Changes between Initial Version and Version 1 of Ticket #37531, comment 8

initial	v1
1		This issue also affects the Theme Install screen. The problem is less likely to happen because WordPress assumes a theme is installed when seeing the directory of that name. To recreate the issue (without the patch of course): Go to the Theme Install screen, then create a directory that matches the slug of a theme, then back on the WordPress ~~patch~~ try to install - it will produce the exact same result. In [attachment:37531.3.diff] I adjusted `wp_ajax_install_theme()` to include the error code as well, similar as in `wp_ajax_install_plugin()`.
