NetworkManager taking the scenic route

Thanks Phill, I'll see what they can do for me

I've noticed that you can either do the waiting before logging in or after, or half-and-half. All that matters is that you wait 4-ish minutes after booting. Very strange...

Hi,

it's a new day, so let's start with a quick check, to put my mind at ease. Did you run the checkCD option on the installation CD and did it report back that everything was okay?

As it is weekend you should be able to catch a couple of the lubuntu people in

http://webchat.freenode.net/?channels=lubuntu

It is a small team, so it may be a case of logging on and hanging around for a while (I'll be in there anyway), I can then see if one of the guys who was helping with your issue yesterday has some free time today.

Regards,

Phill.

Hi Phill,

I checked the iso (md5) and then the CD when burning it (bit by bit), but I didn't run the "verify CD" in the CD boot options, because I have heard that it generates incorrect errors for lubuntu. I'll go where you suggest, maybe someone there can illuminate us...

Good catch! It gives one error. A bit strange though, because the Nero check didn't give any errors. Have you tried running this on your CD/DVD? Can you confirm it should give 0 errors? If so, I'll go and buy some CD-Rs

Cheers,
Y.

If you haven't reinstalled yet, I'd suggest you try looking at your /etc/hosts file.

cat /etc/hosts

You should see something along the lines of:

127.0.0.1 localhost
127.0.1.1 y-laptop

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

And if you don't correct it accordingly.

The problem is most likely a corrupt hosts file, as it will result in DNS lookup failing on your hostname. Which is what sudo, and many other network aware applications do whenever they start.

Bingo!

Phill, I apologise for having led you on a wild goose chase, I'm an idiot for having forgotten this...

I use a PCMCIA card to get wifi with the laptop. Sounds normal so far. But wait a second: Didn't he say something about a Centrino? Indeed, but the internal wifi chip broke about 4 years ago. So since then I've been using an external adapter.

Ibu, when you pointed out that the state of the network devices could influence something as basic as "sudo", it all fell into place... I blacklisted ipw2100 (the centrino, not the external card), and Robert is now my uncle.

Guys, is there any way of tagging this thread as solved, and maybe adding some keywords in case it can help someone in the future? Ubuntu 10.04 Broken Centrino Blacklist ipw2100

Anyway, thanks a lot, I really appreciate the help the community has given me these last two days. I can now go back to using the fastest 1GHz laptop I have ever owned.

Cheers,
Y.
