[X2Go-User] How to configure 'unattened-upgrades' on debian squeeze to upgrade x2go packages?

[Holger Krause]

Dear all,

I'd like to have all installed packages on my debian squeeze systems upgraded 
automatically whenever newer versions are available. For this, I utilize apt's 
'unattended-upgrade' functionality and the corresponding package 'unattended-
upgrades' (http://packages.debian.org/squeeze/unattended-upgrades). For most 
included apt sources this works flawlessly. However, I didn't manage yet to 
have 'unattended-upgrades' also pick up changes of X2Go packages. In the 
configuration file for 'unattended-upgrades' 
('/etc/apt/apt.conf.d/50unattended-upgrades') one has to identify 'Allowed-
Origins' by an (origin, archive) duple (according to the comment):

----- /etc/apt/apt.conf.d/50unattended-upgrades -----
// Automatically upgrade packages from these (origin, archive) pairs
Unattended-Upgrade::Allowed-Origins {
        "${distro_id} stable";
        "${distro_id} ${distro_codename}-security";
        "X2Go stable";
};
[...]
----- /etc/apt/apt.conf.d/50unattended-upgrades -----

For other sources I use field 'Origin:' from the Release file as 'origin', and 
filed 'Suite:' as 'archive'. Unfortunately, the X2Go Release file 
<http://packages.x2go.org/debian/dists/squeeze/InRelease> does not have a 
'Suite:' field. I tried 'stable' (as shown above), 'squeeze' and 
'${distro_codename}', but none matches.

In <http://wiki.debian.org/RepositoryFormat#A.22Release.22_files> I found this 
remark: "These fields are optional. They may be displayed to the user by 
package management tool or used for pinning. It is suggested that any 
repository published for other users to use fills meaningful information in 
these fields so that the user can tell apart different repositories.

    Description
    Origin
    Label
    Version
    Suite
    Codename"

Would it be possible to add the 'Suite:' field to X2Go's Release files? Or 
does anyone know how to make 'unattended-upgrades' taking X2Go into account?

Thanks for any response in advance,

Holger
