I'm the UbuntuBasqueTranslators admin at launchpad.
some time ago I completed the synaptic basque translation for ubuntu (someone else started it). Today, I finally decided to review tha parts I didn't translate to make it completely coherent.
I had to redo nearly all of the old strings, but now it's perfectly translated to basque (iso--> eu)
I attach the po file of the latest version to this mail, so every distro can use this great tool in basque
