[Spacewalk-list] spacecmd system_listupgrades not working

[Tomas Lestach]

Right,

spacecmd system_listupgrades actually uses the system.listLatestUpgradablePackages API.
Output of this API you can check on your spacewalk at 
/rhn/apidoc/handlers/SystemHandler.jsp#listLatestUpgradablePackages 

basically for every installed server package, that can be upgraded following structure is returned:

string "name"
string "arch"
string "from_version"
string "from_release"
string "from_epoch"
string "to_version"
string "to_release"
string "to_epoch"
string "to_package_id"

so you see for every upgradable package the latest package to that you may upgrade.

What spacecmd system_listupgrades actually does is it returns a package list just according to "to_package_id".
So if you have multiple kernel versions installed, for all the older ones the latest kernel is offered as an
update, what causes the kernel package is listed several times.

An option would be just to remove duplicates from the list.
