It seems like you may have typed the wrong command. "unable to locate package update" means that your system is unable to find a package called "update".
To update the package list on Ubuntu 20.04, you can use the following command:
```
sudo apt update
```
This will update the list of available packages on your system. After that, you can upgrade your packages using the following command:
```
sudo apt upgrade
```
This will upgrade all the installed packages on your system to their latest versions.
If you still encounter issues, please provide more details about the error message you are seeing and the steps you have taken so far.
