I think i got it to work, but i still can't use the command
pihole
there is still this message showing up:
command not found
But i can open up the webinterface now, but i don't know the password, after the installating there wasn't showing some. Could anyone tell me where is the password safed, so i can change it?
Judging by your previous topic's title (bash: curl: command not found), it would seem that you tried to install on a somehow incomplete OS, or at least one that would be missing curl.
