So you migrated someone to (xkl)ubuntu? Help him afterwards if needed.

Grab the portable version of Teamviewer, extract it in the home and the migrated person can run Teamviewer so you can help him.

After installation of (xkl)ubuntu, download Teamviewer portable in his home:

download and put in the home

http://download.teamviewer.com/download/teamviewer_linux.tar.gz

or in terminal:

cd /home/user

wget http://download.teamviewer.com/download/teamviewer_linux.tar.gz

extract it:

tar zxvf  teamviewer_linux.tar.gz

cd /home/user/teamviewer9

the user can now run:

./teamviewer

for getting help.

You can make a desktopshortcut for this.

Tested on ubuntu 14.04.
