1 year ago Turns out I had more than one WSL distribution installed as shown below and the fact that rootfs is no longer available in WSL2 is causing issues. (see issue https://github.com/microsoft/WSL/issues/6221)
To fix script not detecting the correct WSL distro
To fix this I updated the script to first find the registry path for the current distro and then query the BasePath for the distro GUID using the newly found registry path 😄
Update line 1-5 as follows:
#!/bin/bash
# Get the Windows registry path for the current WSL distro
wsl_distro_regpath=$(reg.exe query "HKCU\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Lxss" /s /f DistributionName 2>&1 | sed -e 's|\r||g' | grep -B1 -e "$WSL_DISTRO_NAME$" | head -n1)
# Get path for WSL storage
wslroot=$(wslpath $(reg.exe query $wsl_distro_regpath /s /v BasePath | awk 'BEGIN { FS = "[ \t]+" } ; /BasePath/{print $4}' | tr -d "[:cntrl:]"))To fix WSL2 issue where rootfs is not a vailid path
Comment out the if-clause for the floopy-disk check so it becomes:
# Packer tries to create floppy in the linux /tmp folder which is not representable in Windows. Replace it with direct storage path
#if [[ $argument == /tmp/* ]]; then
#argument="$wslroot/rootfs$argument"
#fiIssue showing multiple WSL distros:

Hello, I'm using this and seeing floppy disk is failing to attach with WSL2.
