Actual Behaviour:
For testing I installed pihole on a Pi zero and it worked great. So I installed pihole on my Linux box with more power and the installation looked good. But after the installation the machine has no DNS resolution anymore and when I try pihole I get command not found.
Now I'm not able to uninstall pihole for re-installation. I tried a new installation (after adding all needed urls to hosts file, because no DNS for this machine), but with no luck.
Is there a way to remove pihole and do a clean new install?
Update: A new installation aborted at updating the local repo(s). I added github.com in hosts and now the installation ends at install packages. The progress bar is shown for about 1 second and then the install aborts. I remember that my pi was busy for a while at this point.
I have still no pihole command available.
Update: My DNS problem is solved. I did not know DNS settings in /etc/resolv.conf. But the installation is still aborting at the same point.
It sounds like you have an issue with some packages not installing correctly. Try manually installing the packages it lists as marked for installation. There must be some error occurring during their installation.
