I am using my Laptop Ubuntu 12.4 LTS and followed Chad Chenault blog spot. But when I came to his point 3.2.6.2.1 which required my user name & password, I had a message that my ticket cache is currently empty. This seems to be linked to Kerkeros. But why? I have not knowingly installed Kerberos and do I really need it? if not how do I avoid this blockage? Chad's link is http://chadchenault.blogspot.co.uk/2...er-driver.html Since I posted this I have tried to move Kerberos and its associated files KRB5 into /tmp using Sudo & mv but I ended up with core dumps and system errors. I then tried re-installing Ubuntu but failed to remove Kerberos. How does reformat and remove everything to give a clean hard drive ready for a new installation?

Hi:

I had never heard of Kerberos so I looked it up-

I'm not sure if you really need kerberos because unless I am mistaken Ubuntu has it's own authentication for networking. But if your on a server this application may be needed.
Sorry I am not on a server.

Posting those errors could help members with server experience to know what might be the problem.

Not all services and applications can use Kerberos

I Looked up your printer specifications and saw that it has the 802.11b/g wireless card.

You can use a Live CD of g-parted and delete the Ubuntu partitions. (or) You could download a fresh distribution of your choice and install that and when the time comes to partition use the partition manager that comes with the installer to delete those Ubuntu partitions than proceed with the installation. (Unless you have another operating system on your compupter alongside Ubuntu)


Sorry I don't know more-
