[SOLVED] apt-get update does not work

Eoin Dubh · 02-24-2017, 11:52 PM

I have been asked to fix a phpBB system running on Ubuntu 16.04. It has been a couple of years since I worked with Ubuntu I have forgotten a lot. I have installed a virtual Ubuntu 16.04 server in VMware Workstation and have networking set to bridged mode. I can ping the IP addresses that are in the sources.list file and I can ping the names. But when I run apt-get update it fails to connect to any of the URLs. Any ideas on how to get past this? My home network does not use IPv6 and some of the IPs that show when I run apt-get update appear to be IPv6 but even the IPv4 addresses cannot connect.

Any suggestions?

I assume you are using

Code:

sudo apt-get update

If you list your sources.list. And maybe your sudoers file to make sure
the user is allowed to update like they are admin.

This VM way you are using is above my paygrade however. Maybe the VM is not allowed sudo privileges on a remote box.

in addition to what rokytnji said & requested, can you post the output of

Code:

ping 8.8.8.8
ping archive.org

It makes no difference if I am logged in as root or using sudo from my login. The command hangs on the first lookup. If I change the url from us.archive.ubuntu.com to just archive.unbuntu.com, it still hangs, but the IP changes from 207.241.224.2 to 91.189.88.149. Changing the url to archive.unbuntu.org changes the IP to 198.105.224.130.

Could you possibly paste the output from apt-config dump so that we can check that there are no obvious apt configuration problems that might be causing the problem?

Eoin Dubh · 02-25-2017, 09:07 PM

How do I do that as it is a fresh install with nothing other that the base system and I can't get it to update or install anything. There is no graphical interface and I cannot FTP to it to get the dump file which is @ 6 screens long.

frankbell · 02-25-2017, 09:24 PM

What are the contents of your /etc/apt/sources.list file?

Eoin Dubh · 02-25-2017, 09:52 PM

It seems that since the install is not totally finished, i.e. the update and upgrade have not been run, I cannot install the VMware Tools to setup a shared directory with the host to get to the dump file. And I cannot screenshot the VM window. I can ping the host from the VM and can also ping the router, the DNS servers and the IPs that show when I run the update command, I just cannot connect to any of the Ubuntu repositories. This whole exercise is the setup a dev setup to try upgrading a phpBB system to the current version. It is currently been running since 2 Feb 2003 and has almost 13,000 users and almost 200,000 posts so I want to work out the upgrade methodology in a dev environment first before touching the live system. I will have to think about it overnight and see if I can get it to work. Is it possible to download the update programs and burn them to CD/DVD?

Make sure that you have a working

Code:

/etc/resolv.conf

please post the COMPLETE output.

ohdoho,

As I said several posts ago, I cannot get a screenshot of the screen. In both instances of the pings the output was the same for as long as I wanted it to run.

c0wb0y,

resolve.conf shows:
nameserver 68.94.156.8
nameserver 68.94.157.8
nameserver 8.8.8.8

The first two are the nameservers from my ISP.

frankbell,

The output of the sources.list is 3 above yours.

rokytnji · 02-26-2017, 11:39 AM

Just curious if you tried

Code:

sudo -i

then password

then as root

Code:

apt-get update

Just poking and hoping here.

How did you produce the output from nano /etc/apt/sources.list in post #4?

You would use the same technique to produce the output from apt-config dump.

Eoin Dubh · 02-26-2017, 12:49 PM

hydrurga,

I have several installs of Ubuntu in various virtual machines for different dev purposes. I took a dump from one of then and edited it so that was the same as the new one.

hydrurga · 02-26-2017, 12:59 PM

Ah, I see. If, apart from the problem at hand, you have internet access on the VM, why don't you upload the file onto the internet and then download it onto your main machine? Or, if not, save it to a USB stick and transfer it across? Or is the latter dependent on VMWare Tools?
