The Basics

  • Nextcloud Server version (e.g., 29.x.x):
    • 31.0.1(upgrading to 32.0.8)
  • Operating system and version (e.g., Ubuntu 24.04):
    • Ubuntu 24.04 LTS, all updates applied
  • Web server and version (e.g, Apache 2.4.25):
    • Apache 2.4.58
  • Reverse proxy and version _(e.g. nginx 1.27.2)
    • None (using CloudFlare for Internet access but problem happens using command line on server)
  • PHP version (e.g, 8.3):
    • 8.3.6
  • Is this the first time you’ve seen this error? (Yes / No):
    • No, facing the same for each upgrade
  • When did this problem seem to first start?
    • every time I try to upgrade
  • Installation method *(e.g. AlO, NCP, Bare Metal/Archive, etc.)*manual installation
  • Are you using CloudfIare, mod_security, or similar? (Yes / No)
    • CloudFlare tunnel

Summary of the issue you are facing:

Using both web updater or command line updater, process freeze or fail on step 4, downloading upgrade zip file.

I try to download the file manualy using wget (also from server) and I was able to obtain file (takes some hours).

Would it be possible to have an upgrade option that allow to manually download the zuip file in a location that can be identified by upgrade process? Upgreader would then use the file without trying download.

Steps to replicate it (hint: details matter!):

  1. run sudo -E -u www-data php /var/www/nextcloud/updater/updater.phar

  2. Choose yes to perform upgrade

  3. Step 1 to 3 proceed

  4. Step 4 either freeze forever (require to kill process after many many hours) or exit with:
    ”[✘] Downloading failed
    Curl error:

    Update failed. To resume or retry just execute the updater again.”

Tips for increasing the likelihood of a response

  • Use the preformatted text formatting option in the editor for all log entries and configuration output.
  • If screenshots are useful, feel free to include them.
    • If possible, also include key error output in text form so it can be searched for.
  • Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.
