 The correct way on Debian is to remove above lines.
 You may also append $PATH during the assignment like below, but this lead to some [other problems](https://salsa.debian.org/debian/WSL/-/commit/7611edba482fd0b3f67143aa0fc1e2cc1d4100a6) with WSL and VSCode..
 
+```Bash
+if [ "`id -u`" -eq 0 ]; then
+  PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:$PATH"
+else
+  PATH="/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:$PATH"
+fi
+```
