Problem Installing Packages - Please Help!

[southbeach]

Using Ubuntu

I tried to install postfix and ran into problems. The installation returned errors referencing myhostname as being invalid or something to that effect.

I then tried to install webmin to use webmin to setup postfix through webmin. webmin requires perl so I had to install that. I tried installing perl but get this

root@fesweb# sudo apt-get install perl

Setting up postfix (2.5.5-1.1) ...

Postfix configuration was not changed.  If you need to make changes, edit /etc/postfix/main.cf (and others) as needed.  To view Postfix configuration values, see postconf(1).

After modifying main.cf, be sure to run '/etc/init.d/postfix reload'.

I am caught in a catch 22 where I need to install webmin which needs perl which needs postfix which is not installing at all ...

Could you please provide some advise? I have spent a great deal of time at google looking for answers but nothing productive so far.

Thank you all in advance for your assistance.

It looks as if you are using unbuntu
IIRC webmin is in the Unbuntu reporitorys

sudo apt-get install webmin
should be enough to sort your problem.

I think the root of your problem is that you have an error in your postfix configuration. When you install postfix via the apt package manager, it should have started up an automatic configuration wizard. The error looks like you are missing the configuration files like main.cf which should have been configured in the process.

First try sudo dpkg-reconfigure postfix. Here is a link that should have some helpful information on this process.

If that fails, remove the package and try re-installing. I would suggest using sudo apt-get purge ...package name... which will remove the package and its configuration files.
