Error on install

[micropalla]

Hello!
I had to remove Phoca Gallery for a migration from joomla 3 to joomla 4.
Now on J4 i try to reinstall it but I receive this error:

JInstaller: :Install: Errore SQL Duplicate entry '1' for key 'j25_phocagallery_styles.PRIMARY'

I also receive this installing a new component:

Joomla\Filesystem\Folder::files: Path is not a folder. Path: [ROOT]/administrator/components/com_phocagallery/

What can I do to fix it?

I then created missing folders but I receive this error:

JInstaller: :Install: Non è stato possibile trovare il file di setup XML
JInstaller: :Install: Errore SQL Duplicate column name 'image_id'

Hi,

JInstaller: :Install: Errore SQL Duplicate entry '1' for key 'j25_phocagallery_styles.PRIMARY'

see, the Official Phoca Migration Guide J3 --> J4

Exporting data (Joomla 3)
[..]
These are all tables starting with:

Phoca Gallery: jos_phocagallery (#__phocagallery) (except jos_phocagallery_styles - there are completely new styles in Joomla 4 so old will be not compatible)

Kind regards,
Benno
