Perfect Server Ubuntu 11.04 Build Essential
 
I am stuck on step 18, Install Jailkit.

I double checked my sources.list. Matches the earlier step. Nothing wrong there.

The error message follows:
Code:

apt-get install build-essential
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 build-essential : Depends: g++ (>= 4:4.4.3) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Is there another repository where I can get build essential?

I'd skip it but the tutorial indicates there would be problems later on if I did.

Try:

apt-get install g++

That was my first response that it didn't work.
Code:

@ubuntu:~# apt-get install g++

Try:

apt-get -f install

and then run again:

apt-get install build-essential

Thanks for the quick response, Till.

Here's what happened:
Code:

@ubuntu:~# apt-get -f install

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 build-essential : Depends: libc6-dev but it is not going to be installed or
                            libc-dev
                  Depends: g++ (>= 4:4.4.3) but it is not going to be installed

I'd rather not chase down all the dependencies because that seems like a lost cause.

Different repository perhaps?

Can you post your sources.list?

Have you tried to run
Code:

apt-get update
?

I always run apt-get update after making a modification here.

Looks ok. Did you previously modify the file and mix other repositories in, or has the file always been like this?

lobius 5th April 2012 14:31

I know. Looks okay to me as well. That is the maddening part.

The only time I modified this file was when the tutorial called for it. I believe that was just uncommenting a few lines.

My previous experience in server setup is with the Rackspace cloud. Well I have several sites humming along on it, I cannot do e-mail on the cloud. Such is the motivation for having the server in my house.

I suppose I can start from scratch.
