hmmmm. apt tells me I have the newest versions. how do I get the updated version of NPM?

You install using NVM rather than the OS versions. This is pretty standard for Node across the board because it is so new.

Don't understand why it won't update????

@pmoncho maybe because you are not on a supported version of Node, and NPM is based on Node version, so you need to update Node to update NPM.

I just followed the instructions in the MC guide.

I will look into NVM too.

Which is fine on its own, but limits you to the versions of NodeJS and NPM that come with the OS. You want one that is newer, which is not something that MC sets up for you. So in the one case you are following the instructions, but now you are not, so the mix is causing an issue. I never use NodeJS from the OS because it always causes problems for me (any OS, nothing to do with Ubuntu.) I've found that having version control is critical in the Node ecosystem. But MCs goal is to walk you through only enough ecosystem setup to get their app running.

I will keep this in mind for future deployments.

I have NVM installed, now using 6.9 of NVM and v12.2.0 of node. The npm error is now gone but the original problem still exists.

Will continue hunting.

Let's see the config file.

I believe you want the config.json file. Its a pretty generic file.

@pmoncho in your original post, you said that MC was moving itself to a different port. But in your netstat, MC wasn't running. What port is it going to?

pmoncho

@scottalanmiller said in Ubuntu 19.04 upgraded from 18.10 - Meshcentral not redirecting port 80:

is it goin

My apologies. It is going to 1024 and https to 1025.

That is the weird part. If something was hogging port 80, I would understand the move to higher ports as that is what MC does. Nothing shows on port 80 at all so that is what I cannot figure out.

Plus I know you had it working on U 19.04 so I was gungho for the upgrade.

I wonder if you need do this?

Did you forget to run as root? Those are unprivileged ports.

scottalanmiller

If you run as non-root (I know the new directions seem to point people to avoid this, but the ones we used when everyone originally got this up and running all pointed us to use root) you have a lot of additional complications that you likely want to avoid. I highly recommend sticking to root for almost anyone deploying this.

That did it. Ugh. I totally forgot about this because I upgrade from 16.04 to 18.04 to and then to 18.10 and did not have that issue. Apparently I now have that issue.

Thanks. Boy, I did learn alot over the last two days. Now I have a go to check in the future..

That setcap setting is "by the version", so if Node updates, the setting would need to update.

I do run as a non-root user. I will probably install as root in the near future. I installed as non-root as it seemed more secure but I do see the issue that it presents also.

Thanks for the help.

Thanks. I thought it was a OS thing. I didn't put 2 and 2 together. Ugh. I know better now.

Installing as root is one piece, running as root is another. You should be able to just run the current install as root to fix at least that problem.

I would need to move it outside of home dir to something like /opt?

Should, of course. No software ever goes in the /home directory. But need to? No, root can use any directory.
