Update 4.1 -> 4.2 is not working

[TomWoB]

Hi Tim,

the update SSH-command seems not to work on my Pi:

pi@moode:~ $ sudo /var/www/command/updater.sh r42

[update-r42.zip]
  End-of-central-directory signature not found.  Either this file is not
  a zipfile, or it constitutes one disk of a multi-part archive.  In the
  latter case the central directory and zipfile comment will be found on
  the last disk(s) of this archive.
unzip:  cannot find zipfile directory in one of update-r42.zip or
        update-r42.zip.zip, and cannot find update-r42.zip.ZIP, period.
chmod: cannot access 'update': No such file or directory
/var/www/command/updater.sh: line 35: update/install.sh: No such file or directory
Update cancelled
pi@moode:~ $


Any suggestions ?

Its an in-place update for moOde 4.2 only. There is no update for 4.1 -> 4.2. moOde 4.2 has to be build from scratch because its based on a completely new version of Raspbian.

OK ... I misunderstood something, but I hope it's sometime possible to do minor updates like 4.x -> 4.y via an "in-place update", because you have some steps to do in case of your Pi

• is part of an Audiophile Setup without keyboard, mouse and display
  
• has > 120 GB music on SD-card (which will be overwritten)

Hi Tom,

Generally, minor updates can be packaged so they can be applied in-place but 4.1 -> 4.2 was quite a major upgrade including a new OS and many new core components making it virtually impossible for me to create a reliable in-place upgrade solution.

Either way though, anytime you store music on the OS drive there is a risk that at some point a new OS
will need to be written to the card. Maybe try one of the compact USB drives like a 120GB Sandisk Ultra Fit. That would allow you to maintain your music files separate from the OS.

Hi Tim,

I understand the update problem with a new Raspian version, but e.g. Windows 10 can do "nearly a complete new Operating System in-place update" every 6 months (Threshold, Redstone updates), but this is more a Linux&Raspbian topic.

And ... I have already most of my music files on an external SSD within an external enclosure: ICI BOX IB-233U3-B . That's fine for

• iTunes files (*.m4a)
  
• ripped CDs (*.flac)
  
• HDtracks up to 96kHz/24bit (*.flac)
  

For HDtracks files >= 192kHz/24bit I prefer to store them on the local SD-card, because it happened sometimes in the past that such files stuck for a short time (< 1s). OK, very seldom cases, but that's not acceptable for me ...

lol, companies like MS and Apple prolly spend >100 million per year on developing, testing, distributing and supporting their OS upgrades.

I think our little moOde project does pretty well in comparison.

Hi Tim, I realized yesterday to still have Moode 4.1 running on my RPi3-based network streamer. I saw that is a major update, so no update is possible from console through SSH. I suppose that I need to prepare a plain microSD and start from scratch a new configuration. Is there a way to make a backup of the Moode settings to restore on the new 4.2 version?
thanks
Andrea

Hi Andrea,

Developing a settings migration system is a major undertaking and thus is still quite a ways down on the TODO list.

..reading the guide, it seems that I have first to prepare a microSD with 2018-06-27-raspbian-stretch-lite.img, then boot the raspy from it. How can I access to it through SSH to going forward in the installation path? With user and pwd? I try user pi and pwd raspberry but putty denied the access...

[mancio61]

..or better... I'm able to ping the Raspy from my PC, but Putty (or WinSCP) doesn't reach it! ("Network Error! Connection refused").
I successfully establish SSH connection with other two RPis on my LAN (running LibreElec), so I assume that the network is OK.
