Should I update?

[sdetweil]

@mymirror jessie is very old
4 releases back now. almost nothing will support running there now

I would also suggest some of the mechanisms to backup over the local network

Hi Sam,

yes i know :-( … very old.

in the meantime I got the system on “Stretch” and wanted to take the next step to “Buster”.
But I get the following error (on german):
PGP error: http://ftp.de.debian.org/debian buster InRelease: The following signatures could not be verified because their public key is not available …

How can I adjust/correct this?
Thanks a lot

@mymirror i do not know… buster is also not current

@sdetweil finally I tried the update: MM will not start anymore.
I am on stretch by the way.

@peter show me the messages… fromn npm start

stretch is WAY downlevel…

need to get to buster(legacy) or bullseye…

the internet keeps changing things every week… stetch is 4 years old now

[Peter]

Is it possible to update without having to start all over?
Peter

[sdetweil]

@peter maybe… as i said, stretch is really old…

I do not know if you can upgrade OS in place from stretch

pretty sure u need to upgrade node and npm too

node -v
npm -v

what pi is this ?

uname -a

@sdetweil I think it is a Pi2b.
In 2017 I built this MM and it has been running well since.
So, that is my question: update of not.
It took me very long to build, and I do not want to start all over again.

@peter do not update

@sdetweil 😁
Saves a lot of work!
Maybe I start a fresh install some day.
Thanks for your help.
Peter
