Upgrading Ubuntu from Breezy to Dapper


By steve - Posted on 10 July 2006

I had a test system set up for Ubuntu Breezy Badger and wanted to upgrade to Dapper Drake. It was a much simpler process than you might be used to.

Here's how to do it from the command line:

  1. Backup everything. I'll wait here...
  2. Log in to the console.
  3. nano /etc/apt/sources.list
  4. Do Ctrl-\ (replace)
  5. Enter: breezy (then press Enter)
  6. Enter: dapper (then press Enter)
  7. Ctrl-x and save the changes
  8. Run: apt-get update
  9. Run: apt-get -y dist-upgrade
  10. Wait awhile...
  11. Answer the prompt about sysctl.conf, if you get it (I took the default "N")
  12. Answer any other prompts you get (like for postgresql, proftpd, etc...
  13. Reboot: shutdown -r now
  14. SMP system?
    • If you have an SMP system, you'll probably ended up defaulting back to the 386 kernel, so you'll need to install the latest 686/SMP kernel: apt-get install linux-686-smp
    • Check grub to see if your new kernel is the default: nano /boot/grub/menu.lst
  15. Backup again, to a different backup medium (don't go over your previous backup, duh)
