My YunoHost server

Hardware: HP Proliant DL360 64BIT PLATFORM
YunoHost version: 11.2.29
I have access to my server: Through SSH and the webadmin
Are you in a special context or did you perform some particular tweaking on your YunoHost instance?: Yes
If yes, please explain: The YunoHost instance is installed on an HP Proliant DL360, which is behind a VPS. I encountered issues while trying to restore a web app (my_webapp__2) and had to manually intervene in the restoration process.

Description of my issue

I found out that my website hosted on my_webapp__2 was giving 404 errors on subpages. To resolve this, I decided to restore a known working backup. However, the restoration process failed.

1. Initial Attempt to Restore:

  • Issue: The restoration process failed (as indicated in the YunoHost error log). I attempted to restore another backup, but that also failed.
  • Actions Taken:
    • I downloaded the backup file and manually checked its contents. I noticed that all files were present except for settings.yml and config_panel.toml.
  • Outcome: The absence of these files indicated that the restoration process couldn’t be completed successfully.

2. Manual Restoration Process:

  • Actions Taken:
    • File Restoration: I manually restored the missing files by copying them from another app (my_webapp__3), which had similar configurations.
    • Configuration Files Involved:
      • /etc/yunohost/apps/my_webapp__2/settings.yml
      • /etc/yunohost/apps/my_webapp__2/config_panel.toml
      • NGINX config: /etc/nginx/conf.d/compannie.com.d/my_webapp__2.conf
      • PHP-FPM config: /etc/php/8.2/fpm/pool.d/my_webapp__2.conf
  • Outcome: The files were successfully restored and adjusted, but the app did not appear in the YunoHost user panel.

3. Adjusting Permissions and Ownership:

  • Actions Taken:
    • Set permissions and ownership to ensure the web server could access the app files:
sudo chown -R www-data:www-data /var/www/my_webapp__2
sudo chmod -R 755 /var/www/my_webapp__2
  • Outcome: Permissions were set correctly, but the app was still not visible in the user panel.

4. Regenerating YunoHost Configurations:

  • Actions Taken:
    • Regenerated YunoHost configurations using:
yunohost tools regen-conf --force
  • Outcome: After regenerating the configurations, the app became visible in the YunoHost admin section but wouldn’t load correctly when accessed.

5. Managing App Permissions:

  • Actions Taken:
    • Attempted to add permissions for users to access my_webapp__2 using:
yunohost user permission add my_webapp__2.main -g visitors
  • Outcome: Commands did not execute as expected, possibly due to syntax issues or YunoHost version limitations.

6. Consulting Logs and Forums:

  • Actions Taken:
    • Checked logs:
      • NGINX logs: /var/log/nginx/error.log
      • PHP-FPM logs: /var/log/php8.2-fpm.log
      • YunoHost API logs: /var/log/yunohost/yunohost-api.log
    • Looked up related issues on the YunoHost forum.
  • Outcome: Logs provided insight into errors, but no definitive solution was found.

7. Backup Restore Error Encountered:

  • Issue: During the restoration of my_webapp__2, I encountered an error where the restore process failed due to a missing db.sql file, even though a db.sql* file was present.
  • Error Log:
2024-08-31 15:39:49,609: WARNING - /var/cache/yunohost/app_tmp_work_dirs/app_3fu6bkqt/restore: regel 32: ./db.sql: Bestand of map bestaat niet

2024-08-31 15:39:51,112: ERROR - De app 'my_webapp__2' kon niet worden terug gezet: Er ging iets mis in het helstelscript van de app
  • Context:
    • The backup system was not creating backups of certain files correctly, which led to issues during the restore process.

Request for Help:

Despite following these steps, my_webapp__2 still does not load correctly in the YunoHost user panel, and I encountered an error during the restore process. I need guidance on how to resolve this issue, whether it’s related to permissions, visibility settings, or the backup/restore process.

Any insights or suggestions would be greatly appreciated. Thank you!

I have had something similar, there was a version with an error with db.sql* but it have been fixed here :

Perhaps you can just try found were the db.sql* file is in the tar backup and rename it to db.sql…

In my case I have resinstall a my_webapp, sync files I have backup before, give them the correct permissions and do an manual import of the db…

Normally the owner is my_webapp: but perhaps your application need www-data ?

If I do that I get this error:

Could not load info for archive '/mnt/backup/my_webapp__2-pre-upgrade1.tar.gz'… The info.json file cannot be retrieved (or is not a valid json).

The info .json in inside the root of the backup folder is the same as inside the .tar.gz backup file.

To fix it now, I reinstalled the app as a new one, then I moved the files from the backup in var/www/my_webapp__2 did the database thingy and it was fixed. No thanks too the backup bug!

Ok,
if you still have your file my_webapp__2-pre-upgrade1.tar.gz perhaps it needs also found inside the the path apps/my_webapp__2/settings/scripts/backup and correct the typo db.sql* to db.sql…

Well not easy, we have been both unlucky with this very short “star from nowhere”…

Nice if you have found how resolve it.
