I messed up the root and it won't boot

is where I'm stuck at

Boot to the liveCD and chroot to the installed system, you can then play with permissions all you like.

Why were you messing with so much of the system? Vuze only needs a single folder accessible, not the whole partition.

Thanks for your reply..this mess has me in a bigger mess with deadlines for my work...anyway
yes it was stupid in hindsight, but when reading a bunch of sites on line it seemed right at the time.
Can you give me more details on this chroot...I've booted to liveCD a few times in trying to figure this out, but I don't get very far, becuase I don't know the commands in sudo very well.

I'm in the liveCD terminal now....but not really sure what to do?

I'm thought to just re-install Ubuntu. However, when I try Live CD says there are errors, and I should run fdsck or somehting like that. Well I can't cause can't get to it, except if I go into GParted....there I can check and repair the file system but it says I might lose my data. I mostly wanted to save my thunderbird and mozilla stuff as I have tons of info in each, but I can't move these folders becuase I don't have the premission

well I took the plunge and scan the ext under Gpart...nothing came up...so I went back to installing from LiveCD of course I didn't mark the directory for formatting as I want to save the data, but the installation program says directories containing system files that already exist under any defined mountpoint will be delted during install. That I can't afford so I"m back to wondering how can I get some of my data off that area.

You should have a backup regime if the data is important

You can mount the partitions in liveCD using places and copy the data over to another PC via network, or USB / SD Card etc etc.

It doesn't let me copy the data....I'm trying to access it....

try:

gksudo nautilus

You can now access whatever you wish.

I just don't get what I'm supposed to do after I gksudo nautilus. Anyway thanks for your help. I just went for it and reinstalled the OS. I lost some stuff, but at least I can work.

FWIW:

andy@fileserver:~$ file /etc/udev/rules.d/z.80_user.rules
/etc/udev/rules.d/z.80_user.rules: ERROR: cannot open `/etc/udev/rules.d/z.80_user.rules' (No such file or directory)
andy@fileserver:~$ file /etc/udev/rules.d/
56-hpmud_support.rules 70-persistent-net.rules
70-persistent-cd.rules README
andy@fileserver:~$ file /etc/udev/rules.d/

You could have used the root nautilus to copy data to a remote location / removable media

But its done now, so it's moot
