Kubuntu 12.04 Permission Denied errors when starting up

[Predictability]

When I boot up, I get these errors:

Unlcoking the disk /dev/disk/by-uuid/6e270a39-52ff-4db3-9676-41feae30037 (sda5_crypt)

From here it just hangs. I don't know why I'm getting these errors, I just booted up like normal and got these errors. Is there any way to fix this without reistalling?

Try booting into rescue mode, if that doest work, ou can probobly boot from the livecd and 'chmod'

Sorry, I'm a total noob, so I don't exactly follow what you mean. My brother checked the permissions, and he said they looked correct.

It looks to me that some of the items it's trying to set up at boot need to be done as root (administrator) and you don't have that privilege. It could be that permissions for this set up has changed. Before the error occurred was there anything you did to your account or to the system which might change your permission?

My brother removed me from sudoers and set a root password. He also ran "sudo chmod -r" on some of games in /home. Other than that I don't know of any permissions that were changed.

Here's the progress I've made so far asking on 4chan's /g/: http://archive.installgentoo.net/g/thread/S28837666 (semi-SFW).

I reckon if you were able to add your account to the sudo database that problem will disappear.

Also, why have you encrypted your disk (or home partition)? You really only need to encrypt disks (partitions) if your storing sensitive information (or illegal material) otherwise encryption is a waste of time in my opinion.

I haven't logged in yet, so it's already running as root.

As for the encryption, I just want to be secure from anyone who might want to look at my data.

if I were you I would get with your brother as he made the changes to the system that may/may not be the cause of your problems.

definitely their is a serous problem in that the system or root dosent seem to have permission to start up correctly

My brother said the only things he remembers doing is changing the ownership of some files in home to root. It worked, but it seems now randomly this has happened several days after. As far as he remembers, aside from removing me from the sudoers group no other changes were made, which worked. No changes at all were made to the superuser, as far as he can remember.

ok then lets check the permissions of udevd do a

ls -la /sbin/udevd

ans see what you get ......mine is

vinny@Vinnys-HP-G62:~$ ls -la /sbin/udevd
-rwxr-xr-x 1 root root 137304 Oct 11 04:20 /sbin/udevd
vinny@Vinnys-HP-G62:~$

From grub menu list select rescue mode with the down arrow
then use the down arrow at the rescue list to select "root"
That should get you into the root command line prompt

I just ran that, and I got

-rwxr-xr-x root root 13704 Jul 19 08: /sbin/udevd

It's the same as yours.
