Mirror mirrors.cat.pdx.edu is out of date

[Jean-Paul Larocque]

I couldn't install isc-dhcp-server, due to isc-dhcp-server lagging behind the isc-dhcp-common package:

$ sudo apt-get install hostapd isc-dhcp-server
Reading package lists... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 isc-dhcp-server : Depends: isc-dhcp-common (= 4.3.1-6) but 4.3.1-6+deb8u2 is to be installed
E: Unable to correct problems, you have held broken packages.

I found that the root cause for my experience is that mirrors.cat.pdx.edu is out of date:

NO_PROXY=\* curl --head http://mirrors.cat.pdx.edu/raspbian/raspbian/dists/jessie/main/binary-armhf/Packages.xz

For comparison, this other mirror seems to be okay. Compare the Last-Modified time:

I hope that helps. Thanks!

I've added a note to the mirror list and sent an email to the operators of the mirror.

This shouldn't affect users of the mirror redirection system because that works on a per-file basis
