What app is this about, and its version: Roundcube 1.6.12~ynh1
What YunoHost version are you running: 12.1.39
What type of hardware are you using: Virtual machine
Describe your issue
Trying to upgrade roundcube to version 1.6.15~ynh1 the upgrade failed and roundcube can’t be restored.
Removing it and trying to reinstall, the same error occur while installin and it fails.
I’m not really understanding what’s going on, and I’d prefer staying “vanilla yunohost” than trying to follow random suggestions online about this type of issue without understanding enough what suggested commands do.
If anyone here have suggestions, they are very welcome 
Thanks as always for the amazing software and kind community
