## Install

Install Fenris from its package channel after following the [package setup instructions](https://git.bongbetic.com/xavierk/Fenris/src/branch/main/README.md#install-from-package-recommended):

```bash
sudo apt update && sudo apt install fenris       # Debian / Ubuntu
sudo dnf install fenris                          # Fedora
sudo zypper install fenris                       # openSUSE Tumbleweed
sudo xbps-install fenris                         # Void Linux
```

For Void Linux, configure the XBPS repository first:

```bash
sudo xbps-install -S https://git.bongbetic.com/xavierk/Fenris-xbps/raw/branch/stable/x86_64
```

## Verify downloads

```bash
gpg --output SHA256SUMS --decrypt SHA256SUMS.asc
sha256sum -c SHA256SUMS
```

## Rollback

Installing an older package over a newer observation store is unsupported. Restore the observation-store snapshot, then install the earlier Release; see the [upgrade and rollback guidance](https://git.bongbetic.com/xavierk/Fenris/src/branch/main/README.md#upgrade).
