Changing UTC / Timezone / Network Time

73ChargerFan · 2010-05-25 02:01:00

When I installed Statler Alpha, I didn't understand the UTC question and chose incorrectly.

A dual-boot computer with Windows, should have the hardware clock should be set to local, not UTC.

To set it to local time, set UTC=no in the file /etc/default/rcS
To change timezone, run sudo dpkg-reconfigure tzdata
To manually update time, install the ntpdate package and run sudo ntpdate pool.ntp.org

Cool thanks for that Chargerfan!

Thanks a lot for this. Somehow, my laptop's clock had suddenly gone berserk. I tried sudo dpkg-reconfigure tzdata, but it was still three hours ahead of time. I installed ntpdate, ran sudo ntpdate pool.ntp.org, and sudo dpkg-reconfigure tzdata again, and now the computer knows it's 09:20 and not 12:20 in Helsinki (UTC+3).

How did you install ntpdate?

anonymous · 2010-06-17 00:52:55

sudo apt-get install ntpdate?

Durr. I was on a fresh install and forgot to do apt-get update, so I couldn't at first.

Anyways, this worked. Thank you.

Glad to help.

It took me a few hours reading pages & obsolete HOWTOs before I understood the problem and could fix it. I'm really glad that I could contribute something, anything to the #! community.

Thanks for the help, 73ChargerFan. Worked great.

I tried, but get this:

root@debianludo:/home/ludo# sudo apt-get install ntpdate
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Couldn't find package ntpdate

I also tried

/usr/bin/tzselect

and could set to Europe, Brussels, but the time is still 4 hours off (also after reboot).

Any more ideas to try?

anonymous · 2010-09-04 15:27:50

Make sure to run "sudo apt-get update" first then try installing ntpdate.

That's another issue I have, because apparently I'm not in the sudoers list (that's why you see I went as

su root

first in the above post)

I did find this post somewhat helpful (although not 100% clear either) http://www.go2linux.org/sudoers-how-to but found that in statler doing

visudo

the file is opened in nano hmm (and read that it's safest with vi in this particular case)

Its a known issue:

As for nano, it doesn't matter. Its just a text editor.

ok, so after the line
root ALL=(ALL) ALL
I typed another line
ludo ALL=(ALL) ALL
put a new blank line after that and saved with CTRL-o

I still can't sudo (not after reboot either)

To add your user to the sudo group you can boot in recovery mode (single user mode) and run

usermod -G -a sudo yourusername

If you want every user you create to belong to sudo group, edit /etc/adduser.conf and remove the comments from the lines below (add the sudo group and edit the others to your preference)

# Set this if you want the --add_extra_groups option to adduser to add
# new users to other groups.
# This is the list of groups that new non-system users will be added to
# Default:
EXTRA_GROUPS="dialout cdrom floppy audio video plugdev users sudo"

# If ADD_EXTRA_GROUPS is set to something non-zero, the EXTRA_GROUPS
# option above will be default behavior for adding new, non-system users
ADD_EXTRA_GROUPS=1

the return is:

usermod: group '-a' does not exist

anonymous · 2010-09-04 17:15:48

Try this command:

gpasswd -a username sudo

this gives me

bash: gpassword: command not found

anonymous · 2010-09-04 17:31:18

Run this as root:

apt-get install passwd

Then try running gpasswd again.

wuy · 2010-09-04 17:46:52

Sorry try usermod -a -G sudo username

man usermod for help

I am just wondering: would it not be a good idea to check if the time is correctly set in BIOS? I successfully changed the time with ntpdate (as I told in post #3 above), but afterwards I also corrected it in BIOS since one of the family's Windows gamers notified me that the time is not right on the Vista side of the dual boot laptop.

johnraff · 2010-09-04 17:57:38

In #!9.04 (Ubuntu), anyway, I'm not in the sudo group (nor is anyone else) but I am in admin, and can do sudo commands OK using my password. Maybe this line in sudoers is what's needed?

# Members of the admin group may gain root privileges
%admin ALL=(ALL) ALL

and to make sure you're in the admin group. You can add yourself to admin with

adduser <username> admin

edit: but of course that needs to be run as root! You'd have to reboot into recovery mode to run it.

spot on!
no need to do anything except set it right in BIOS, I thought hmm , but setting it correct in BIOS didn't correct it in #!

I did su root and then entered the command, but got this

E: Invalid operation passwd

EDIT: oops I misstyped and forgot "install"
corrected and yes, now I can sudo smile
thank you nn (that means anonymous, if I remember well)

If you want to continue troubleshooting, check what mirrors you're using.

Otherwise you could try installing it manually:
