Problems with apt-get update, upgrade and install

I am installing Ubuntu Server V8.10 64 bit as a VMware machine (I already have Ubuntu Studio v8.10 running as one) My base OS is WINXP_SP3

I am following the guide "perfect how to Ubuntu server guide" and i have done everything correctly and now i am stuck at this point ...

"root@server1:/home/administrator# apt-get update

I get messages that include the following:

Failed to fetch http://security.ubuntu.com/ubuntu/pool/main/l/linux/linux-libc-dev_2.6.27-9.19_amd64.deb
Could not resolve 'security.ubuntu.com'
Failed to fetch http://us.archive.ubuntu.com/ubuntu/pool/main/g/glibc/libc6-dev_2.8~20080505-0ubuntu7_amd64.deb
Could not resolve 'us.archive.ubuntu.com'

Now, if I go to look for those individual files, they are available, so why are they failing to fetch?

I have checked 'sources.list', 'hosts' and 'interfaces' thoroughly, so am at somewhat of a loss.

 

Addendum to question above.

I assume that every time I attempt to run apt-get the results are logged somewhere, please let me know where I can find these logs.

Thank you!

 

What's in /etc/resolv.conf?

 

Contents of /etc/resolv.conf

domain localdomain
search localdomain
nameserver 192.168.50.2

 

Same problem with 8.04 . . .

Hi, I tried to install the 8.04 LTS server, and essentially had the same problem. I can only surmise that there is something fundamentally prohibitive about my host PC setup.

 

Please try this in /etc/resolv.conf (put it in the first line:

Code:

nameserver 145.253.2.75

 

Thanks, I did add the nameserver in, but . . .

I still seem to have problems downloading some files.

The .doc file in this link is a screenshot demonstrating the issue:

http://baartman.us/images/Ubuntu/

 

Can you post the screenshot here?

What are the outputs of

Code:

ifconfig

and

Code:

route -nee

? What's the gateway IP?

 

Screenshots

Hi Falko, I really appreciate the interest you are taking in my server problems!

The gateway ip is 192.168.1.1

The screenshots are at this link:

http://baartman.us/images/Ubuntu/

 

Can you post the outputs of

Code:

ifconfig

and

Code:

route -nee

here in the forum?

Also, I'd prefer a screenshot in .jpg, .png, or .gif format, not anything pasted into a Word document.

 

JPEGs of Ifconfig and Netstat

They're too large to drop on the forum, so I'll put them on my server again:

baartman.us/images/Ubuntu

 

What are the outputs of

Code:

ping -c2 192.168.1.1

and

Code:

ping -c2 74.125.45.100

?

(BTW, you can copy & paste the outputs by using an SSH client such as PuTTY - no need to create screenshots.)

Falko, I am rather new at this, and have no idea how to get Putty to operate, I tried it from an 8.10 Desktop VM but its not installed there. I did find a "Host Terminal Client" and tried to connect to server1.example.com, but the client cannot find it, allthough both VMs are on the same Host.

 

On Ubuntu, you can simply open a terminal and run

Code:

ssh username@ip_address

to log in. But I doubt this will work because your server doesn't seem to have any network connectivity. Can you undo the changes to /etc/network/interfaces so that the system uses DHCP again? Restart the network and then post the outputs of

Code:

route -nee

and

Code:

ifconfig

again.

 

DHCP does the trick . . .

Hi Falko, I have learnt much about linux networking protocol and syntax in between our correspondence!

Suffice it to say that changing to DHCP has solved the issue. I believe my ISP was blocking my static addressing scheme.

You advice and interest is much appreciated!

 

having kinda the same problem

I followed the step as far as you went with him i reset my /etc/interfaces/ file to defaults to use dhcp and when i restart it gives this dialog:

(sry no pic its on a different machine)
<snip>
Listening on LPF/eth0/00:13:72:d0:4f:bd
Sending on LPF/eth0/00:13:72:d0:4f:bd
Sending on Socket/fallback
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 3
(it repeat line above this 8 times at different interval numbers)
No DHCPOFFERS received.
No working leases in persistent database - sleeping
<snip>
thats my problem so far if there are any of dialogs you need ill be happy to supply them.

 

Do you have a DHCP server in your network (e.g. on your router)?

 

How do i go abought checking that?

 

You can check that in your router's web interface.

 

Yes there is DHCP activated on my router.
But i do not own my router, my internet provider maintains it.

I only know it has DHCP enabled because my laptop is pluged into the same router and the connection details say it is enabled.
