[François Pelletier]

Describe the bug

An automated backup job failed

Context

• Hardware: VPS bought onlin

Steps to reproduce

sudo yunohost backup create --apps piwigo

Expected behavior

I expect the backup to run successfully without error as it has been doing for a long time

If I'm not wrong, the error comes from

piwigo_ynh/scripts/backup

Line 31 in f26db37

 datapath=$(ynh_app_setting_get --app=$app --key=datapath) 

The backup script looks for an app setting that doesn't exist.

Indeed, this line:

piwigo_ynh/scripts/install

Line 124 in 1aa6ce5

 ynh_app_setting_set --app=$app --key=datapath --value=$datapath 

is from 2 months ago, so new installs have this app setting.

But it hasn't been added in the upgrade script (I'm going to try and create a pull request to add it).

In the meantime, I have run this command:

sudo yunohost app setting piwigo datapath -v "/home/yunohost.app/piwigo"

and the backup worked. You just need to make sure that piwigo is the correct app name for you (especially if you have multiple instances).

Thanks, it solved my issue. I ran the command to add datapath, then upgraded the application version
