Thank you so much for octoPi, it greatly facilitates the work, but there is one problem that I would like to solve. There is a raspberry pi 3 b +, octoprint 1.3.8 installed with octopi-stretch-lite-0.15.1.
The system works, I print from it, but I cannot install plugins. It gives an error.
The possibility of updating is also blocked.
I unfortunately understand badly in Unix systems, I hope for your help
