How to delete gnome-contacts or evolution data?

Question

I have tried

rm ~/.local/share/evolution/addressbook/system/contacts.db

at no avail (contacts still visible in gnome-contacts), then

rm -rf /home/alba/.local/share/evolution/
rm -rf .cache/evolution

at no avail.

The only effect is to make contacts uneditable and throw this error

Cannot modify contacts: SQLite error code `8': attempt to write a readonly database

Therefrom I guess there is some sort of database elsewhere.

Answer 1

I could not find the file but I opened Evolution Contacts, selected all and deleted.
