Nextcloud upgrade repeated failure due to incompatible NC apps with v32 (but thankfully clean restore now)

tzb6js · March 3, 2026, 10:49am

What app is this about, and its version: Nextcloud 31.0.11~ynh1
What YunoHost version are you running: YunoHost 12.1.39 (stable).
What type of hardware are you using: Old laptop or computer

Describe your issue

I am unable to uograde my current version of Nextcloud. In the past this was always a simple one to upgrade but that is no longer the case. I have made sure that all Apps within Nextcloud are up to date, all my YNH is up to date and all is working well. However, every time I try to upgrade it fails. Previously the automated restore from backup would fail but that now seems to be fixed after I applied som other fixes (e.g. Yarn key) . I’ve hit a bit of a brickwall and can’t see anything similar in other cases. Any help is really welcomed!

I just spotted this buried in the logs “installed_apps_not_compatible_with_future_version=”. Now I do seem to remember another case on here refering to something similar and mentioning some setting you can apply through the Nextcloud UI to highlight these Apps but I cannot find any such switch. Has anyone else seen this before?

Based on another item in here I ran this command (from Alexs) to see what app are active in Nextcloud:-
cd /var/www/nextcloud

sudo -u nextcloud php --define apc.enable_cli=1 occ --no-interaction --no-ansi app:list

This gives me a list of active and deactivated apps (below) but how do I know which one is causing the issue?

I see there is a command to delete an app on the CLI (below) but how do I know which one is the problem (and hopefully is one I won’t miss).

cd /var/www/nextcloud

sudo -u nextcloud php --define apc.enable_cli=1 /var/www/nextcloud/occ app:remove APPNAME

example:-

sudo -u nextcloud php --define apc.enable_cli=1 /var/www/nextcloud/occ app:remove breezedark

tzb6js · March 3, 2026, 11:34am

I wonder if I can spot the culprit on here:-

tzb6js · March 3, 2026, 11:44am

I found a match !! app_api . But what does it do and can I live without it? I suppose there is only one way of finding out…

I have disabled the App called app_api in the Nextcloud app interface. Let’s see if I can live without it operating for a day and then see if the upgrade works. If not I can use the command to remove the app from Nextcloud. I suggest the latter as I see upgrades sometimes fail if an app is incompatible and disabled !

Of course, it could be that I do need this app and I suppose I will then have to avoid upgrading until the app developers have upgraded their code to be compatiblle with Nextcloud v32 .

tzb6js · March 3, 2026, 12:02pm

It all seemed to be working OK so I couldn’t wait and tried the update again. This time it failed with a fairly fundamental problem. Not sure what is wrong, perhaps I will try again later.

tzb6js · March 3, 2026, 12:34pm

Well the update worked better BUT still the same problem. It looks like I may need to manually remove the app as just disabling it doesn’t help.

tzb6js · March 3, 2026, 3:39pm

Darn it, I cant delete that app either with or without it being enabled. Apparently it’s a “shipped app” so can’t be deleted. Yet if I am correct and thats the app that is stopping the upgrade then I’m stuck.

Result with it enabled:-

root@giliker:/var/www/nextcloud# sudo -u nextcloud php --define apc.enable_cli=1 /var/www/nextcloud/occ app:remove app_api
app_api could not be removed as it is a shipped app

And result with it disabled:-
root@giliker:/var/www/nextcloud# sudo -u nextcloud php --define apc.enable_cli=1 /var/www/nextcloud/occ app:remove app_api
app_api is not enabled

Has anyone got any suggestions? Have I gone down a rabbit hole? Is there a simple answer?

Hi, i think you are on a wrong way.

I think the update is blocked on line 124 of thé upgrade script:

github.com/YunoHost-Apps/nextcloud_ynh

scripts/upgrade

579776369


      
          if [[ "$last_major_version" != "$current_major_version" ]]
          then
              installed_apps_not_compatible_with_future_version="$(list_installed_apps_not_compatible_with_future_version $last_major_version)"
              if [[ -n "$installed_apps_not_compatible_with_future_version" ]]
              then
                  ynh_die "The following apps are not (yet?) compatible with Nextcloud $last_major_version. You should make sure to upgrade the app, or disable it, or wait for it to become compatible before running this upgrade : $installed_apps_not_compatible_with_future_version"
              fi
          fi
          
          # Keep the attribute choose for ldapEmailAttribute
          ldapEmail=$(exec_occ config:app:get user_ldap "${ldap_config_prefix:-}"ldap_email_attr)
          if [ "$ldapEmail" = "maildrop" ]
          then
              ldap_email_attr="maildrop"
          else
              ldap_email_attr="mail"
          fi
          
          # Before NCv32, Yunohost was not using any prefix for the LDAP config.
          # This is now mandatory so we need to create a new config with a prefix.
          if [ "${ldap_config_prefix:-}" = "" ]

Dont panic

tzb6js · March 3, 2026, 10:00pm

Ahhhh. That looks promising. Well spotted! Cheers Marc.

What would be the way forward? Disable the ldap mail or somehow upgrade it?

JfmbLinux · March 3, 2026, 10:05pm

Trick:
Other method with next command:
yunohost app shell nextcloud

To know the list of installed and activated apps
php occ app:list --enabled

To find out the list of apps installed and disabled
php occ app:list --disabled

To exit the shell:

exit

marc · March 3, 2026, 11:41pm

try again the last command :

sudo -u nextcloud env PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin COREPACK_ENABLE_DOWNLOAD_PROMPT=0 NPM_CONFIG_UPDATE_NOTIFIER=false php8.3 --define apc.enable_cli=1 occ --no-interaction --no-ansi config:app:get user_ldap s02ldap_email_attr

Marc, I ran that command through an SSH terminal. It seemed to work OK, at least no errors appeared. I then ran the upgrade from the YNH UI. Sadly it failed “An error occured inside the app upgrade script”.

Error: "500"

Action: "PUT" /yunohost/api/apps/nextcloud/upgrade

Any other suggestions? Your support is appreciated.

Thanks for this Jfmb. Cheers.

This may help:

tzb6js · March 4, 2026, 9:14pm

Otm, that seems to make sense to me but I am not sure how to use this insight. Is it something that needs to tweaked in the YNH upgrade script for NC v32. I am still an amateur on Linux (I did code on Unix with Cobol, Pascal and Coral-66 a lifetime ago) but I’m not sure how to use this insight. Any advice…

marc · March 4, 2026, 9:47pm

Well, in the post transferred by @otm33 , there is nosolution yet.

I don’t understand why your script stops. It says that you ldapEmail is void, but it should continue.

Let’s control you upgrade script.

Please can you share it?

sudo yunohost log share /etc/yunohost/apps/nextcloud/scripts/upgrade

And we should also control nextcloud log:

sudo yunohost log share /var/log/nextcloud/nextcloud.log

And php log

ls /var/log | grep php8.3

otm33 · March 4, 2026, 11:06pm

Do you have empty servers conf in LDAP/AD Integration tab ?
