Update and backup of YH Hubzilla 8.6 package did not work

[rockyIII]

Hardware: VPS online

YunoHost version: 11.2.3

I have access to my server : Through SSH | through the webadmin | direct access via keyboard / screen |

Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : no

Description of my issue

After a not correct working update from YH Hubzilla 8.4.1 to YH Hubzilla 8.6 and deleting of the HZ App - the resorting of the backup did not work

---

First the installation seamed fine but the HZ queueworker was not doing anything so that no posts could be sent.

After the support of a HZ DEV we found out that the HZ Composer which needs PHP version >= 8.1.0 gets on my YH server just php 7.4.33 provided.

than i tried to restore the hub installation to the last working installation with the automatic made backup by YH but also that was not working. I got this warning

WARNING - /var/cache/yunohost/app_tmp_work_dirs/app_mvszbjej/restore: line 30: db_user: unbound variable

and here is the full log:

I hope very strongly the backup can be still used an be reinstalled and my hub is not lost. Please tell me what i your try.

Thank your very much for any help in this topic. I really appreciate all your great work you do for YH

the backup could be restored now

Took me a while to understand how to do it but now i found a fix.

During the YNH backup process somehow the variable “db_user” was not stored - it is missing in the file “settings.yml” where all the variables are stored in for restoring a YNH app backup file

So here is what i did and what you can try if you came in to a similar situation:

---

YNH App backup archives are stored in /home/yunohost.backup/archives/

With your SFTP client make a save copy of your not working backup archive to your local hard drive - just in case…

Rename the backup archive on the server from “hubzilla-pre-upgrade2.tar” to something like “hubzilla-save.tar” so that YNH will not overwrite this archive by any other backup operation.

Go by ssh to /home/yunohost.backup

$ cd /home/yunohost.backup/

extract the file “settings.yml” from the backup .tar archive

$ tar -xf archives/hubzilla-save.tar apps/hubzilla/settings/settings.yml

(all this tar commands will take a while, depending how large your archive is, so be patient till the operation is done)

You find the extracted file under /home/yunohost.backup/apps/hubzilla/settings/settings.yml

Edit the extracted file “settings.yml” by adding the line “db_user: hubzilla” and save the file.
My SFTP client can do this within the app. If your SFTP Client can’t do this you have to first download the file, use a text editor for editing, and upload it again by SFTP.

Delete the original file “settings.yml” whin the .tar achieve

$ tar --delete -f archives/hubzilla-save.tar apps/hubzilla/settings/settings.yml

add the new edited file “settings.yml” to the .tar achiv

$ tar -uf archives/hubzilla-save.tar apps/hubzilla/settings/settings.yml

Now the YNH restore script can find the variable “$db_user” the and the restoring of the backup archive will work. Just select the renamed archive in the YNH webAdmin interface

or do in this case (archivename = hubzilla-save ) by command line

$ yunohost backup restore hubzilla-save --apps hubzilla --debug
