What type of hardware are you using: VPS bought online
What YunoHost version are you running: 12.0.6
What app is this about: calibre-web
Describe your issue
I mistakenly upgraded calibre-web to the last version, which I did not want because I made specific modification to the translation and css of the previous installation.
And when I tried to restore the backup it failed (the logs are below). Something to do with pip or python it seems.
Could it be because of my previous modifications, or a new bug from yunohost 12 ?
Thanks a lot !
