Ongoing notes on things I did to get WSL2 to work

mestrak profile image MeStrak Originally published at mestrak.com Updated on ・5 min read

In the interests of productivity, and many issues trying to get dev stuff to work on my Windows workstation I started to use WSL 2 (I skipped WSL 1).

This post will be used for ongoing notes of things that I had to fix during the setup. It might not be complete as I'm starting my notes after the fact but I'll do my best to remember everything.

All the fixes are actually simple, but hopefully it will still be useful to save some time for people facing the same issues.


NPM/Yarn install not working

Unfortunately I don't have a log of the exact error messages from this time, but when trying to install these package managers I got an error message (something related to not being able to connect - I couldn't even ping anything external).

The fix 🚀

DNS settings had not been configured, even pinging external sites didn't work.

  1. Create a file: /etc/wsl.conf.
  2. Put the following lines in the file in order to ensure the your DNS changes do not get blown away
    [network]
    generateResolvConf = false

  3. In a cmd window, run wsl --shutdown

  4. Restart WSL2

  5. Create a file: /etc/resolv.conf. If it exists, delete and replace existing one with this new file (sudo rm /etc/resolv.conf to delete, and if you get a warning about an existing swap file then D to delete it).

  6. Put the following line in the file
    nameserver 8.8.8.8 (or use your DNS server instead of 8.8.8.8 which is a Google DNS server)

  7. In a cmd window, run wsl --shutdown

  8. Restart WSL2

error: linker cc not found when compiling rust code

When running rustc I came across the following error, basically because gcc wasn't installed.

$ rustc fart.rs
error: linker `cc` not found
  |
  = note: No such file or directory (os error 2)

error: aborting due to previous error

The fix 🚀

$ sudo apt update
$ sudo apt install build-essential

I did actually have more errors than this which I've written up separately, see the 404 not found error below


Package installation fails with 404 errors

Annoying errors like the one below to show when I was installing some new packages (actually after trying to install build-essential).

$ sudo apt install build-essential

The important bit:

Running with --fix-missing as suggested in the error message and a few blog posts gave the same error.

sudo apt-get update didn't work either:

The fix 🚀

The issue was that my clock was out of sync with the Windows host (I don't know why).

$ sudo hwclock --hctosys

After this $ sudo apt update ran happily, as did $ sudo apt install build-essential.

Can't add python poetry auto completions for bash

Got the error bash: /etc/bash_completion.d/poetry.bash-completion: Permission denied when running the following command:

$ poetry completions bash > /etc/bash_completion.d/poetry.bash-completion

At the time of writing (10 Aug 2020), according to the output of $ poetry help completions this should be the command to install bash completions for poetry.

The fix 🚀

Run this command instead!

$ poetry completions bash | sudo tee /etc/bash_completion.d/poetry.bash-completion
