### Description of my issue

Error message when upgrade apps : **grav**

Hello,

At first I wanted to use a grav skeleton, but I didn’t know how to put it on yunohost’s grav.

So I tried to download myself and copy the files to grav’s user folder.

Thank’s ! !

I tried to update and upgrade again, and now it’s good. I can’t explain why this time there was no error.
