Diagnostic Logs

Previously:

I was customizing zsh shell in kali. When I encountered some error messages and cant anyway get rid of those, I decided to remove the distro completely.

Using following steps:

1. Uninstalled Kali Linux from Apps
2. Open PowerShell

run: wsl -l

run: wsl --unregister kali-linux

run: wsl -l

Then:

I reinstalled the kali-linux again using wsl --install kali-linux command. And started facing this error. I have tried again to uninstall and reinstall but the issue persists.

Temporary Solution:

When I delved more into this, I found out there is an error in /etc/profile file in the shell at a certain line. I could fix the issue by adding $i in a line after a . as seen in other distros' same file.

The issue is solved temporarily, but further, down the road, it introduces more errors. For example, when I try to reset the Kali Linux app, it'd not reset back to its first state but would not run anymore. Then I would go into further error checking and go into solving the further issues.
