Cumulus Support

Code: Select all

sudo apt purge mono-complete
sudo apt install mono-complete

I actually fixed things by running

Code: Select all

sudo apt remove mono-complete
sudo apt autoremove
sudo apt install mono-complete 

but I expect the best option is to use purge.
A restart is required and then things seem to be working.
Thanks for everyone's help!

Excellent. @dazza1223 what if you added some kind of a readme file to the boot partition or user home directory containing the info required to get it running on Pi1 and Pi zero?

From my understanding purge does the same thing as remove/autoremove. Just saves one command line.

No - that's wrong

Apt remove - removes the app and other crap you installed with it (sometimes the whole desktop environment if you are not careful)

However if you then go back and install it again, your configs from the previous install are still there, so if you had an issue with something it might not be fixed

apt purge - purges the user configs etc as well, basically resetting it to a default install. (not including files created in user home folders)

Sorry - I'm not always a pedant, but I felt this needed corrected hehe.

autoremove - can then go back over something with orphaned dependencies that were not needed when the app was removed.

CMX is running in RaspBerryPi 1 and it works fine, however I am finding the following messages (just realized now)

2023-07-15 22:08:14.784 Failed to get the latest build version from GitHub
2023-07-15 22:08:14.845 Failed to get the latest build version from GitHub - Exception Type: System.Threading.Tasks.TaskCancele
dException
Message: The operation was canceled.
Inner Exception...
Exception Type: System.Security.Authentication.AuthenticationException
Message: Authentication failed, see inner exception.

How could I know the reason of the problem?

Thanks

Is this your own image with CMX installed manually, or the downloadable CMX customised image?

If the former, I'd try the steps in this post first.

Good morning, I have a problem with the pre-built Raspberry Pi Image: when the new installation of CumulusMX starts for the first time it creates "Data" and "Reports" folders and also the cumulus.ini file but the owner appears to be the "root" user who however does not exist. So when I have to overwrite the aforementioned folders with those containing my data, I can't do it because the cmx user doesn't have permissions. And I can't change permissions because I can't log in as root user. Can anyone help me? Thank you

If you log in as cmx user then type
and supply your cmx user password, you become the root user.

Alternatively, prefix all your commands with sudo and they will be run as if the root user was running them. For example:

We really need to get the images changed to run Cumulus under the cmx user though.
@dazza?

yep mark im on doing this over the week end sorry been so busy with work

Any thoughts before I do this who wants Bookworm or leve it as it is?

Hi Dazza

Bookworm 64 bit works well for me on a RPi v4 and has been running since November with no issues

Solved, thanks!

Great. Don't forget to change the service config too, so that MX gets run as the cmx user - otherwise you'll experience similar issues in the future.

Edit (as root) /etc/systemd/system/cumulusmx.service so that the user and group items are changed from root to cmx.

It appears pretty straight forward installing cumulus on the Pi, but I am looking for for instructions on how to hook up my VP2 to the pi. Right now I have it hooked up to my PC with the Davis Weather Link logger. How do I get my VP2 to talk to the pi?
