Archived X2Go Packages for Debian GNU/Linux

Alongside with the instructions on the main Debian repository page, we provide a repository archive for archived X2Go Debian packages for deprecated Debian GNU/Linux releases. These are provided in the state they were in after their last successful build. This repository is not updated at all, other than when a new Debian GNU/Linux release version is deprecated.

Adding this Repository to Your Package System

Bootstrapping the Repository GPG Keys

Make sure to either have installed the x2go-keyring package previously or add the GPG key as described on the main Debian repository page.

Adding the Actual Repository

Changing Existing Entries

If you already have the X2Go Debian Repository in your apt sources, the only thing you need to do is changing the repository address from packages.x2go.org to archives.packages.x2go.org.

Adding a New Repository

If this is a new installation on a fresh machine, follow these steps. Note, that these packages are completely unmaintained and bug reports will not be accepted. This also holds for security-related issues.

Please add the file x2go-archive.list to the folder /etc/apt/sources.list.d/. This can be done by using your preferred editor.

If you have not gotten a directory named /etc/apt/sources.list.d/ add the lines to /etc/apt/sources.list. 
$ editor /etc/apt/sources.list.d/x2go-archive.list

Then add the Archived X2Go Packages repository (binaries and sources) as a couple of new lines (example for Debian squeeze):

x2go-archive.list
# Archived X2Go Packages Repository (release builds)
deb http://archives.packages.x2go.org/debian squeeze extras main
# Archived X2Go Packages Repository (sources of release builds)
deb-src http://archives.packages.x2go.org/debian squeeze extras main

# Archived X2Go Packages Repository (Saimaa ESR builds)
#deb http://archives.packages.x2go.org/debian squeeze extras saimaa
# Archived X2Go Packages Repository (sources of Saimaa ESR builds)
#deb-src http://archives.packages.x2go.org/debian squeeze extras saimaa

# Archived X2Go Packages Repository (nightly builds)
#deb http://archives.packages.x2go.org/debian squeeze extras heuler
# Archived X2Go Packages Repository (sources of nightly builds)
#deb-src http://archives.packages.x2go.org/debian squeeze extras heuler

Edit this new data and make sure to uncomment desired components and comment non-desired components. Only one group may be active at a given time.

While we do offer pseudo-codenames like oldstable, stable, testing and unstable for convenience, you should not use them. Our pseudo-codename setup is not guaranteed to be in sync with Debian's releases, so using the stable codename might mean that you will actually get packages for what Debian calls oldstable after a new Debian distro release for a considerable amount of time.
Switching between components usually requires uninstalling all X2Go packages first! The only upgrade path that is considered somewhat safe is main (release packages) to heuler (nightly packages), but there are no guarantees regarding the stability or usefulness of nightly packages.

Synchronize the Newly Added or Changed Repository's Metadata

Please perform an update of your APT package database: 

$ apt-get update
If you were unable to bootstrap the repository GPG key previously, apt-get will fail to validate the signatures and discard the downloaded repository metadata.

Not being able to verify signatures means that any content downloaded from the remote location could be injected/offered by a malicious third party and need not come from the X2Go Project. This includes repository metadata and any packages downloaded from unauthenticated repositories. Installing the x2go-keyring package from an unauthenticated repository bears the chance that this is not our package but a malicious third-party one which will not contain our public keys. This holds for all packages installed from this repository, now and later.

You can bypass apt's internal checks if you understand the implications and are ready to take the risk by once using: 

$ apt-get update --allow-insecure-repositories

Otherwise, please try to first fetch the key again as outlined in the bootstrapping instructions.

After the update you should be able to access the archived X2Go packages via the apt command family. As a first action you should install our x2go-keyring package and refresh the apt cache: 

$ apt-get install x2go-keyring && apt-get update

Post-Addition Test

Now you can search for archived X2Go related packages that are now available for your APT system: 

$ apt-cache search x2go

Congratulations, you are now able to access the archived X2Go packages. You may continue by installing x2goserver, x2goclient or pyhoca-gui or any other of the available packages.

Mirroring This Repository
