Do you want to overwrite the 14.04 install? Don't you want to fix the
interrupted release upgrade?

What steps were you doing, to get there. What drive info do you get?

What is broken and what do you want to recover?
I suspect that after the upgrade failed, you were unable to boot 14.04.
If this should be right, then you didn't spend much time to find
help that already is provided and is available by the mailing list
archive.
First try to boot using recovery mode, if this shouldn't work, chroot.

https://help.ubuntu.com/community/LiveCdRecovery
As soon as you have got access run
sudo apt update
sudo apt -f install
sudo dpkg --configure -a
sudo apt full-upgrade
sudo apt autoremove
After this, what does
lsb_release -rc
say? If it's still 14.04 and you shouldn't use third party repositories
run
sudo do-release-upgrade
and don't forget to post the commands you run and the output you got,
if something should fail.
FWIW you are aware that if something fails, you also could take a look
at log files? You could use the copied output of a command or a log
file to google?
