I recently ran into a couple problems. When I try to do a upgrade by running the following command "aptitude full-upgrade". I get the following error. To correct that I tried giving myself root access and got the following error after issuing the following command Can someone please help me with this problem. I'm using Ubuntu 9.04 with ISPConfig 3. This problem only started recently and I had been running with no problems for the last 3 wks
Did you somehow modify the /etc/sudoers file? Do you have another user that you can log in with? Did you set a root password before? Then you can log in as root directly.
there was no changes to the /etc/sudoers file. I followed the how to set up and and only created one user. As I said had no problem until recently. I checked the /etc/sudoers file but can't make any changes since I don't seem to have root access. For security purpose I can't log in as root
I guess there's something wrong with the sudoers file. Since you cannot access it, the only way to repair the system is to use a Live CD such as Knoppix. This tutorial should give you the idea: http://www.howtoforge.com/how-to-reset-a-forgotten-root-password-with-knoppix
