Hello,
The Pi 3B that uses my 2PAC's was running on Raspbian Stretch.
This device was also my Pi-hole dns server.
As I wanted to update the pi-hole I noticed that the OS was unsupported so I upgraded to Buster.
Since then the cgminer didn't start anymore.
I tried running the commands on post 1 again and everything works until I try the make command.
It always nags about a missing curl altho I installed several versions already.
Any idea on how to get a (recent) working version again?
