Wait 15 minutes and I’ll do the upgrade again.

I can try the RPi upgrade again and see if the file is located within the devices directory? Dave On Thursday, 22 April 2021 at 01:14:53 UTC+1 Dave McCreath wrote: Tom Hi.

That's normally where a Vantage shows up in the device directory, but not always. The most reliable way to find out where the Vantage ended up is to unplug it, plug it in again, then type 'dmesg'. This will look something like: dmesg [14818.699217] usb 2-2.1: USB disconnect, device number 4 [14818.699660] pl2303 ttyUSB0: pl2303 converter now disconnected from ttyUSB0 [14818.699710] pl2303 2-2.1:1.0: device disconnected [14820.731608] usb 2-2.1: new full-speed USB device number 10 using xhci_hcd [14820.844750] usb 2-2.1: New USB device found, idVendor=05ad, idProduct=0fba, bcdDevice= 3.00 [14820.844756] usb 2-2.1: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [14820.844759] usb 2-2.1: Product: USB-Serial Controller [14820.844761] usb 2-2.1: Manufacturer: Prolific Technology Inc.

Now running 4.5.1 from a backup SD card and all is currently well but does not look like I'll be able to update/upgrade the RPi until I figure out what's wrong.

On rebooting WeeWx failed to start, this was post an upgrade from 4.2 to 4.5.1. (I have WeeWx added to the sources list) So, being savvy, rebooted from a backup sd card to bring the system back to where it was prior to the update/upgrade and WeeWx version 4.2. I then went about updating/upgrading WeeWx from 4.2 to 4.5 (sudo apt-get install weewx), that went fine, rebooted and WeeWx ran without any issues post the upgrade. Next I then tried sudu apt-get update && sudo apt-get upgrade again.
