# Installing the Debian Trixie bundle

The release ZIP contains packages built together from the recorded source
inputs.  On a fresh Debian Trixie host, inspect the package list and run:

```sh
sudo ./install.sh
sudo bongo-setup
sudo systemctl enable --now bongo.service
```

The installer verifies `SHA256SUMS`, refuses a non-Trixie system, checks that
all patched libraries carry a `+bongo` version, installs the required runtime
libraries before Bongo, and verifies the installed versions.  It then holds
only these patched dependency packages:

- `libmailutils9t64`, `libmu-dbm9t64`, and their version-coupled
  `mailutils-common` data
- `libspf2-2t64`
- `libsrs2-0`

Bongo itself is not held and can be upgraded normally.  Before deliberately
replacing the patched libraries, run:

```sh
sudo ./install.sh --unhold
```

Review the next Bongo bundle's manifest and installer before upgrading and
let that bundle establish its new library holds.  Do not use `dpkg --force-*`
to bypass an MTA conflict: remove or migrate the old MTA deliberately.
