# Trying to Install on Linux Mint 18.3 “Sylvia”

## post by Adrian_Keister on Nov 1, 2018

I realize that installing the Lambda Stack on Linux Mint is not technically supported. But as Mint 18.3 is based on Ubuntu 16.04, and 16.04 is Lambda Stack-compatible, I was hoping it would work. I’m getting an error on the `sudo apt update` part of the install:

```
E: The repository 'http://archive.lambdalabs.com/ubuntu sylvia Release' does not have a Release file.

N: Updating from such a repository can't be done securely, and is therefore disabled by default.

N: See apt-secure(8) manpage for repository creation and used configuration details.
```

If this simply means I can’t install the Lambda stack on Linux Mint, I understand. But if there’s a quick fix, that’d be terrific. Thanks for your time!

So the problem is that we don’t have support for “sylvia”. You could try modifying your `/etc/apt/sources.list` to have the following line:

```bash

deb http://archive.lambdalabs.com/ubuntu/ xenial main
```

Then type:

```sql

sudo apt-get update && sudo apt-get install -y lambda-stack-cuda
```

The simple issue is that we don’t have the `sylvia` code word in our repository.

In **Linux Mint 19.1** code name Tessa you can use **Update Manager**.

Open _Update Manager → Edit → Software Sources → Additional repositories →_

Find **_Lambdalabs_** and **_Lambdalabs (sources)_**

Edit/Rename the entry ‘ **tessa**’ into ‘ **bionic**’.

Hey [@jansenicus](https://deeptalk.lambda.ai/u/jansenicus) does Lambda Stack work with Linux mint when you do that?
