Ik have tried 2 days ago to upgrade my raspberry for upgrading also domoticz.
I run a wd pidrive with berryboot for years without problem.
Steps I did,
1 clone the installation with berryboot.
2 stop service domoticz
3 the upgrading steps 2 buster
When I did the apt get upgrade the system give a error and I tried it again nothing helped
So finally I reboot the pi, and it didn't boot.
The clone coping back for starting, but same errors
So I think let's make a new install with berryboot (afterwards also tried directly at a sd) install buster lite and install domoticz with the command as described.
It's starts so I wanted to restore my backup version 4.975 but the domoticz version is now 2020.1
A all my stuffs seems there but wait my hardware is not fine I cannot select the right usb ports.
(Also a problem with my lua script after upgrading it needs 5.3 and I used 5.2 at the old installation but first the other bigger problem)
