Describe the bug
Binaries seem to drop a slash from the mountpath of disks, resulting in no tool under windows to be found:

Add any other context about the problem here.

➜  ~ cat /etc/wsl.conf
[automount]
root = /mnt
options = "metadata,umask=22,fmask=11"

[patrick330602]

can you change the "root = /mnt" to "root = /mnt/" in your /etc/wsl.conf for now to temporarily solve the issue? The fix for this issue will be included in the 3.2.0 backport to wslu in Ubuntu.

Also, please report bugs of wslu for Ubuntu following the pinged guide here in the future: #121

For this time, I will move the bug manually.

Although this is not a Ubuntu-specific bug, you have to follow this bug to track the progress for wslu for Ubuntu: https://bugs.launchpad.net/ubuntu/+source/wslu/+bug/1888869, keep in mind closing this bug does not mean it is closed for Ubuntu.
