What is /etc/apt/apt.conf.d/50unattended-upgrades.ucf-old and can I safely remove it?

Question

I recently upgraded from Ubuntu 14.04 to 16.04. Several things did not turn upside down, for example, ttf-mscorefonts-installer (I don’t know why), and while I was trying to install them, I got a warning.

Team...

sudo apt-get install <package>

... and to create the usual behavior, multiple instances of the alert are also created ...

N: Ignoring file '50unattended-upgrades.ucf-old' in directory '/etc/apt/apt.conf.d/' as it has an invalid filename extension

There is a file with the same name but without an extension .ucf-oldin the same directory. Is this a relic of the upgrade process? Can I just delete the "old" file?

50unattended-upgrades.ucf-old ucf [ " " ], , , . .ucf-old . .

ucf manpage:
