install of WSL2 and convert existing images

Open a PowerShell window as an Administrator

Run wsl --set-default-version 2

update KB

--set-default-version 2 is not a valid option. KB4566116 should be installed

This can be downloaded from Catalog Microsoft Update

update kernel version

If you see this message after running the command: WSL 2 requires an update to its kernel component. For information please visit https://aka.ms/wsl2kernel. You still need to install the MSI Linux kernel update package.

Download from https://docs.microsoft.com/en-us/windows/wsl/install-win10#step-4---download-the-linux-kernel-update-package

set default WSL to be version 2

PS C:\WINDOWS\system32> wsl --set-default-version 2

convert existing images

PS C:\WINDOWS\system32> wsl --list --verbose
  NAME            STATE           VERSION
* Ubuntu-18.04    Running         1
PS C:\WINDOWS\system32> wsl --set-version Ubuntu-18.04 2
La conversion est en cours. Cette opération peut prendre quelques minutes...

It took a while (~1 hour) for my unique ubuntu image.

And at the end it has worked.

PS C:\WINDOWS\system32> wsl --list --verbose

CUDA error at ../../common/inc/helper_cuda.h:777 code=35(cudaErrorInsufficientDriver) "cudaGetDeviceCount(&device_count)"

There is an error when launching CUDA samples. Googling that error maybe my video card is running on low driver version?

I have posted on nvidia (cuda+wsl) forum: https://forums.developer.nvidia.com/t/cuda-sample-throwing-error/142537/18

(update 09-22: it is not possible to have cuda on wsl2 if not in Windows Insider build from Dev Channel. (20145 or higher))

because I am in version 1909 (18363.1049), it won't work for me. ;(

cuda for WSL

Here is a link that could be interesting: https://docs.nvidia.com/cuda/wsl-user-guide/index.html

According to this, I should not have installed cuda but cuda-toolkit. Do not choose the cuda, cuda-11-0, or cuda-drivers meta-packages under WSL 2 since these packages will result in an attempt to install the Linux NVIDIA driver under WSL 2.

Is it causing my issue?

apt-get install -y cuda-toolkit-11-0

install a new distro (ubuntu 20.04)

Because I cannot use windows store, I have to manually install https://docs.microsoft.com/fr-fr/windows/wsl/install-manual

Installation by just launching Ubuntu_2004.2020.424.0_x64.appx.

I have now 2 distros,

PS C:\WINDOWS\system32> wsl --list -v
  NAME            STATE           VERSION
* Ubuntu-18.04    Running         2
  Ubuntu-20.04    Running         2

WSL2 and network

There is a change of network architecture between WSL 1 and WSL 2. In WSL 2, a new network interface is available:

Carte Ethernet vEthernet (WSL) :

   Suffixe DNS propre à la connexion. . . :
   Adresse IPv6 de liaison locale. . . . .: 
   Adresse IPv4. . . . . . . . . . . . . .: 192.168.81.193
   Masque de sous-réseau. . . . . . . . . : 255.255.255.240
   Passerelle par défaut. . . . . . . . . :

Revert image to WSL1 to get back network access

access to linux files from windows

For running state distros:

Files are available at \\wsl$\.

For stopped state distros:

Files are available at C:\Users\<users>\AppData\Local\Packages\CanonicalGroupLimited.Ubuntu*\LocalState\rootfs

some usefull wsl commands

List distros

!wsl --list --verbose

* Ubuntu-18.04    Running         1

  Ubuntu-20.04    Stopped         2

Stop a distro

!wsl --terminate Ubuntu-18.04

Update dns settings

as explained here

just switch from generateResolvConf = true to generateResolvConf = false in /etc/wsl.conf and edit /etc/resolv.conf

But still have issues, mainly I think linked to Symantec Endpoint protection.

Workaround network issue with WSL2

https://github.com/sakai135/wsl-vpnkit

installation setup

vpnkit

install docker for windows

install genisoimage in ubuntu (from http://archive.ubuntu.com/ubuntu/pool/main/c/cdrkit/genisoimage_1.1.11-3.1ubuntu1_amd64.deb)

install vpnkit

isoinfo -i /mnt/c/Program\ Files/Docker/Docker/resources/wsl/docker-for-wsl.iso -R -x /containers/services/vpnkit-tap-vsockd/lower/sbin/vpnkit-tap-vsockd > ./vpnkit-tap-vsockd
chmod +x vpnkit-tap-vsockd
sudo mv vpnkit-tap-vsockd /sbin/vpnkit-tap-vsockd
sudo chown root:root /sbin/vpnkit-tap-vsockd

npiperelay

install unzip in ubuntu (from http://archive.ubuntu.com/ubuntu/pool/main/u/unzip/unzip_6.0-25ubuntu1_amd64.deb)

download npiprelay (from https://github.com/jstarks/npiperelay/releases/download/v0.1.0/npiperelay_windows_amd64.zip )

install npiprelay

unzip npiperelay_windows_amd64.zip npiperelay.exe
rm npiperelay_windows_amd64.zip
mkdir -p /mnt/c/bin
mv npiperelay.exe /mnt/c/bin/
sudo ln -s /mnt/c/bin/npiperelay.exe /usr/local/bin/npiperelay.exe

socat

install socat in ubuntu (from http://archive.ubuntu.com/ubuntu/pool/main/s/socat/socat_1.7.3.3-2_amd64.deb)

Configure DNS for WSL

Disable WSL from generating and overwriting /etc/resolv.conf.

sudo tee /etc/wsl.conf <<EOL
[network]
generateResolvConf = false
EOL

Manually set DNS servers to use when not running this script. 1.1.1.1 is provided as an example.

sudo tee /etc/resolv.conf <<EOL
nameserver 1.1.1.1
EOL

wsl-vpnkit

from https://github.com/sakai135/wsl-vpnkit/archive/refs/heads/main.zip

unzip ~/git/wsl-vpnkit-main.zip -d ~/Applications/wsl-vpnkit

execution

~/Applications/wsl-vpnkit/wsl-vpnkit-main$ sudo ./wsl-vpnkit

proxychains

I can now use proxychains and everything works beautifully ;)

clean from local deb install to ubuntu repo

~/git$ ls *.deb
genisoimage_1.1.11-3.1ubuntu1_amd64.deb                proxychains_3.1-8.1_all.deb
libproxychains3_3.1-8.1_amd64.deb                      socat_1.7.3.3-2_amd64.deb
net-tools_1.60+git20180626.aebd88e-1ubuntu1_amd64.deb  unzip_6.0-25ubuntu1_amd64.deb

sudo apt remove genisoimage  net-tools  socat unzip
sudo proxychains apt install genisoimage libproxychains3 net-tools proxychains socat unzip

I don't exactly see how to do it with proxychains.
