[SOLVED] Hardy Update

[chrismine]

I cannot do any updates after yesterdays updates.

Update manager shows 11 updates available and then when I try to do the updates is just hangs.

When I try sudo apt-get update it gives me unable to resolve host ubuntu without even asking for my password.

My Internet is working.

Synaptic also does not start.

Any suggestions?

Breakage has started it seems!

Any suggestions?

Wait until Alpha 1.

[chrismine]

Ok but I assume I must download the ISO.

Is there no other way to fix this, because I do not have a lot of bandwith.

I started with Gutsy Tribe 5 and the idea is to end up with Hardy without reloading OS. So far I managed to do that.
This is a machine setup for Linux for me to learn and work with it so it is not a big deal.
Thanks.

what are the outputs of "apt-get -s upgrade" and "apt-get -s dist-upgrade"?

[23meg]

You probably won't need to download the ISO; just install all updates as soon as Alpha 1 is out.

Please provide your /etc/apt/sources.list

Thanks but as I see it I cannot update because the terminal will not let me update with sudo apt-get upgrade nor the Software Sources GUI - maybe chrooting an option or will it also not work - never done it before.

[chrismine]

Please provide your /etc/apt/sources.list

Oops cannot because of this error:
chrisjan@ubuntu:~$ sudo gedit /etc/apt/sources.lst
sudo: unable to resolve host ubuntu

[chrismine]

what are the outputs of "apt-get -s upgrade" and "apt-get -s dist-upgrade"?

Error!

chrisjan@ubuntu:~$ sudo apt-get -s upgrade
sudo: unable to resolve host ubuntu
chrisjan@ubuntu:~$ sudo apt-get -s dist-upgrade
sudo: unable to resolve host ubuntu
chrisjan@ubuntu:~$

Seems I am stuck now!!!!!!

Have you tried another Ubuntu server ?

Meny System > Administration > Software Sources

[eremini]

Do you have a root password set? That will allow you to do su and then avoid sudo's b0rkness.
My guess is that you need to edit /etc/hosts
and change
127.0.0.1 localhost
to
127.0.0.1 localhost ubuntu

[elanthis]

Gotta love the blind leading the blind...

Check your /etc/hosts, /etc/resolv.conf, and /etc/hostname files. Possibly also your /etc/sudoers file. If these are indeed broken, you'll probably have to reboot into single user mode to fix them, since your sudo is toasted.

Sounds like your system used to be called 'ubuntu' and now isn't, and sudo is doing a host check when you attempt to use it. e.g., you might have a line like the following in your /etc/sudoers file:

%admin ubuntu=(ALL) ALL

That "ubuntu" should probably be set to ALL.

Thankyou everybody for your responses - luckily I had a root password set and also setup to login to root GUI - made the change in /etc/hosts file:

127.0.0.1 localhost
127.0.0.1 ubuntu
#127.0.1.1 ubuntu.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

The commented line was the problem. Seems everything working again!

What a way to learn Linux - between me and the community we can solve anything!!!!!!!!

Downloading today's updates - let's see what breaks next.

This is fun!

[pmolaughlin]

I am having this problem as well (after upgrading to Hardy) but unfortunately I don't think I set a root password. Is there anything I can do?

[chrismine]

I do not know if this may work - try Alt+F2 to get the run box and type sudo nautilus - then navigate to the hosts file and change it.

If not working I cannot help.

Hopefully a better Ubuntu Guru seet his post and comes to the rescue.

[eremini]

But sudo is br0ken thats the whole problem :P
But, you can run boot from a live cd then edit the required file from there.

[g2g591]

same problem same solution (except I hapened to have a root terminal open before I updated sudo and found its borkness, so I didn't have to use a live cd)

Thanks for your help solving this issue. I didn't have a password set up for root to log into the gui but it's really easy to fix now you've provided the fix for this fault (I had the exact same one). All you need to do if you don't have a root password is to reboot into recovery mode which already has an option to drop you into a root terminal. You can then just edit the /etc/hosts file without needing sudo or a root password.

[ronacc]

a handy thing to have when you are testing is a puppy linux cd, boot puppy and you can mount any drive on your system and poke around and edt etc from the comfort of a gui ;)

[Lord Illidan]

I had this problem too..applied fix /etc/hosts

[ravs53]

Just type gksudo and use open gedit using your existing password. Then open the /etc/hosts file to edit and you are done.

I have the same problem with sudo - have checked /etc/hosts and it looks fine to me...127.0.0.1 localhost
127.0.1.1 laptop-hardy.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

Comment out the line as shown.

[Gina]

OK, I'll try that - thanks :)

A minute later... Oh dear - now gksudo gedit /etc/hosts is just sitting there doing nothing. I'll boot into Gutsy and edit it from there.

[Gina]

Taken that line out and returned to Hardy - no difference - sudo still produces the same error :(

Any other suggestions?

[chrismine]

127.0.0.1 localhost laptop-hardy
#127.0.1.1 laptop-hardy.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
Sorry I recheked my hosts file and if you add it as shown on the first line it should be allright.

[Gina]

Solved it - and found an easier way to edit hosts.

System > Administration > Network ... Network Settings dialog Hosts tab - Add or Delete.

I now have
127.0.0.1 localhost
127.0.1.1 laptop-hardy
etc.

PROBLEM SOLVED!

Thank you everyone for your help - you pointed me into the problem area. The line in question WAS required but should not have had .mshome on the end

[mellowdave]

I was having the same problem, didnt spend much time on fixing it, but I then came on here and found this thread. WHo would have thought that on a linux box, the GUI would have been easier...

HA!

SOLVED here too.

[swegner]

Hello all,

I just wanted to chime in as well. I received this error with the latest Hardy alpha 6 today. I used the GUI method described above and all is well now.

Do we know yet what the cause of this is? I did install some updates today, but I know I've used sudo between then and now. Is there an open bug for this?

[mabovo]

Another solution is to rename in /etc/hostname :

from: laptop-hardy
to: laptop-hardy.mshome

[ExZacly]

You can also fix this through the GU.

Go to System--> administrattion --> Network --> Hosts

Then unlock system and edit hosts from here.
