Cloudron is offline reconnecting - Happened after OS upgrade

[makemrproper]

Problem description

I cannot reach the control plane of Cloudron!

Context description

I just upgraded my VPS from Ubuntu 1604 to 1804 after Cloudron recommended it.

The OS upgrade went well. I followed the instructions provided by you after a VM snapshot. All good. lsb-release -a now shows 1804. Next stop 2004. But not before I fix this issue, and snapshot my VPS again.

Runtime environment description

Ubuntu 1804 Ubuntu untouched vanilla, upgraded from 1604 untouched vanilla.
My containers are up and running, and I can reach them.

Deep down in the bowels of Nodejs forums I encountered that it could have something to do with a NodeJS module that needed to behave according to a certain version. Source: https://github.com/TrilonIO/angular-application-insights/issues/31

Question / request for hlep
Any help on this would be much appreciated!

Some analysis:

Is this an npm cache issue? should I clear the npm cache? How do I do this? Invoke npm cache clean?

@makemrproper Not seen that error before. But it seems that maybe nodejs got downgraded or something. Can you see the output of node --version ? It should be 14.15.4

[girish]

The error seems to be coming from the use of util.types.isPromise in the code. https://nodejs.org/api/util.html#util_util_types says it was added in node 10. So, maybe node is something < 10 ?

@girish

Output of node --version:
v8.10.0

npm cache verify states:

| New major version of npm available! 6.14.10 → 7.20.3 │
| Changelog: https://github.com/npm/cli/releases/tag/v7.20.3 │
│ Run npm install -g npm to update!

You were spot on

@makemrproper Cloudron installs nodejs from nodejs.org itself and not from ubuntu. So, maybe this was just some leftover from your previous installation (?) . Anyway, you can uninstall nodejs entirely. apt remove nodejs. Then, you will find Cloudron's nodejs in /usr/local/node-14.15.4 . Just ln -sf /usr/local/node-14.15.4/bin/node /usr/bin/node. Then, if node --version gives the correct output, do systemctl restart box .

@girish Boom! Back up and running
Well this was a joyous outcome. Thanks a bunch Girish!
