Just want to mention I don't have these problems with other distributions. This started like about 2 weeks ago, when I decided to upgrade to Ubuntu 8.04. At first everything was working great. Until I did a couple updates and then "root access was not allowed in user profiles anymore" I try to bring up terminal and I get a quick flash and it is gone. The only place I am allowed access now is in root. I have opened konsole and typed the sudo su - command and it says "sudo: must be setuid root" And if I try and change this it then tells me it can not do that.
Now I have the idea that my installation is crap and it problem needs to be cleaned out, formatted. A clean install back in, or is there a quick fix?

There probably is a quick fix - but it would be good to know what exactly you've done. It looks like you maybe chowned/chmoded what you shouldn't have, maybe /usr.

That's the thing, I have not changed the settings on anything. In the 8.04 they have this Authorizations program built in (and no, you can not remove it, I tried and Ubuntu would not run right) There I added users to certain accounts to have access to certain devices, but that was it. As for chowned/chmoded for users, no.
The root ID is 0 in Ubuntu, the first person has ID of 1000, the second ID of 1001, the third has 1002. But in none of these account except for root am I allowed root access. In the Ubuntu 7.10 I was allowed this access and in the 8.04 I am not.
Sounds like a bad bug. I had the same problem when I went from 7.04 to 7.10 upgrade. I fixed it by doing a clean install. Somewhere in the root files something got buggered up, there the profiles were OK. I believe it is the same problems.
Other minor glitches, are the fact that certain programs are installed and Ubuntu tells me they are not. Or the fact that a main server for updates are no longer available, these tell me the install root files are corrupt. But I was wondering if there it a quick fix for this, that you know of?

The quickest "fix" might be what you did previously - a clean re-install. Ubuntu "upgrades" are murky; I never use it.
I set up a separate partition for /home, and move everything over there. On re-install the new version will recognise everything you use (mail/browser settings, that sort of thing) if you use the same user and password.
Much gooderer.

You can even successfully go back the other way - I had to a couple of times during the Hardy alpha/beta stages.

Well, I fixed part of my problem, now I just have to get the terminal program to work. I guess I will have to read my bible. Thanks all for your help.
