# What is the best way to update Lambda systems from the command line?

## post by Husafan on Apr 29, 2024

I have broken my lambda system by using `sudo apt autoremove` which removed the `cryptsetup` package.

After getting help from tech support, I was told that I should use the software update and snaps tools inside the Ubuntu UI. I am mainly using my hardware as a server, and don’t regularly have a monitor attached. What is the correct way to update a lambda system from an SSH terminal?

Thanks!

In most cases it’s sufficient to run:

```bash

sudo apt update && sudo apt upgrade
```

By the using of update function code you can update lambda system

Here is a basic syntax

```bash
aws lambda update-function-code --function-name --zip-file fileb://
```
