Installing on Linux (DEB)

Tectia Client for Debian GNU/Linux is supplied in Debian (DEB) binary packages for Ubuntu and Debian running on the 64-bit x86-64 architecture.

The Tectia installation bundle contains the DEB installation files and the license file.

To install Tectia Client on Debian Linux, follow the instructions below:

Download the relevant installation bundle according to your license type:
- Commercial Tectia Quantum Safe Edition License:
```
tectia-client-<version>-linux-ubuntu-x86_64-comm-pqc.tar
```
- Commercial License:
```
tectia-client-<version>-linux-ubuntu-x86_64-comm.tar
```
- Evaluation:
```
tectia-client-<version>-linux-ubuntu-x86_64-upgrd-eval.tar
```
In the package names, <version> corresponds to the release version and build number, for example 6.6.3.123-1.
Unpack the downloaded tar package.
Select the installation packages. Two packages are always required: one for the common components of Tectia Client and Server, and one for the specific components of Tectia Client.
```
ssh-tectia-common-<version>_linux-x86_64.deb
ssh-tectia-client-<version>_linux-x86_64.deb
```

Install the packages with root privileges:

# dpkg -i ssh-tectia-common-<version>_linux-x86_64.deb
# dpkg -i ssh-tectia-client-<version>_linux-x86_64.deb

Copy the license file to the /etc/ssh2/licenses directory. (This is not necessary in "third-digit" maintenance updates.)
