• Started dist upgrade at 5:45pm

I didn't feel like burning a CD this time and I had performed a few successful upgrades relying on the servers. My work desktop managed an upgrade in about an hour and a half.

• traceroute is no longer supported by Canonical?

I got errors during the upgrade about these items

• squid (claimed that it didn't upgrade)
• phpmyadmin
• samba
• something about the updater

But, YAY, media wiki didn't get messed up.

php5 mhash.so

• a vestigal php5 config file was left behind for mhash which caused this error to be emailed to root every 30 min:

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php5/20090626/mhash.so' - /usr/lib/php5/20090626/mhash.so: cannot open shared object file: No such file or directory in Unknown on line 0

The bug is documented here: https://bugs.launchpad.net/ubuntu/+source/php5/+bug/541439/+activity

The fix was to remove the file /etc/php5/cli/conf.d/mhash.ini

My fix was to remove the file /etc/motd.tail

amavisd not running

• hobbit says that amavisd is no longer running

synaptic said that amavisd-new was installed, but amavisd-new-postfix was not so I installed amavisd-new-postfix and got this error:

Stopping amavisd: (not running).
Starting amavisd:   The value of variable $myhostname is "weasel", but should have been
  a fully qualified domain name; perhaps uname(3) did not provide such.
  You must explicitly assign a FQDN of this host to variable $myhostname
  in /etc/amavis/conf.d/05-node_id, or fix what uname(3) provides as a host's 
  network name!
(failed).
invoke-rc.d: initscript amavis, action "restart" failed.

I get the same error when manually trying to start amavis:

root@weasel:~# /etc/init.d/amavis start
Starting amavisd:   The value of variable $myhostname is "weasel", but should have been
  a fully qualified domain name; perhaps uname(3) did not provide such.
  You must explicitly assign a FQDN of this host to variable $myhostname
  in /etc/amavis/conf.d/05-node_id, or fix what uname(3) provides as a host's 
  network name!
(failed).

I love lucid and helpful error statements. I entered a FQDN in the config file and restarted amavis.

There were 29 messages in the queue when I got amavis restarted. Within a minute, the queue started to drain by itself.

Now hobbit reports all services are green.

Hmmm, the mail queue is not draining as fast as I would expect. I'll have to follow the path through my configs again. I wish I had written down how it all works a little bit better.

I removed the amavisd-new-postfix package and restarted, but still no joy. New mail is piling up in the queue without being delivered.

sshd refuses connection from localhost

This pisses off hobbit which tests sshd by trying to connect to localhost. So now ssh is showing as yellow in my hobbit report. I'll get to that later.
