Hello there,
While working on upgrading Cheky to the lastest version., it appeared that the way to manage the upgrade does not work anymore (See https://github.com/YunoHost-Apps/cheky_ynh/blob/4.4.1/scripts/upgrade#L127) as there is a change in the database model.
When an upgrade is available, there is a button in the webinterface admin panel to click to run the upgrade. I tried to use wget to run the exchanges between my web browser and Cheky but it fails.
I made a post on the project forum and got a reply by the author with a hint to do it in php (here for post and wget commands (in french))
Somebody has experience or tips on this?
Hello there,
I have been able to integrate the php file provided by the author of Cheky inside Yunohost but it does not work as expected 
If Yunohost does the upgrade, it doesn’t work because it cannot find the command
root@yunohost:~# sudo yunohost app upgrade cheky__2 -f /var/tmp/foo/cheky_ynh/ --debug
[...]

If i launch the command manually by SSH, it works
root@yunohost:~# chown -R cheky__2: /var/www/cheky__2/
root@yunohost:~# sudo -u cheky__2 /usr/bin/php /var/tmp/pipo/upgrade_cheky.php /var/www/cheky__2
root@yunohost:~#
My guess is that there is some $PATH or other weird issue. Someone had to figure out a similar issue ?
Code
So…
First I think you should copy your script into $finalpath, so it would be at the right place to work.
Also, try without the double quotes, it probably make the entire command looks like a entire path.
Make sense and it runs now. Thanks
