Have you created accounts on your localhost? Did these accounts get copied to the remote server?
To fix the first error message, you have to set
c::set('panel.install', true);
in your config.php. Make sure to remove this configuration after the Panel is installed.
As regards the other error messages, set the correct file/folder permissions (755/644) => chmod.
You might have to change ownership as well, if the files/folders are not owned by the webserver user (usually www-data) => chown
