Removing old python2 modules, crashes Weewx

[Phil Green]

Hello,

I have been running Weewx and am up to date with version 4.5.1.

When I updated several versions ago I migrated to python3 and installed all the prerequisites, and used the relevant pythin3 commands to build & install.

System been running fine.

I decided to update the reset of the Raspberry Pi command line system using:-

sudo apt-get update

sudo apt-get upgrade

I noticed that it reported several python packages serial 7& usb etc were no longer required, I presume the python 2.7 versions.

So I removed them with the option auto remove.

My Weewx program then fails to start.

Fortunately I had made a back and everything is running again.

So when I installed/upgraded using the python3 option I presume Weewx is running under python3?

Am I still running under python2.7?

If I issue the command python -version it reports version 2.7 from the command line.

Any advice welcome.

Regards

Phil

Look in the log. When you start up weewx, it will show you exactly which version of python it is using.

Hello Tom,

Yes I can confirm that it says python version 3.7.3 on startup in the log.

So why would using sudo apt-get autoremove and it removes python-serial and python-usb, not python3 versions would it stop Weewx running?
Thanks for any advice.

Regards

Phil

All looks fine to me.

I use to use the apt-get install Weewx method, is this message when I run sudo apt-get update an artefact of running that method?

You can’t explicitly accept with apt-get.  You have to use apt.

Please run:

apt update

apt full-upgrade
