Today I tried to run the upgrade my nginx on my FreeBSD box, and I received the following message:

===>  Vulnerability check disabled, database not found
===>  License accepted by the user
===>  Found saved configuration for nginx-0.7.66
=> ngx-fancyindex-0.2.2.tar.bz2 doesn't seem to exist in /usr/ports/distfiles/.
=> Attempting to fetch from http://connectical.com/attachments/download/26/.
fetch: http://connectical.com/attachments/download/26/ngx-fancyindex-0.2.2.tar.bz2: Not Found
=> Attempting to fetch from ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/distfiles/.
fetch: ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/distfiles/ngx-fancyindex-0.2.2.tar.bz2: File unavailable (e.g., file not found, no access)
=> Couldn't fetch it - please try to retrieve this
=> port manually into /usr/ports/distfiles/ and try again.

Obviously, the FreeBSD box could not download the file. To fix this problem, simply run the following commands:

cd /usr/ports/distfiles/

sudo wget http://files.connectical.com/gentoo/ngx-fancyindex-0.2.2.tar.bz2

This will allow FreeBSD to skip downloading the file from a wrong URL. Now, go back to the nginx port:

cd /usr/ports/www/nginx

and try to install nginx again:

sudo make install clean
