/questions/239882/altera-cyclone-ii-jtag-after-as-programming

I installed libudev:i386:

$ sudo apt-get install libudev1:i386
$ sudo ln -sf /lib/x86_64-linux-gnu/libudev.so.1 /lib/x86_64-linux-gnu/libudev.so.0

Then, after pluggin the board:

$ sudo killall jtagd
$ jtagd --user-start
$ jtagconfig 
1) USB-Blaster [1-10]
  020F30DD   10CL025(Y|Z)/EP3C25/EP4CE22

The above script can be placed the bin directory of installation, for example /opt/intelFPGA_lite/20.1/quartus/bin/usbblaster.sh (yes, I switched to 20.1 version):

#!/bin/sh
/usr/bin/killall jtagd
/opt/intelFPGA_lite/20.1/quartus/bin/jtagd --user-start
​

and udev rules set as follows:

SUBSYSTEMS=="usb", ACTION=="add", ATTRS{idVendor}=="09fb", ATTRS{idProduct}=="6001", MODE="0666", GROUP="plugdev", SYMLINK+="usbblaster", RUN+="/opt/intelFPGA_lite/20.1/quartus/bin/usbblaster.sh"

Works like a charm.
