[QUOTE=tommcd;4503157]How did you upgrade from 10.04 to 11.04? You can not upgrade directly from 10.04 to 11.04. You must upgrade in sequence, i.e., 10.04 > 10.10 > 11.04. Is this how you did it?
In any case, see this on how to reset the password in Ubuntu: http://psychocats.net/ubuntu/resetpassword
If you are unable to use sudo for administrator privileges, see this to fix a broken sudo: http://psychocats.net/ubuntu/fixsudo
If it were me, I would just do a clean install of 11.10, which is the current version. I always do clean installs of Ubuntu. I never do dist-upgrades; and I never have problems like this.[/QUOT]
Great Thanks. I did upgrade in sequence. I will try to reset password.s thanks for your help
