Hi

Weewx installed on a RPI 4 (Debian - Bullseye), version 5.0.1, working fine, no issues.

Just tried to update to version 5.0.2 via sudo apt update && sudo apt full-upgrade and received the following error:

I've read through the WeeWX 5 help guide and, even though I'm on Bullseye, it does state that the repository should point to Buster (which it does).

Any help for noob much appreciated.

Many thanks.

Many thanks for the heads-up.

I used the WeeWX 5 guide to reinstall the key:

wget -qO - https://weewx.com/keys.html | \ sudo gpg --dearmor --output /etc/apt/trusted.gpg.d/weewx.gpg

I then initiated the upgrade which seemed to go well until the end!

Now unable to restart WeeWX and have rolled back to the previous version.

Any idea what the issue is?

the error indicates that the weewxd process does not have permission to read/write the USB-to-serial device. make sure that the user running weewxd has read/write permission to /dev/ttyUSB0 (which is probably a USB-to-serial adapter).

for example, if user 'weewx' is running weewxd, then put the weewx user into the dialout group then restart weewxd:

sudo usermod -aG dialout weewx

sudo systemctl restart weewx

see the section about reading/writing to devices in the wiki article "what you need to know about permissions":

https://github.com/weewx/weewx/wiki/Understanding-permissions#readingwriting-data-to-a-device

please let us know what works for you. there are *so* many variations when it comes to permissions, and many different ways to make things work. we're still trying to simplify the documentation to make permissions easier to understand and deal with.

I owe you a beer (or two)!

Your are correct /dev/ttyUSB0 is indeed the USB to serial adaptor to the Vantage Vue.

I followed your instructions to the letter and I now have a fully functioning v5.0.2 or WeeWX.
