[Bug 1620208] Re: package update-notifier-common 3.160 failed to install/upgrade: subprocess installed post-installation script returned error exit status 127

[Steve Langasek]

Thank you for taking the time to report this issue and help to improve
Ubuntu.

The file /usr/lib/update-notifier/package-data-downloader belongs to the
update-notifier-common package.  If this file is missing from your
system, you have a corrupt installation.

In addition, your bug report shows that you are running Ubuntu 15.04,
which is no longer supported.  It is strongly recommended that you
upgrade to a supported version of Ubuntu.
