Locked after UID change

[tripundra]

Hi.

I recently changed the UID and GID for Ubuntu, fromm 1000 to 501.
Did this to be able to open my user directory on the Mac Osx partition. It was working alright , even loged out and back in and it was ok.
After a shut down and reboot, I was not able to open my account. It says I have no permissions to read and right any file.
How can I change permissions again to be able to log in or how do I change all the files permissions to 501?
I'm a newbie so please bear with me!

Hi, tripundra.

I'm eager to help you, but I'm not sure what symptoms you are getting. Can you log in to Ubuntu and get to a desktop? Once you are in Ubuntu, can you try this within an Ubuntu terminal:

cd ~ && ls -l && id -u && id -g

and print the output here for us to look at.

hi Richard,

I can log into my account but like I said I get plenty of error messages.
I do not get a complete desktop, the mouse loads, but none of the deskbar with the menus appear. I cannot load a terminal, afaik. and doing alt+ctrl+del to log out gets a msg saing" couldn't execute command: gnome session-save, etc etc".
I tried log in with root but I hadn't allowed root to log in, so I can not.
There is only one account created.

Hi Richard,

I entered in recovery mode and asked to "Drop to root shell prompt"
pasted the commands you sent and came out as,
total 0
0
0

Don't know if it's what you want!Or if I need to change to my user account,( don't know how to do it)!

thanks
Edgar

in recovery mode you are logged in as root so ~ is /root and id returns root's uid...

@OP:
post:

ls -l /home/username
ls -ald /home/username/
id username

btw, how did you change your uid and gid?

[iamkrazee]

IMO although my method is crude, chown should set the right UID/GIDs.

And the "cd ~" part is why i told you to skip that and go straight for chown. Should work. Please report back.

tried the chown -hr .....
comes out as :
chown: invalid option -- 'r'


did the ls -l /home/tripundra

came out as:
total 0
lrwxrwxrwx 1 root root 56 Jul 15 18:00 Access-Your-Private-Data.desktop -> /usr/share/ecryptfs-utils/ecryptfs-mount-private.desktop
lrwxrwxrwx 1 root root 56 Jul 15 18:00 README.txt -> usr/share/ecryptfs-utils/ecryptfs-mount-private.txt


then : ls- ald /....
came as:

dr-x------ 3 tripundra 1000 4096 Jul 15 18:00 /home/tripundra


then : id tripundra
comes as:

uid=501(tripundra) gid=501(tripundra groups=501(tripundra),4(adm),20(dialout),24(cdrom) ,29(audio),46(plugdev),109(lpadmin),117(admin),122 (sambashare)




I changed the UID and GUI by following the post on Apple users for Ubuntu 9.04 installation.

try:

chown -R tripundra\: /home/tripundra
chmod 0750 /home/tripundra

Hi Just followed the manual again to rechange to UID and GID to 1000
I don't know what the code means but know how to past it! jejeje


Code:

sudo groupmod -g 1000 tripundra

sudo usermod -u 1000 -g 1000 tripundra

And now I'm able to log on,

So it's now working!
Thanks to you all!
If you have an idea on how to change the UID and GUI to 501 and still log in, I would really appreciate!!
As a side line I followed your thread Richard!! It made my Installation very easy!!Thanks
