I tried to set up a Raspberry Pi 3b+ with OctoPi (0.18.0 with OctoPrint 1.7.2). Installation and test prints worked fine, but when I'm trying to install the Software for On-Off Shim, i get the message "Apt failed to update indexes!". With Rasperry Pi OS the shim works fine.
Is there any way to get this working?
The Shim i use: OnOff SHIM (micro-USB) – Pimoroni
