Hi,

just been trying to install OpenFOAM 7 on WSL. I cant get past the first step

sudo sh -c "wget -O - http://dl.openfoam.org/gpg.key | apt-key add -"

and get this error:
--2020-05-12 10:43:59-- http://dl.openfoam.org/gpg.key

EDIT:

Realized the Ubuntu version in Windows Store installed 20.4 LTS instead of 18.04 LTS . With 18.04 LTS this issue does not exist!

Hello,

I think it is a bug of Windows Subsystem Linux for Ubuntu 20.04. I hope Microsoft will fix it soon. Till that time, I followed the issue reported here. It downgrades libc6. Otherwise, you may continue to use Ubuntu 18.04. I think the issue might be fixed with WSL 2.

First, I used these commands:

sudo add-apt-repository ppa:rafaeldtinoco/lp1871129
sudo apt update
sudo apt install libc6=2.31-0ubuntu8+lp1871129~1 libc6-dev=2.31-0ubuntu8+lp1871129~1 libc-dev-bin=2.31-0ubuntu8+lp1871129~1 -y --allow-downgrades
sudo apt-mark hold libc6

Then, I installed OpenFOAM v7 as guided on cfd.direct website:

sudo sh -c "wget -O - https://dl.openfoam.org/gpg.key | apt-key add -"
sudo add-apt-repository http://dl.openfoam.org/ubuntu
sudo apt-get update
sudo apt-get -y install openfoam7

I hope it works for you as well.


EDIT: as an update, this issue is fixed in Windows 10 2004.

Hi,

I had the same issue of Martin (I have to install OpenFoam 7 on Windows 10 using Ubuntu 20.04) and I have followed your method.

I get past the "sudo sh..." step but now I have some issues with the . $HOME/.bashrc step (https://openfoam.org/download/windows-10/, User Configuration, setp 2). I get this error:

-bash: /opt/openfoam7/etc/bashrc: No such file or directory

Did you have the same problem?

Regards,
Massimo

If you installed OpenFOAM on that path, you need to use source command maybe, so try that way to check if it works:

source /opt/openfoam7/etc/bashrc when you start your terminal. Or by gedit/vim you can add those lines to the bottom of your .bashrc file. Or if you used developer version of it, you need source /opt/openfoam7-dev/etc/bashrc

I have just tried both commands but I recive the same message "No such file or directory".

I am going to unistall Ubuntu 20.04 ant try with Ubuntu 18.04 and see if I can solve the problem starting with a fresh new installation of OpenFoam7.

Thank you, best,
Massimo

I could successfully install openfoam7 in my computer.
