How to write `lsb-release` again on Ubuntu 14.04?

I had to edit lsb-release to make the Intel 1.0.7 graphics installer work on my Ubuntu 14.04 following this article (this is for Ubuntu 14.10, but also suitable to Ubuntu 14.04). However, I forgot to run:

sudo cp /etc/lsb-release /etc/lsb-release.backup

and I accidentally deleted everything in the lsb-release file.

I cannot reinstall base-files as suggested in a comment:

$ sudo apt-get install --reinstall base-files
dpkg: error processing package plymouth-theme-ubuntu-text (--configure):
 subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
 plymouth-theme-ubuntu-text
E: Sub-process /usr/bin/dpkg returned an error code (1)

The following also returns the same error as above:

sudo apt-get install --reinstall lsb-release

How can I write this text file again?

For those who visit this now, these are the contents for Ubuntu 20.04.1:

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=20.04
DISTRIB_CODENAME=focal
DISTRIB_DESCRIPTION="Ubuntu 20.04.1 LTS"

Edit these according to your version.
