Dear all, trying to upgrade from SL 3.0.4 to SL 3.0.5 I followed these steps: 1- update /etc/apt/sources.d/sl.list to use the SL305 repository instead of the SL304 one 2- rpm -Uvh ftp://ftp.scientificlinux.org/linux/scientific/30x/i386/misc/RPMS/apt-sourceslist-30x.SL.i386.rpm 3- apt-get update 4- apt-get dist-upgrade At the last point I get the following error: ... Failed to fetch ftp://ftp.scientificlinux.org//linux/scientific/305/i386/apt-rpm/RPMS.os/rpmdb-SL-305-0.20050725.i386.rpm Size mismatch E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing? Is it a mirror problem? (I got the same using the CERN mirror). cheers, Guillermo -- Guillermo Losilla Anadón Instituto de Biocomputación y Física de Sistemas Complejos de la Universidad de Zaragoza (BIFI) http://bifi.unizar.es/~guillermo/ e-mail: [log in to unmask] phone: (+34)976562212 ext.224
