Has anyone been able to use the firmware selector's package customization on this RC yet? It's now been three days sense the announcement and I still haven't been able to do that for Raspberry Pi 4B 64 bit. Same error: "Unsupported branch: 23.05.0-rc1."
I'm beginning to wonder if maybe this has to do with some issue on the build server. Maybe to do with the build server being moved to new hardware and upgraded to Debian 11 back in May, or maybe it's just some code or configuration file that didn't get set correctly. I don't know. I'm just speculating, I did notice the message originally labeled it as 23.05-rc1, but then changed to say 23.05.0-rc1. I don't know if that has anything to do with it.
I use this package customization feature to add the kmod-usb-net-rtl8152 package that I need to connect my Pi to my modem via a USB Ethernet adapter. I'm just staying on 22.03 until the 23.05.0-rc1 package customization starts working.
Tagging @aparcar. Not trying to rush you guys. Just giving you a heads up in case there actually is a build server problem that needs fixing. I appreciate all the work you guys do on this as volunteers, and 22.03.5 continues to work great.
