Make Ubuntu 22.04 less annoying. Remove ESM Ubuntu Advantage

Ubuntu 22.04 Annoyances

Here are a few collected ways I like to customize Ubuntu 22.04 servers. I used to love Ubuntu, but I hate auto updates and snaps. They also put ads and other usless ads diguised as "news" in MOTD. ESM FUD is spread throughout the OS including simple apt functions. You do not need ESM and thus Ubuntu 22.04 has become super annoying. unattended-upgrade is an automatic installation of security (and other) upgrades without user intervention. Consider the ramifications of disabling this service.

Disable unattended upgrades

The Unattended Upgrades feature is enabled by default and it runs at system boot without the user's permission. The configuration is stored in /etc/apt/apt.conf.d/20auto-upgrades

Disable: sudo dpkg-reconfigure unattended-upgrades then a TUI will come up, select "No"

This will not permantently disable the function. After an update it will be enabled. In the file /etc/apt/apt.conf.d/20auto-upgrades change these values from 1 to 0. Even doing this it will

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

OSX McAfee Removal

Removal of McAfee from OSX

Note: This was written in 2015, it may be out of date now.

There are a lot of commands here which I use sudo if you don't know what you're doing with sudo, especially where I rm you can severely screw up your system.

There are many reasons which you would want to remove a piece of software such as McAfee, such as not wanting it to hammer your CPU during work hours which seems like primetime for a virus scan.

I intend this to be a living document, I have included suggestions from peoples' replies.

Postfix Dovecot Spamassassin Roundcube installation/configuration

#Installing configuring Postfix/Dovecot/Spamassassin/Roundcube

I've documented the steps in short to help me reproduce all the steps. Published it here for improvement and as a reference for others. Of course feel free to comment to improve this document.

This Gist is quite big and not all details are fully explained. But if you're going to run a mailserver you should be able to fill in the missing parts. The most important are covered. But be sure to read up to understand the meaning of all the stuff you configure. Since I used a lot of references of other sources (See at the end) I left out a lot of explanation in this document.

Don't forget that I'm not a Postfix/Dovecot/Spamassasin pro either. I just got it working the way I wanted to.

  • Used Ubuntu 12.04 LTS.
  • Set a root password.

##git mergetool

In the middle file (future merged file), you can navigate between conflicts with ]c and [c.

Choose which version you want to keep with :diffget //2 or :diffget //3 (the //2 and //3 are unique identifiers for the target/master copy and the merge/branch copy file names).

:diffupdate (to remove leftover spacing issues)

:only (once you’re done reviewing all conflicts, this shows only the middle/merged file)

Checkout github pull requests locally

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:
