Can you elaborate on this? Looks like a PEBKAC problem to me.

I've not run into anything in Ubuntu I couldn't do via sudo (sudo su - works wonders, even if it is not all that safe). At one time (don't know if it's still possible) you could actually give root a password and then login as root.

Yes you can do sudo -i and use passwd command to enable direct root logins, but you really do not need it.

Of course, even root cannot execute files that have no executable bit set, or delete files with immutable bit set, to name a few cases where root may get permission denied message. This is what goes to PEBCAK category, if you do not know how to use chmod or xattr then you have no business going root.

@ Emerson, I appreciate your interest in this topic, one thing I would like to clarify. Ubuntu was my introduction to Linux approx. 4 years ago and I admit I did not get of to a very good start. However I have come to truly appreciate the help and support of Linux users through forums like this one and others, none more so than the Ubuntu forum where I spent a lot of time asking questions and looking for answers. I genuinely value the help I received many times from members who shared so willingly of their time and expertise. I am indebted to them immensely for helping me as a newbie surmount what seemed a never ending list of difficulties. To all of them, a huge Thank You. Even yourself, I am sure there are far more things you could be doing than spending countless hours helping newbies. There are still some features of Ubuntu I miss but the whole experience after nearly a year of trying to learn linux, left me frustrated to the point that I gave up on linux for about the last three years and have only recently come back after some searching on other Linux sites and being recommended to try Slackware as the system that could address my needs. Again more helpful advice from linux users. I don't want to give anyone the impression I am on an anti-Ubuntu rant, I'm not. My problems can only be attributed to my lack of proficiency at operating Linux.

Ubuntu's goal is to be secure "out-of-the box". By default, the user's programs run with low privileges and cannot corrupt the operating system or other user's files. For increased security, the sudo tool is used to assign temporary privileges for performing administrative tasks, which allows the root account to remain locked and helps prevent inexperienced users from inadvertently making catastrophic system changes or opening security holes
