After 1.2.9 update via snap, error while loading shared libraries: libatomic.so.1

another time the automatic snap update stops the instance
only revert to latest version helps and node-red runs again

how to fix the issue on my devices?

~ $ sudo snap revert node-red
node-red reverted to 1.1.3

  Node-RED is a Flow Based Programming tool written in node.js and using a web front end for wiring
  together hardware devices, APIs and online services in new and interesting ways.

  Many extra nodes are available (see http://flows.nodered.org), and can be installed via the Menu -
  Manage Palette option. Due to the restrictions of snaps nodes that require extra access to files,
  ports, or have a binary component, may NOT work or install correctly.

  For more information see the
  [README](https://github.com/dceejay/nodered.snap/blob/master/README.md).

  Now based on Core18.

  The edge channel contains auto-built versions of the  package. The beta channel may contain
  beta/next versions (when available).
commands:
  - node-red.desktop-launch
  - node-red.npm

the latest release with bumpted node-js fixed the issue (revision 677)

~# snap list
Name       Version   Rev   Tracking  Publisher     Notes
node-red   1.2.9     677   stable    noderedteam✓  -

Well that is actually backwards nodejs. Will be unsupported in April

How I can help to investigate the issue? For now it seems to be a temporary solution with nodejs.

Can I test the updated nodejs for you?
(Monitor file access for the whole process to check the path for not found libatomic.so,. Just an idea)

I am the only one with this issue?
Or the second time the fastest reporter?

Well the "broken" one with nodejs14 is in the snap beta channel so can be loaded and investigated if you like.

Actually a bug in snap config for nodejs - being tracked here

testing on another RaspberryPi and same error is there (revision 673, raspbian 10 instead 9), but something is strange

'snap start node-red' doesnt work (libatomic error)
but manual start works (adopted the startNR file in bin folder to command)

is there an official command to manual start node-red with snap package (without snap command?)
for now i dont know where to look further

# ./snap/node-red/673/bin/node /snap/node-red/673/lib/node_modules/.bin/node-red -u "/root/snap/node-red/673/" "$SNAP_USER_DATA/flows.json"

Have you also updated the snap core ? sudo snap install core ? Then stop and restart node-red

The system was up to date before I started to test on this RPi. apt update and upgrade and then installed the snapd package.
core18 was downloaded automatically with install of node-red

I see a 673 there - the latest in stable should be 677.
673 is in beta channel and uses nodejs 14 - but needs core 2.49.1 which hasn't been released yet. (as per my link to their repo above)

The problem is not new

edit:
i have sent you login credentials for the debian 10 raspberry pi to check the things out.
for now it looks like a bigger problem (two similar debian 9 installed raspberry pi's and a later installed debian 10 raspberry pi) with arm based computers?

Looks like it. - Much easier to install native or use docker in the meantime.
Will raise an issue and see what happens/

OK - there is now a version in edge channel that fixes the atomic issue - but that then hits the EPERM issue already raised that needs the fix above... so no more to be done I think for now.

thanks for the support
revision 686 in edge channel works for debian 10 and runs fine so far (except the EPERM error)

i will have eyes on my PLC's with debian 9 if the final update comes there :slight_smile:
and i hope there are no breaking problems in future releases

without node-red i can't light up my home
it was the only easy to use software for all needed purposes and i'm happy with it
others will say, don't touch a running system, but network accessible services need the latest patches.
