When attempting to update Ubuntu from version 14.04 LTS to 16.04, you may encounter an error when entering the following command:

do-release-upgrade

This error is caused by non UTF-8 characters in the /var/lib/dpkg/status file. Follow the instructions below to identify and remove these characters.

Enter the following command:
```
grep -avx '.*' /var/lib/dpkg/status
```
This will display any not UTF-8 characters in the file.
Enter the following command:
```
sudo nano /var/lib/dpkg/status
```
Locate the bad characters, and delete them.
Save the file.

Enter the following command:
```
dpkg -l | grep linux-image
```
This will display all the kernels currently installed. All but the most recent can be safely deleted.

Enter the following:

apt-get remove ''old-linux-kernel-package-name''

Ex: ''apt-get remove linux-image-3.13.0-32-generic''
