failed to execute :wsl dos2unix create-this-bsp..............................

[dsun01]

Dear Expert and Support, 

I was very glad to find the link that mentioned the problem and claimed solved.

failed to execute :wsl dos2unix create-this-bsp; ./create-this-bsp --cpu-name nio2_gen2_0 --no -make - Intel Communities

But, I feel very pissed that I totally don't understand what this is talking about. 

Consider that some newbies like me, could anyone be kind enough to use some plain language and write a step-by-step instruction. 

the Quartus and Nios eclipse environment are in Win10, is there unix/Ubuntu 18.04 in the win10 quartus installation? it is so confusing.

I encountered this problem while I was following the instruction of an814. 

Thank you, appreciate your help.

Hi,

For 19.1 onwards, NIOS II do not use cygwin, but uses WSL.

Hi,

I'm using Quartus version 20.1.1.

for me the solution is to set wsl version to 1.

wsl --set-default-version 2

then if Ubuntu is already installed you need to convert it to 1:

wsl --set-version Ubuntu 1

Installer WSL 2 | Microsoft Docs

Thanks

Hi, try to remove ubuntu and begin again from the beginning. try to use 1st version as by default Windows downloads the latest one, but Intel didn't launch a new version that is compatible with Ubuntu >1.
