How to upgrade a Linux "server" with minimal modules?

[sdetweil]

@ember1205 by default, install puts down all the code, with three different start options

// server only - probably what you have now
npm run server

// npm start, npm run start , npm run start:x11, npm run start:wayland (last two in latest releases)
// launch UI, thru embedded electron browser or browser on system thru my browser over server setup
npm run start

// or client
npm run client

the latest releases will need a new OS, and new JS, and a new …

one thing you can use to move between environments, is my backup/restore scripts.
https://github.com/sdetweil/MagicMirror-backup-restore

which backup the config.js, custom.css (and any other files related)
and the list of modules installed… NOT the BINARY

this backup can be placed on github, so you don’t have to store it on the local machine
storing with git, also allows you to keep track of changes/versions of your setup

because it is NOT a binary, you can use it to transition to new SD cards, or new systems (pi->minipc…etc)
backup here, restore there
restore assumes MM is installed and runnable…

as an example
backup now, save to github (still free today)
make new sd card,
boot
install MM
then run restore to put saved config and modules on the new system

you can run the backup/restore by copy/pasting the links and adding parms if need be (like push to repo, not default)

in the meantime, you can just change the start command from run server to run start to start the MM ui on the same machine (needs a head of course)

ps. you cannot upgrade ONE feature and not others… its all or nothing

we ALWAYS start the server, and sometimes start the UI depending on the command used
but the files are all one instance at the same version

[sdetweil]

@ember1205 I recommend

make a backup, store to github
make a new SD card, latest OS
install MM, verify it starts (full service, UI etc)
run restore from github to restore your configuration and modules…
restart and verify

old system is untouched

@sdetweil Thanks for the response.

I’m familiar with the different options that come with a new install and would be ok with having to DO a new install if that’s the only way to get upgrades completed. I guess I’m wondering if there’s a simpler way to upgrade the one or two modules that I have and get the core MM upgraded as well without having to start from scratch with the configuration and such. This instance is server only (there’s nothing attached to any sort of output here, and I don’t even run MM as the client any more - it’s a linux shell with its own GUI, auto-starts firefox in kiosk mode, and the page is set to always launch the mirror address).

I’m not even concerned with how to back everything up because my installation is actually fairly simple. And I’m not actually looking to change environments - I’ve already done that from a short while back. This is all entirely for the server side which is a linux guest running on a XCP-NG virtualization host.

@ember1205 the difficulty is that the core has been kept up to date, and it requires new system parts that require new system parts…

you MUST upgrade nodejs if not on node 22
upgrading on older systems fails, the next node upgrade, 24 or above, drops support for 32bit systems completely… we are holding off as long as we can… but the clock is ticking…

my install and upgrade scripts enforce the systems path… if they fail now, there is no manual way to get there from where you are… (without rebuild)

and if you use my installer script, its a copy/paste… not a lot of work

make the backup regardless

[sdetweil]

@ember1205 you can attempt to upgrade modules…

each is separate

cd module_folder
git pull
if successful, npm install

restart mm… to load the new modules…

only a few have latest as dependencies… which would force all the above work

[sdetweil]

@ember1205 upgrade of the core code is

cd  MagicMirror_folder
git pull
npm install

if it will run… needs at least node 22.22.1

let me know how I can help

you can fall back to a prior version by switching to one of the earlier releases, thru the git tag we created.
if you try the upgrade (manual) and it fails and want to try this, let me know i’ll provide the commands needed

@sdetweil I am running (currently) on opensuse Leap 15.6. I will be updating in the not-too-distant future to Leap 16.0.

In looking at the installed packages, Node.js lists “22.22.0” as the package but “22.15.1” as the installed version. So…

zypper ref ; zypper up

Let it install all of the pertinent updates… Reboot (new kernel was part of the updates)… Everything is back online. Checking the installed software list now shows Node.js as “22.22.0”.

Leap 16.0 will allow me to go to Node.js 24, but that would be an undertaking for later today or later this week (depending on what time I might have elsewhere).

Updating the modules went fine (overall). This is what a git pull in the main MM directory shows me:

Update…

Updating the modules crashes the server. So, I’m going to have to get the main server updated… I had to revert to a prior snapshot to get the MM server running again.

[sdetweil]

@ember1205 said:

package-lock.json
package.json

erase those and git pull again

[ember1205]

@sdetweil I’ll have to try again a little later today maybe… I had to revert the snapshot (removing the module updates) to get it running again.

[sdetweil]

@ember1205 understand… please advise your results when you can
