emonSD-29Mar16 fail to update to 9.8.8

Hello
I am using an emonbase with low-write 9.8.7 and emonSD-29Mar16. So far I have kept updated the system with no problems. While upgrading to 9.8.8 I got the following message :

Start emoncms update:

Emoncms update started

Can anyone help me on upgrading the system ?

I believe you’ll need to update to a more current image: Your image is emonSD-29Mar16 and the current image is emonSD-07Nov16.

Glyn @glyn.hudson should confirm before going through this process.

I’ve put together a new emonSD pre build Raspberry Pi SD card incorporating many changes and some important security updates. It would be great if anyone could test the new image (@jon ?:blush:) and report back if it works ok for you. Emocms data can be migrated using built-in Emoncms backup (import / export) module: Import / Backup - Guide | OpenEnergyMonitor Full emonSD changelog & Download page (Wiki) emonSD-07Nov16 BETA File System Stick with 4GB min SD card (8GB+ recommended).

Thanks for your reply.
Is there any instructions on how to upgrade a running image or is it necessary to make backup , erase running image, install the new one and restore backup ?

There is no upgrade for a running image. You do need to make a backup, create the new image, and restore backup.

I’d suggest saving your current SD card as a backup and locating a new or gently used SD card for the emonSD-07Nov16 image. If something goes wrong then you’ll have the original.

Somewhere on the OEM site there are migration instructions for making a data backup with your current running image. Getting the new image written to a blank SD card using Etcher, and then importing the data to the new image. I’m having trouble locating that info at the moment!

You may want to look thru the Guide and the Resource areas. I’ll repost if I stumble across the info.

I will definitively follow your suggestion to use current sd card as backup.
Thanks a lot for your time

Do you suggest to run periodically a “sudo apt-get dist-upgrade” command after installing emonSD-07Nov16 image to keep linux base system updated ?

Jon · 2017-08-22T23:24:03.550Z

After installing emonSD-07Nov16 - Yes. But I don’t run periodically update/upgrade. I usually leave update/upgrades for when I am upgrading lots of other things (e.g., node-red, etc.) and I have time to spend on any issues. And after doing a backup!

gmaui · 2017-08-22T23:32:20.689Z

I see your suggestions. Thanks again for your consideration.
