`foundationdb-client` installs successfully, however using `dpkg` to install the `foundationdb-server` gives the following error -

```auto
(Reading database ... 322528 files and directories currently installed.)
Preparing to unpack .../foundationdb-server_6.3.13-1_amd64.deb ...

Errors were encountered while processing:

```

Used this command, in case it wasn’t clear -

```bash
sudo dpkg -i ~/Downloads/foundationdb-server_6.3.13-1_amd64.deb

```

Am I doing something wrong? Any help would be appreciated!

Can you try verifying the [sha256 checksum](https://www.foundationdb.org/downloads/6.3.13/ubuntu/installers/foundationdb-server_6.3.13-1_amd64.deb.sha256) of the server deb? I tried just now in the ubuntu:latest docker image and it seemed to work ok.

Thank you very much! The problem was a faulty download. This helped!
