The mirror "ftp.utexas.edu" is outdated.
Please try other mirror, such as "ftp.us.debian.org". I have checked that xz-utils_5.1.1alpha+20120614-2+b3_amd64.deb exists on this server. ________________________________ 发件人: Robert F.

I've installed numerous other packages with apt-get on this Intel iMac, running jessie, without problems. Internet connection is OK. I ran apt-get upgrade and ran with --fix-missing with no change.
