MM doesnt work after update to version 2.26

[davismorehead]

sorry, didn’t know how it worked. Didn’t realize you did it.

[davismorehead]

not running headless. Just don’t have a keyboard attached to pi. so SSH intomachine.

[sdetweil]

@davismorehead I use ssh exclusively, so that’s not it. and you are running in graphical mode, w the desktop…right?

I’ve had that check in there for 3 years now… and I just checked on all my pi systems. it never fails to find the file…

[davismorehead]

i checked i don’t have that file. looking on internet it says During the booting up of the system, systemd activates default. target , which is generally a symbolic link in the /etc/systemd/system/ directory to either graphical. target or multi-user. target . It is equivalent to the default runlevel, which the system administrator used to set in the /etc/inittab file.

I don’t have graphical.target or multi-user.target but I have graphical.target.wants

[sdetweil]

@davismorehead weird

[davismorehead]

so should i try and get your script to work or do something else to fix this

[sdetweil]

@davismorehead you could try upgrade, with force instead of apply.

[davismorehead]

how do I do that?

also if I run the command
pi@raspberrypi:~ $ systemctl get-default
graphical.target

I get graphical even though I don’t have the file

[davismorehead]

I did

npm update.

i did pm2 start mm

and it works. Thank you very much

[sdetweil]

@davismorehead what npm update?

[davismorehead]

I will look at your script later.

So in the future I should run npm update not npm install?

[davismorehead]

cd MagicMirror/
pi@raspberrypi:~/MagicMirror $ npm update

added 495 packages, and changed 6 packages in 3m

195 packages are looking for funding
run npm fund for details

That worked

[sdetweil]

@davismorehead i don’t understand

when we release a new version, we have dependency changes additions, removals

so to handle all that you do
npm run install-mm
install-mm is a script tag in the package.json

it just turns off as much of the noise as we can…

my script does the same thing…

I don’t know what npm update does. we don’t use it

@sdetweil said in MM doesnt work after update to version 2.26:

ad you could try upgrade, with force instead of apply.

so based on this post i Tried npm update. Not sure what you meant me to do. So sounds like we solved it but don’t know why.

[sdetweil]

@davismorehead what I meant was to use my upgrade script

its a two step process…

test
do

on the ‘do’
its the same command as test, but with the parm ‘apply’ on the end

I check if you have already upgraded, and won’t let you do it again, accidentally

SO, as you HAVE already downloaded the new code, I would just end
but if you change apply to force
then upgrade will happen again …

my objective is to NOT screw up your wonderful mirror system .

[davismorehead]

oh. I have to figure that out since I cannot get it to run because of the default.target file not existing on my pi.

Again thanks for your help.

[sdetweil]

@davismorehead that check is only on install, not upgrade

different scripts

[davismorehead]

oh i see. Ran the upgrade script and everything worked. I didn’t apply since nothing changed. I will run it next time i need to update. Thanks again for you help. You can close this now.

[sdetweil]

@davismorehead I updated the installer (raspberry.sh) to use the

systemctl get-default 

command instead of looking at the file…

thanks for the info
