  • Win10 tools and settings for work with Ubuntu

    I spent a last few years working in Ubuntu and Linux Mint. Now I have a new computer and will do the setup with Win10 and WSL2.

    WSL settings and setup

    Turn Windows features on or off:

    • Telnet client
    • Virtual Machine Platform
    • Windows subsystem for linux

    Powershell: 

    wsl --set-default-version 2

    Tools and apps

    • Ubuntu – install from windows appstore
    • Windows terminal – install from windows appstore
    • Docker desktop – needed for running docker in linux subsystem
    • Dbeaver.io – for accessing databases
    • Visual Studio Code

    Ubuntu settings

    ssh key

    windows terminal -> settings -> starting directory /mnt/d/

    Trouble with accessing D: drive as a regular user
    create or edit file /etc/wsl.conf and change default username to yours:

    [user]
    default=roman
