Please, I tried to upgrade to 4.1 using the apt-get. I ran the apt-get update and the apt-get dist-upgrade with no problems. But when I ran apt-get upgrade-kernel, I received the following message: E: Invalid operation upgrade-kernel I run Scientific Linux 4.0 in a Pentium IV. The only way of upgrading is via the anaconda installer? Best regards, Claudio Tellez [log in to unmask] >>
