Signal K update failured

[Mitch C]

Hi all,
After updating Signal K to the latest version I'm getting errors as detailed in this thread:
https://forum.openmarine.net/showthread.php?tid=4808

Are there any solutions or do I need to do a complete re-install of my setup - really don't want t have to do this as it was working so well with all the features and functions I need - took quite some time to get it setup this way (environment monitoring, engine monitor, data displays etc....)

Hope someone can suggest a solution.

Thanks,

A reinstall of node.js and sk server should get you back on track.

1) create a backup of your disk and/or the files under $HOME/.signalk (except node_modules if you want to save space)

Thanks for the reply, tried the advice in the SignalK guide, but no fet:
npm install -g signalk-server
bash: npm: command not found

It seems npm is not installed. What do I do next?

Number three

I followed number 3 which is when the npm error occurred.
Tried various other threads and google searches to resolve, but it's looking more likely a full re-install of the OS is required (as recommended in number 3 link )

Very disappointed as my system was working so well until the failed Signal K update.

Thanks for the help so far,

Do you have a backup you could burn to a fresh card & try the update again?

Unfortunately not - I'm running the system from a SSD rather than SD card - from what I can see to make a back up I would need another same sized SSD as it copies the complete SSD?
Maybe there is another way to make a system back up onto a SD card, but I've not found how to do that and never needed to until now?
If anyone can tell me how to back up to SD I'll do that once I get the system rebuilt.

Ouch! Not sure about the sd card backup, I have a bit of node red which backs up the node red flows once a day & just asked on slack if it's possible to automate saving the signalk settings somehow, otherwise I'll try to write some node red for that, think the server backup is just a zip file. At least then the server settings can be retrieved after a crash if you can get into the disk.
