[solved]Nextcloud: upgrade timed out on chmod/Incoherent package/No backup possible

Support
1

Hi,
A few weeks ago, I upgraded my nextcloud instance from 27.1.4~ynh1 to 28.0.2~ynh1. I first disabled the app not supported anymore via commande line, then ran the upgrade via the YunoHost web admin interface before going away from my computer. As I have a few hundred Gb of lots of small files in my data folder, the upgrade usually runs for a few hours.
I remember having a time out message after the upgrade when I came back, but as I had the same error in the previous upgrades and everything was working fine I did not press it further.

However, I noticed today that YunoHost still think I’m on 27.1.4~ynh1 and wants me to upgrade to 28.0.2~ynh1. And indeed, in the manifest I’m still on 27.1.4~ynh1.
I analyzed the issue and noticed that the upgrade log suddenly stops at this command:

2024-02-07 22:54:53,353: INFO - [##############++....] > Reapplying file permissions...
2024-02-07 22:54:53,354: DEBUG - + chown -R nextcloud:www-data /var/www/nextcloud

2024-02-07 22:54:56,910: DEBUG - + xargs -r0 chmod 0640

So now, if I try to upgrade the package to 28.0.2~ynh1, the upgrade fails during the backup with an error message that the source path is empty:

2024-02-18 10:29:03,801: ERROR - Impossible de sauvegarder nextcloud

If I manually try to backup the app, I have the same error.
I could try to upgrade with the no-backup option, but I’m unsure fo the results (and obviously, I can’t backup prior to try :slight_smile: )

On a sidenote as I don’t know if this is related, I noticed that if I look into /etc/yunohost/apps/nextcloud folder, I have a manifest.json file instead of a manifest.toml file, while nextcloud is in packaging v2 for ages… I’m unsure of what caused this.

So, I solved it, but it was indeed a strange issue:
In fact, even if the nextcloud instance was up to date and running flawlessly, the package itself was not updated: most of the scripts and config files were those from previous v1 packaging version (but not all of them… ).
I don’t understand why and how, but I assume this is linked to the time out during the upgrade, and after many upgrades and restore from failed upgrade over the years, it was the situation.

So, I manually updated the /etc/yunohost/apps/nextcloud/script/backup file so that the variable final_path (from v1) is updated with the setting install_dir (from v2). This solved the backup issue.

I then ran an upgrade from the comnand line (yunohost app upgrade nextcloud -- debug) that lasted for about 5 hours, and now everything is ok: instance is running and files are up to date.
