I have a new install of CumulusMX on a Raspberry Pi 4. 3.15.3 build 3173. If I start it from command line, it runs fine. I got a copy of the cumulusmx.service from the CumulusMX/MXutils/linux/ of the install, updated file path to /opt/CumulusMX/ and unfortunately it doesn't start. Any help troubleshooting this?

Here is it working from command line:

Code: Select all

 sudo mono /opt/CumulusMX/CumulusMX.exe
Cumulus MX v.3.15.3 build 3173
Working Dir: /opt/CumulusMX/
PuTTY X11 proxy: Unsupported authorisation protocol

Cumulus running at: http://localhost:8998/
                    http://192.168.1.66:8998/

  Open the admin interface by entering one of the above URLs into a web browser.

This is the file:

Code: Select all

 cat /etc/systemd/system/cumulusmx.service

And this is what I get when i try to start from systemctl:

Any Ideas what is wrong? Also if you need any other logs etc. let me know and I'll add them.

Pretty sure it's your ExecStart line - in particular this bit doesn't look correct:

-/opt/CumulusMX

I'll check mine in a tick.

Mine looks like this:

Code: Select all

ExecStart=/usr/bin/mono-service -d:/opt/CumulusMX CumulusMX.exe -service

So it looks like there is a bit missing from yours - the "d:" bit between the "-" and the "/opt..."

@freddie Thanks! That did it. I guess I assumed it was a d: from windows, so when I edited the path, I deleted it.
