dpkg -L packagename (without version number or .deb extension)

will tell you which files are in a package.

e.g. on Xenial (16.04, not 17.10):

dpkg -L x2goserver

If you really need to restore individual files (see below for the
preferred option), then I would look at the output of the dpkg -L
command for each package you updated on that day.

If you are unsure which packages got upgraded on a given day, run
less /var/log/apt/history.log to find out - or zless
/var/log/apt/history.log.*.gz.

However, the better approach would be to grab the downloaded packages
from your backup (assuming you didn't exclude /var/cache/apt/archives
from your backup*), and doing a reinstall combined with a forced
downgrade, using

dpkg -i --force-downgrade /path/to/all/debs/you/want/to/downgrade/*.deb

That way, your package management and your file system will agree what's
on disk.

*All downloaded *.deb packages are kept in /var/cache/apt/archives/
until you run apt-get clean or similar.

We have been providing snapshotted repositories for X2Go for a while
now, but I'm not sure if they offer packages for Ubuntu or if we're
leaving Ubuntu packaging to Launchpad.  Ionic should be able to tell us
more about this, thus, CCing him.
If you're lucky, you just need to switch repos from Launchpad to our own
and use a timestamp before the version that's broken for you.

Kind Regards,
