Hardy Headaches

[Scotsgait]

Could anyone help me through what I need to do to sort out a couple of issues I'm having since upgrading my Kubuntu 7:10 to Hardy Heron ?

The first problem I came across was that Adept is no longer launching. Someone one the IRC Channel directed me to a historical issue which requires me to change a setting in /etc/hosts

The advice was helpful but .... I can't get save file once amended. In fact, it appears that I can't get into administrator mode anywhere (or, at least, in the applications I've tried).

Any guidance (the simpler the better) would be appreciated.

Many thanks

cat /etc/sudoers

Re: Hardy Headaches

Thanks. I entered that in a terminal window and got the response:

cat: /etc/sudoers: Permission denied

Re: Hardy Headaches

could u walk me through what u did before. as in: tell me the commands you did to edit /etc/hosts and what you changed in it? and what happened when you tried to save?

Re: Hardy Headaches

In the console, type:

sudo su

You will be prompted for you password. If it is accepted, your prompt will change from a $ (user) to a # (root). If that does not work, reboot your system and choose to boot into Recovery Mode (single user), which will boot as root to the command line prompt.

Re: Hardy Headaches

My etc/hosts file reads:

127.0.0.1 localhost
127.0.1.1 dad-desktop.MSHOME

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

I was told that the second line is wrong and should read

127.0.1.1 dad-desktop


If I edit the file and try to save it, I get a warning

The document could not be saved, as it was not possible to write to file:///etc/hosts.
Check that you have write access to this file or that enough disk space is available.

I can't run any program using kdesu for some reason .

I've just tried the console command and got

dad@dad-desktop:~$ sudo su
sudo: unable to resolve host dad-deskto

I'm not familiar with Recovery Mode. Can you explain a bit more, please ?

Thanks

Re: Hardy Headaches

Assuming you have Grub boot menu when you boot, it is the second one in the list, so just press your down arrow once and then press enter.

It goes through a Grub process, but I don't have a menu !!

Re: Hardy Headaches

That means that the hiddenmenu item in Grub isn't commented out. That's okay though. There is a default 'timeout' setting that delays for a few seconds the booting of the default entry. All you have to do after booting is to hit your escape key (this stops the timer) and then press the down arrow key just once and press enter.

OK. I've done a reboot. I noticed something failed in the process (but I'll have to reboot again to find out ?)

It then came to a three option menu - Continue Reboot, Something about he X-Server and one other item which I can't remember.... >

What failed was a mounting of something which I presume will be irrelevant.

The third entry was in the menu took me to a terminal prompt. I did the sudo su command again and still got the unable to resolve host dad-desktop message

Re: Hardy Headaches

If you're at the terminal prompt, you (should) already be 'root.' Is the prompt a # sign?

Aha ! Yes, it was.

What should I do from there ?

Re: Hardy Headaches

As 'root' you can edit the /boot/grub/menu.lst file.

From the prompt, type:

cd /boot/grub
vi menu.lst

This will open the file for editing.

Press your down arrow key until you are on the line that reads hiddenmenu This line is probably uncommented (has no # in front of it). If this is so, press the letter i (for insert mode) and press shift+3 to insert the # symbol. You should now have #hiddenmenu

Press escape (this puts you back into command mode)

To save the change and exit, press :wq (a colon, w, and q all together)

Type cd and then type:

shutdown -r now

to reboot. You should be presented with the Grub menu now. When you see it, press escape to stop the timer. You can then use your arrow keys to move up/down the list of kernel entries to boot from.
