Summary of the issue you are facing:

I had a problem with data directory and had to delete most of it, did occ scan all after, the server works ok but it says there is a new version available. When i click open updater it goes to https://hostname/updater but the page is just a blank white page.

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

  1. Go to admin overview
  2. click “open updater”

Have you updated using the web-mode of the Updater before? (There are a couple ways to do updates).

Does anything appear in your browser inspector under either Console or Network when you click the button to access the updater?

The Updater logs to a file called updater.log located within your data directory. Please check that for clues (though if there are permissions issues, which is possible given you state you had “a data directory problem”, maybe that’s related. So you may also want to check your web server error log.

I had a problem with data directory and had to delete most of it,

What sort of problem?

Yes, i have been doing it since nextcloud 16 in 2020, it worked flawlessly except once in like 2022 where it bugged while upgrading and i just had to occ upgrade and it finished, after that i had no problems until now.

“GET https://cloud.casianf.com/favicon.ico 404 (Not Found)” this is all that appears in console and in network its the updater followed again by this with 404

i checked the logs, it shows the last update that i did to current version in September but nothing regarding this update, i didnt even click to update for this version, because the page is empty.

I was very unlucky on having a bad drive and also a stick of ram fail and my raid array was in a very bad state (i only had my nextcloud data directory here), the only way i could save it was to offload most of my data directory off the server, create a new raid array as the current one was unsalvageable and put back the data directory and give back permissions and change the data directory in nextcloud and rescan the files.
Nextcloud runs just fine now, i can do everything i did before, have apps like recognize running successfully but this is the only thing that does not work.

Can you try running the command-line mode of the Updater?

Same folder, but from the shell: Maintenance: Command-Line Updater.

Oh wow, I just went to run it, the file itself exists but after running the command nothing happened, I opened the file with editor and it is empty. I assume that is the problem? The file contains all the steps for the upgrade I assume. That is weird as I have not done anything to the nextcloud install folder other than change the data storage location in the config file after the unfortunate series of events.

I assume that downloading the “updater.phar” file an trying again is the next series of events? Or should I just do the manual upgrade? Like rename the nextcloud install folder, download the updated one and then move the config files from the old one to the new one and all the other steps in the manual upgrade guide?

I assume that is the problem?

Definitely sounds like you’ve found the culprit.

I assume that downloading the “updater.phar” file an trying again is the next series of events?

Yes, that would be one approach. Just pull it (and the rest of the contents of the updater/ folder from the Archive (tar.gz or zip) of the matching version you already have installed.

Or should I just do the manual upgrade? Like rename the nextcloud install folder, download the updated one and then move the config files from the old one to the new one and all the other steps in the manual upgrade guide?

That would also work.
