The Basics

  • Nextcloud Server version (e.g., 29.x.x):
    • 28.0.14.1
  • Operating system and version (e.g., Ubuntu 24.04):
    • Debian 12 Bookworm
  • Web server and version (e.g, Apache 2.4.25):
    • Apache/2.4.62 (Debian)
  • Reverse proxy and version _(e.g. nginx 1.27.2)
    • replace me
  • PHP version (e.g, 8.3):
    • PHP 8.1.31
  • Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
    • NCP
  • Are you using CloudfIare, mod_security, or similar? (Yes / No)
    • No

Summary of the issue you are facing:

I am using NCP v1.55.4. The system is so great at automating everything with years of problem-free operation, that I only recently realized it got stuck on Nextcloud 28.0.14.1. The server still functions somehow, but attempts to upgrade fail; attempts to use nc-backup fail. I think my SD card is dying.

I have a recent backup and my plan is to restore with a new SD card. My question is this: Do I need to use the NextcloudPi_RaspberryPi4_v1.54.3 image (which runs Nextcloud 28), restore and then upgrade NC, or can I use the v1.55.3 image (which comes with NC 30), and then restore to the previous version?

Apologies if this is the wrong place or has been answered elsewhere. The info I found was outdated (Restoring back - returns to old version of Nextcloud?). Thanks for any guidance.

I never did it myself, but I would prefer your plan as first attempt, considering to choose an usb device as boot device and leaving out the sd-card at all.

Thank you for your reply, but I’m not sure I understand. To restore an NC 28 instance, would you recommend starting from NC 28, or does it work to start with NC 30 and restore to the previous version?

Also, is there a reason you recommend doing this with a USB stick and not an SD card? I’m running NextcloudPi on a RaspberryPi 4, so I’m most familiar with booting from the SD card.

As you suggested yourself, I vote to start with that alternatiive

Start with good backups, this should not be a one shot mission but you should be able to start again and again.

Use whatever you are fine with, I prefer a ssd as boot divice for working server and take sd cards for testing.

I understand, thanks again for the help! Option 1 did work, however, I discovered the root issue. The SD card was not dying, rather, I was getting I/O errors when I tried to update or restore. This turned out to be this issue: https://forums.raspberrypi.com/viewtopic.php?t=245931

I simply moved my two external hard drives to the USB 2 ports, and everything works again on the original NC 28 instance.

Nice, thanks for the hint, keep on piing.
