Hi,
I've splitted the debian repository on two:
* Lenny: Only packages which work on Lenny.
deb http://debian.adenu.ia.uned.es/apt lenny main
* Sid: Unstable packages. May not work on Lenny.
deb http://debian.adenu.ia.uned.es/apt sid main
At this time, the two repositories has the same packages, but this may change in the future. Lenny users should use the first one.
BTW, I updated the debian xowiki page with the new repo.
Cheers, Héctor
