Error: quartus_map ended unexpectedly

Google translate is your friend (Do not work anymore because of the https...).

But to solve the problem, you just need to do the echo.

The file /etc/issue contain special char to clear the screen at boot (not ascii) and Quartus can not handle it.

Why Quartus need to read this file ? I don't know and it doesn't make sens for me...

So the solution it's to remove special char into that file.

You can do hexdump /etc/issue to see these specials char.

You can save the file before if you want :

cp /etc/issue /etc/issue.back

But anyway you just need to do as root this command :

echo "Arch Linux  \r  (\n) (\l)" > /etc/issue

Any way if you didn't understand this post too, I can't help you more (I am french)
