Failed to fetch package

All of the sudden I’m having issues with install the php-config package. What gives?

$ sudo apt-get install -qq php-config gcc libpcre3-dev
E: Failed to fetch http://security.ubuntu.com/ubuntu/pool/main/p/php5/php-pear_5.5.9+dfsg-1ubuntu4.21_all.deb  404  Not Found [IP: 91.189.88.152 80]

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

sudo apt-get install -qq php-config gcc libpcre3-dev returned exit code 100

Action failed: sudo apt-get install -qq php-config gcc libpcre3-dev

I’d appreciate any kind of feedback on this.
