[Bug 1556527] Re: tzdate upgrade fails wih invalid format error during Xenial upgrade

[iMac]

So,

I have no idea what happened;  manual setting of localtime to UTC
(command below) fixed the configuration of the package, allowing the
upgrade to continue.

Anyway, I executed the following command to set to UTC, and then
proceeded to complete the dist-upgrade from 15.05, and the error from
tzdata was resolved;  I'll fix my timezone after the upgrade completes.

#ln -sf /usr/share/zoneinfo/UTC /etc/localtime
