# Add fish shell to Debian (Buster)

First, add this repository to the file /etc/apt/sources.list

```
deb http://download.opensuse.org/repositories/shells:/fish:/release:/3/Debian_10/ /
```

Next, download and add the key to your trusted gpg keys.

```
wget https://download.opensuse.org/repositories/shells:fish:release:3/Debian_10/Release.key && sudo apt-key add ./Release.key
``` 
Finally, install fish as per usual.

```
sudo apt update && sudo apt install fish
```
Be sure to restart your shell using ```source ~/.bashrc``` and remove the key with ```rm Release.key```

You can remove the key from your trusted keys if you ever feel the need with 

```sudo apt-key del $LAST_EIGHT_DIGITS``` with the digits located between pub and uid from ```sudo apt-key list``` in this case for me it was 75060AA4.
