Share your gutsy install/upgrade experience.

Ubuntuforums are the official support forums for Ubuntu. Many users seek support or help with their Ubuntu system, but not only. The chat areas are also very active. However, when it comes down to the OS, most of the threads are to solve issues, fix things, get encouragements, basically get community help.

As the community grows the forums can fulfill another need: have users come over to get feedback, and if possible, positive feedback.
Frodon has started a thread where you can also share your positive experiences regarding the recent install/upgrade to gutsy, the latest Ubuntu release.

As zasf points it out:

“I’m going to upgrade right now. I wanted to have a look at the forums in order to know some other’s experience before doing it.”

So please, contribute to the thread, answer to the poll, so that your own experience can allow to draw a broader picture of the overall transition to gutsy.

Minor postfix upgrade errors on gusty (fix included)

Quite strange today, I’m using basic ubuntu gutsy repositories and got an error performing the daily upgrade. I’m use to doing sudo aptitude full-upgrade, and it did not run to the end. I forgot to get the full log saved somewhere, but here is what I searched for:

fatal: /etc/postfix/postfix-script: No such file or directory

The fix is in the following launchpad bug: https://bugs.launchpad.net/ubuntu/+source/postfix/+bug/42947

sudo dpkg --remove postfix
sudo dpkg --purge postfix

Then postfix can be installed again:

sudo aptitude install postfix

Unpacking postfix (from .../postfix_2.4.5-3build1_i386.deb) ...
Setting up postfix (2.4.5-3build1) ...

Postfix was not set up.  Start with 
  cp /usr/share/postfix/main.cf.debian /etc/postfix/main.cf
.  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'.

ldconfig deferred processing now taking place

After postfix was reinstalled, the upgrade could run again.
