[BUG REPORT]:

[BUG | ISSUE] Actual Behaviour:

After uninstalling Pi-hole and most of its dependencies (except for curl, wget and unzip) the rsync-command cannot be executed any more -> "Command not found".

I have tested this three times, so I guess it is reproducible.

[BUG | ISSUE] Steps to reproduce:

Uninstall Pi-hole with "sudo pihole uninstall". Remove all dependencies except for curl, wget and unzip. I don't know if this also happens when you don't remove any dependencies.

The dependencies include utilities that are already installed on various distributions, they should not all be removed, or you will take out packages that existed prior to installing the Pi-hole. Uninstalling the Pi-hole software via the script isn't the best currently, but just walking through the script and uninstalling everything without checking to see what utilities and software will be removed when done manually will break your OS.

[beatschubser]

Fair enough, but then the script shouldn't say

SAFE TO REMOVE ALL ON RASPBIAN

What's the best way to uninstall Pi-hole? Love the tool, but it crashes my SmartHome-Server (FHEM).

This does not seem to be an issue on v3.2--we did give the uninstaller some love, but it appears to be fixed.
