How to install Ubuntu 21.10 on WSL for Windows 10 and 11

Installation

uninstall image (if needed)

# wsl --unregister <distroName>
wsl --unregister ubuntu-22.04

download images

From cloud images ubuntu (cloud-images > jammy > current), now there are wsl images:

I just have to download the last jammy (22.04) image jammy-server-cloudimg-amd64-wsl.rootfs.tar.gz

install and setup from powershell

I have downloaded this ubuntu image to D:\wsl\ubuntu-22.04\download

(base) guillaume@LL11LPC0PQARQ:/mnt/d/wsl$ tree
.
├── Ubuntu-20.04
│   └── ext4.vhdx
├── Ubuntu-22.04
│   ├── download
│   │   └── jammy-server-cloudimg-amd64-wsl.rootfs.tar.gz
│   └── instance

and my ubuntu-22.04 instance will stand in D:\wsl\ubuntu-22.04\instance

Install with this command from powershell

# wsl --import <distroname> <location of instance> <location of download>
wsl --import ubuntu-22.04 D:\wsl\ubuntu-22.04\instance D:\wsl\ubuntu-22.04\download\jammy-server-cloudimg-amd64-wsl.rootfs.tar.gz

It takes 3-4 minutes to install. and should be visible in your wsl instances.

 wsl --list --all -v
  NAME            STATE           VERSION
  ubuntu-22.04    Stopped         2

then to run it

# wsl -d <distroname>
wsl -d ubuntu-22.04

or

use Windows Terminal as a launcher

Windows Terminal is a smart way to group all terminals (powershell, and all your wsl instances)

It can be installed even with limited windows store access by clicking install in Installer le Terminal Windows et commencer à le configurer

Automatically all wsl instances appear in Settings.

Automatic setup

copy these 2 scripts in /root/ (given they are in D:\wsl\ubuntu-22.04\download)

cp /mnt/d/wsl/Ubuntu-22.04/download/setup_wsl_* .

setup_wsl_root.sh download

echo

echo "2. create ssh key to copy to gitlab"

		cat .ssh/id_rsa.pub
		echo "copy this content to gitlab > preferences > SSH Keys"
		read -p "Press any key to resume ..."

echo "3. update certificates"

sudo cp /tmp/devops_environment/certs/* /usr/local/share/ca-certificates/
sudo update-ca-certificates
rm -rf /tmp/devops_environment
if [ $DISTRIB_RELEASE == "22.04" ]
then
echo 'bug SSL with ubuntu 22.04 - https://bugs.launchpad.net/ubuntu/+source/openssl/+bug/1963834/comments/7'
sudo tee -a /etc/ssl/openssl.cnf << EOF
[openssl_init]
ssl_conf = ssl_sect

[ssl_sect]
system_default = system_default_sect

fi
echo

echo "4. update apt sources with artifactory"
echo 'Acquire { http::User-Agent "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:13.37) Gecko/20100101 Firefox/31.33.7"; };' | sudo tee /etc/apt/apt.conf.d/90globalprotectconf

sudo sed -i 's,http://security.ubuntu.com/ubuntu,https://artifactory.michelin.com/artifactory/ubuntu-archive-remote,g' /etc/apt/sources.list
sudo apt update
sudo apt upgrade -y
echo

Then

chmod +x setup_wsl_root.sh
./setup_wsl_root.sh

As explained stop wsl instance by running wsl --shutdown ubuntu-22.04 from powershell and start from Windows Terminal

It restarts from your user and it will install:

• setup wsl-vpnkit
• create ssh key to copy to gitlab
• update certificates
• update apt sources with artifactory

And now we can install other parts

all the scripts are in https://github.com/castorfou/guillaume_blog/tree/master/files

00 - keep config files in git

wget --no-check-certificate --content-disposition -O - https://raw.githubusercontent.com/castorfou/guillaume_blog/master/files/setup_wsl_00_config_files_in_git.sh | bash
source .bashrc

01 - automount secured vbox

wget --no-check-certificate --content-disposition -O - https://raw.githubusercontent.com/castorfou/guillaume_blog/master/files/setup_wsl_01_automount_secured_vbox.sh | bash

02 - python with conda and configure base environment (jupyterlab, mamba)

wget --no-check-certificate --content-disposition -O - https://raw.githubusercontent.com/castorfou/guillaume_blog/master/files/setup_wsl_02_install_python_conda_part1.sh | bash
cd 
source .bashrc
wget --no-check-certificate --content-disposition -O - https://raw.githubusercontent.com/castorfou/guillaume_blog/master/files/setup_wsl_02_install_python_conda_part2.sh | bash

03 - bat cat

wget --no-check-certificate --content-disposition -O - https://raw.githubusercontent.com/castorfou/guillaume_blog/master/files/setup_wsl_03_install_batcat.sh | bash
source .bashrc

04 - git access

ln -s /mnt/d/git/ ~/

05 - X access with GWSL

GWSL Homepage

if you have access to Windows Store, it is available.

Or alternate download are possible.

06 - git credential manager

wget --no-check-certificate --content-disposition -O - https://raw.githubusercontent.com/castorfou/guillaume_blog/master/files/setup_wsl_06_git_credential_manager.sh | bash

07 - install wslu

wslu

wget --no-check-certificate --content-disposition -O - https://raw.githubusercontent.com/castorfou/guillaume_blog/master/files/setup_wsl_07_wslu.sh | bash

Some examples:

$ wslfetch

$ wslpath -u "C:\Program Files\Typora\Typora.exe"
/mnt/c/Program Files/Typora/Typora.exe

08 - configure pip

wget --no-check-certificate --content-disposition -O - https://raw.githubusercontent.com/castorfou/guillaume_blog/master/files/setup_wsl_08_pip.sh | bash

09 - install vscode

code .

(given Visual Studio Code is installed on the Windows side (not in WSL))

(and if needed install Remote development)

Manual setup (skip if to follow automatic setup)

basic setup

With this way to install, you don’t have any user, you don’t have any launcher within Windows.

Create a user and add it to sudo:

# adduser <yourusername>
# usermod -aG sudo <yourusername>
adduser guillaume
usermod -aG sudo guillaume

and I can switch to this user simply with

# su <yourusername>
su guillaume

launch distro with yourusername - update wsl.conf

Manually you can now start your distro with your username from powershell

# wsl -d <distroname> -u <yourusername>
wsl -d ubuntu-22.04 -u guillaume

Or from another wsl (huge avantage to run in linux terminal instead of powershell)

wsl.exe -d ubuntu-22.04 -u guillaume

but you can better keep this username setting by updating wsl.conf

# /etc/wsl.conf
# Set the user when launching a distribution with WSL.
[user]
default=YourUserName

It is now setup. You can now shutdown this instance from powershell.

# wsl --shutdown <distroname>
wsl --shutdown ubuntu-22.04

and when starting wsl -d ubuntu-22.04, you reach your username.

wsl-vpnkit

As wsl-vpnkit is already installed, I just have to

echo 'wsl.exe -d wsl-vpnkit service wsl-vpnkit start' >> ~/.profile
source .bashrc

gitlab

ssh-keygen -t rsa -b 4096 -C "WSL2 ubuntu 22.04"

and copy id_rsa.pub into gitlab > preferences > SSH Keys

corporate CA certificates

git clone git@gitlab.michelin.com:devops-foundation/devops_environment.git /tmp/devops_environment
sudo cp /tmp/devops_environment/certs/* /usr/local/share/ca-certificates/
sudo update-ca-certificates
rm -rf /tmp/devops_environment

apt sources

had to replace focal (20.04) to jammy (22.04)

echo 'Acquire { http::User-Agent "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:13.37) Gecko/20100101 Firefox/31.33.7"; };' | sudo tee /etc/apt/apt.conf.d/90globalprotectconf
sudo sed -i 's@^\(deb \)http://archive.ubuntu.com/ubuntu/\( jammy\(-updates\)\?.*\)$@\1https://artifactory.michelin.com/artifactory/ubuntu-archive-remote\2\n# &@' /etc/apt/sources.list
sudo sed -i 's@^\(deb \)http://security.ubuntu.com/ubuntu/\( jammy\(-updates\)\?.*\)$@\1https://artifactory.michelin.com/artifactory/ubuntu-security-remote\2\n# &@' /etc/apt/sources.list

check everything is ok

• This command must return google ip:

  host google.fr

• This command must return artifactory ip:

  host artifactory.michelin.com

• You are able to update your distribution without error:

  sudo apt update
  sudo apt upgrade -y

Setup config dotfiles with whole filesystem (/)

as detailed in keep dotfiles in git

but to manage the whole filesystem.

init local repo

sudo mkdir -p /.cfg
sudo chown $USER:users /.cfg
git init --bare /.cfg
alias config='/usr/bin/git --git-dir=/.cfg/ --work-tree=/'
config config --local status.showUntrackedFiles no
echo "alias config='/usr/bin/git --git-dir=/.cfg/ --work-tree=/'" >> $HOME/.bash_aliases
cd
source .bashrc

git default identity (if needed)

config config --global user.email "guillaume.ramelet@michelin.com"
config config --global user.name "guillaume"

setup branch and push to central repo

config remote add origin git@gitlab.michelin.com:janus/dotfiles.git
config fetch
cd
config add .bashrc
config commit -m 'init with .bashrc'

config branch GR_WSL2_ubuntu22.04
config checkout GR_WSL2_ubuntu22.04
config push --set-upstream origin GR_WSL2_ubuntu22.04
